A Note About This Reference

This Seiko Divers Reference covers the standard 150m & 200m automatic models that Seiko has been making since 1965. It also contains some information on the "high-end" Professional Divers.

The information here is compiled from postings of folks who share their knowledge and insights with each other every day on the Seiko & Citizen Forum. Basically, everything here is a product of the collective WISdom of Seikoholics. What I've done is simply to go through the archives and compile the relevant info in one place so those who are interested in the history and folklore of Seiko divers can use this as a reference. I hope folks will find this useful. I've certainly learned a lot just by putting all the materials together.

Please feel free to share and use the information here. By all means email me if you think anything needs to be changed. And keep in mind that this is a work in progress. There may be dates that are incorrect or details that are inaccurate. So corrections, criticisms, suggestions, and feedback are always welcome and encouraged.

Enjoy your Seikos and see you at the S&C Forum!

About the Chronology

For the production dates of the different diver models, I emailed Seiko Japan and asked them to provide detailed info about each variation (the 62MAS, 6105s, 6309s, 6306, 7002 and the 7S26 series). Seiko provided the "approximate" dates of production for the difference movement calibers, but said they are unable to give info about individual models as they don't have detailed records. (Their email reply is here for those who are curious.)

6217

  • Production: 1965 - 1968
  • Movement: Cal. 6217
  • Description: 150m diver

6217 gallery

Models:

  • 6217-8000
  • 6217-8001
  • also referred to as "62MAS" or by dial number -- 6217-8000T.

Details:

The 6217 is Seiko's 1st diver. It's often referred to as "62MAS" (the 62 stands for the 62 series caliber movement used in the diver). It's rated to 150m.

(For a good intro to the history of Seiko's development of the professional divers, see Ryan's post from the Seiko & Citizen Forum here.)

The cal. 6217A automatic movement is 17J and runs at 18,000 bph. It has a date-only display and was used also in the World Time models. 6217A is a cousin of the 35J 6218A movement, which has an added day wheel and was used in the Seikomatic and Weekdater models of the late 60's.

6105

  • Production: 1968 - 1977
  • Movement: Cal. 6105
  • Description: 150m divers

6105 gallery

Models:

Models with symmetrical cushion cases:

  • 6105-8000
  • 6105-8009

Models with large asymmetrical cushion cases:

  • 6105-8110
  • 6105-8119

Details:

Seiko made 2 series of 6105 divers: 6105-8000 and 6015-8009 are earlier models, while the 6105-8110 and 6105-8119 come later. All models are rated to 150m.

The cal. 6105 movement comes in 2 variations -- 6105A and 6105B. They are both 17J and run at 21,600 bph. They have a quickset date-only calendar mechanism.

From comments made by owners of 6105 divers, it seems that are 6105 movements that hack and there are some that do not. In a S&C Forum post, "ed jacobson" says, "The first series 6105 does not hack. The dial is signed 'waterproof'. The type that hacks will have 'water resistant' on the dial." But Mike/"mmounce" says, "I have 3 that all hack. One of them is an early model with water 'proof' instead of 'resist' on the dial and caseback and it hacks also." So it's unclear which specific models of the 6105 divers hack and which do not, though both exist.

The 6105-8000 and 6105-8009 models use the cal. 6105A movement and have symmetrical cushion cases. The 6105-8110 and 6105-8119 models come later and use the cal. 6105B movement and have larger asymmetical cushion cases.

The 6105 divers use the turn and lock mechanism (and not a screw-down crown).

Here's a detailed description of the different models by "petew":

The 8000 and 8009 are the same watch. Seiko just assigns a 0 or a 9 as the last digit depending upon the country that the watch was exported to. I'm not sure where the 0's vs. the 9's were destined for though. So anyway, the same goes for the 8110 and 8119. The 800X series preceded the 811X series.

There are differences between the 8000(9) and the 8110(9).

First of all there's the bezel. It's bi-directional without clicks on the 800X series. The 811X's are unidirectional with clicks. [Correction: The 811X should be "bi-directional with clicks." According to Mike/mounce, "The smaller cased 8000,8009 do not have a click ball,just friction o-ring for tension.The large case 8110,8119 have the click ball."]

The 811X's are also much larger at around 45mm vs 41mm. Some like the slightly asymetrical case design of the 811X's while others like the more conservative 800X's...

Neither of the two watches can be manually wound, but some (maybe all) of the 811X's actually hack. One really nice feature that you get with the 800X's is a signed crown. A real rarity with Seiko both vintage or contemporary.

Ever since Seiko started putting out its line of hardcore diver's watches, folks have been using them for all sorts of extreme situations.

Here's an anecdote from S&C Forum contributor John Miller about what he and his 6105 went through:

My trusty 1966 6105 Diver has withstood one Alaskan plane crash (small plane) after being left in the woods "lost" for 6 months after it broke from my wrist and flew out on crash impact until we could come back and salvage the aircraft in the spring. (Lived in Alaska 24 years) Another was our helicopter went down in the North Atlantic in the late 70's during a storm and a trip to the offshore oil platforms, we were in a raft for 7 hours in heavy seas and freezing spray. A refinery explosion in France in the 80's when several people close by were killed and my Seiko once again became airborne and was found several hundred feet away. I just had in restored by Eric in Seattle of EMW and it's looks like a new watch. Any way I guess that's tough..............

The 6105s and the 6309s that follow them were popular especially among American soldiers who bought them cheap from the PX.

According to a S&C Forum contributor, the 6105 divers were issued to one of the U.S. Navy Seal teams in the 1960s.

In the 1979 Francis Ford Coppola film "Apocalypse Now," Captain Willard (played by Martin Sheen) was an Airborne Army Ranger who wore a 6105 diver. There's a closeup video capture shot of the watch here (pic by Mike/mmounce).

The 6105 supposedly also appeared in the "The Deep." According to Jeff the "watchdude," "The character 'Romer Treece' wore 2 Seikos actually, one was a VERY old 60's 150m dive model (non-locking crown) and the other was certainly the 6105-8XXX (of Apocalypse Now fame) in a brief underwater shot."

6306

  • Production: 1976 - 1981
  • Movement: cal. 6306
  • Description: 150m divers

6306 gallery

Models:

  • 6306-7000
  • 6306-7001

Details:

The cousin of the 6309, the 6306 is a 150m diver that looks and feels identical to the cushion-cased 6309, but was marketed only in Japan and uses the cal. 6306 movement.

The cal. 6306 movement has 21J and runs at 21,600 bph. It hacks and has a quickset day/date calendar mechanism with a Japanese/English day wheel.

The 6306 divers are much rarer to find than the 6309s because their production years were relatively short and they were Japan-only models that use a 21J hackable movement (compared to the 17J non-hacking movements in the 6309s). Like the 6309, the 6306 diver has a bi-directional non-locking bezel.

According to Mr. Tokunaga, the designer of many of Seiko's diver watches, the 6306 diver was put into production slightly before its brother the 6309. The 6306 diver differs from the 6309 in that the cal. 6306 movement has 21J (as supposed to its base caliber 6309's 17J) and it has a Japanese/English day wheel. A promotional pic of the 6306 diver from an early Seiko catalog is here. [Also see description of the 6309 below.]

6309

  • Production: 1976 - 1988
  • Movement: cal. 6309
  • Description: 150m divers

6309 gallery

Models:

Models with big cushion cases:

  • 6309-7040 (all have big cushion cases and black bezels, though some have seen 6309-704X divers with blue-and-red bezels)
  • 6309-7049

Models with slimmed-down case:

  • 6309-7290 (start of the use of slimmed-down cases, black-bezel version)
  • 6309-7290 with "17 JEWELS" on dial (Japan-made version, with black bezel)
  • 6309-729A (identical to 6309-7290 except with blue and red bezel)
  • 6309-729A with "17 JEWELS" on dial (Japan-made version, with blue and red bezel)
  • 6309-729B? (very rare model, with slimmed-down case and orange dial)

Details:

The 6309 divers replaced the 6105 as the standard models of 150m divers. The 6309s were marketed outside of Japan while a version using the 6306 movement was sold only in Japan (but for a relatively short 5 years).

The cal. 6309 movement is a successor of the 6105. It has 17J and runs at 21,600 bph. It's non-hacking and has a quickset day/date calendar mechanism.

Like the 6105, there are 2 series of 6309 divers. The earlier versions -- 6309-7040 and 6309-7049 -- are housed in big cushion cases and have round markers. The later versions -- 6309-7290 and 6309-729A/729B -- have slimmed-down cases and rectangular markers (which make them very similar to the current SKX007/173 models). While the earlier 6105 divers used the "turn and lock" crowns, the 6309 crowns are all screw-down. The 6309 divers seem to all have bi-directional non-locking bezels.

Some people have asked how the 6309-7049 and 6309-7040 differ. The consensus among S&C Forum collectors is that there's no difference between the 6309-7040 and 6309-7049 models. John Davis/ei8hthoms explained that the last digit of the case number indicates a regional code used for marketing (9 means N. America and 0 means elsewhere).

Mr. Tokunaga, the designer of many of Seiko's diver watches, has provided some valuable historical info about the 6309/6306 divers here. The 6309 and its brother the 6306 were both put into production in 1976 -- the cal. 6309 movement was designed first (and serves as the base caliber for the 63 series of movements), but the 6306 diver was put into production "slightly first," before the 6309. He also included a scan of the original specification drawing for the 6309/6306 divers as well as promotional pics of the 6309 and 6306 watches from early Seiko catalogs.

For a comparison of the details of the 6309-7040 and 6309-729A with lots of pics, check out Mark Skorji's post here.

There are many anecdotes of folks who have put their 6309s to the torture test.

I've come out of lurking mode to present my version of an extreme torture test on the 6309-7049 150mm diver... this watch spent over 1100 hours underwater...I was a contract diver who worn the Sekio as a good luck piece....not a part of my working system....I had made a 4" rubber band cover out of a leg tourniquet to fit over the watch...pipelay barge or dredge or jet barge divers and Non Destructive Testng divers don't wear watches....strange?...Not really..the limited visiablity conditions where my type of diving takes place were river bottoms and mid harbors(the sekio was there)in 76 Boston Harbor USA had 12' of overburden above harbor floor(the 6309 was there)...biopsy (coreing sampling) a bridge spanning the Mississippi.. easy current.. no visibility (the sekio was there)torque valve on the hydraulic machine slammed my wrist into a piling...(the seiko was there)I add that I did wear a 50cm depth gauge at all times..the incident broke a bone in my wrist it moved the bezel to one side..new bezel and crystal... the watch was find... destroyed my GG..the Seiko had 5 years of this real time torture test... I also played in my Sekio..this was a 24hr watch...the watch has been restored now by IWW... Jack related not a spect of rust on the movement... it is still my everyday watch though its diving days are over...so when a watch is nominated as one of the most robust and enduring divers... with a strong record to prove by....I believe my unintentional real life torture test on my 6309 speaks well of the watch.

The 6309 divers (like the 6105s before them) were extremely popular among the military. Read the annecdotes here: "17 Year Long Torture Test, Seiko 6309."

Ed Harris wore a 6309-704x in the 1989 movie "The Abyss."

In this 1983 photo, Mick Jagger is wearing a 6309-704x.

7002

  • Production: 1988 - 1996
  • Movement: cal. 7002
  • Description: 150m & 200m divers

7002 gallery

Models:

  • 7002-7000
  • 7002-7001
  • 7002-7009
  • 7002-700A (blue and red bezel)
  • 7002-700J (Japan-only version, with "17 Jewels" on dial, blue and red bezel)
  • 7002-7020 (200m model with a steel Tag-like bezel design similar to the current SKX171 model)
  • 7002-7039 (200m model, in black as well as blue-and-red bezels)

Details:

The cal. 7002 movement has 17J and runs at 21,600 bph. It's non-hacking and has a quickset date-only calendar mechanism.

By the late 1980s, Seiko has changed the case design of the divers from the earlier large cushion shape to a slimmed-down case like we see today in the SKX007/173s.

When the 7002 divers replaced the 6309s, they inherited the small case design from the 6309-7290. The 7002s all have rectangular markers.

There are several different variations of the 7002 divers:

  • The 7002-7000 and 7002-7009 seem to be identical, with the difference being only the marketing regional code at the end of the case number (0 and 9). These 2 are both 150m divers. Their inscription says "WATER 150m RESIST" on the dial.
  • The 7002-7001 is almost identical to the 2 above but the dial has the line "17 Jewels" added underneath "WATER 150m RESIST."
  • The 7002-700A is a 150m diver with a blue-and-red bezel. The 7002-700J, according to Shawn Taylor/shawn, is another variant -- "Japan only market version with '17 jewels' on dial, but with red/blue bezel."
  • The 7002-7039 seems to be the first "low-end" diver model that got its water resistance rating promoted to 200m. While the 150m 7002 divers have bi-directional bezels with 60 clicks (the traditional design), the new 200m 7002-7039 has a uni-directional locking bezel with 120 clicks. The dial says "DIVER'S 200m." The new features introduced in this diver (200m water resistance, uni-directional bezel with 120 clicks as well as the dial inscription) will carry on in the 7S26 models that succeed the 7002.

7S26

  • Production: 1996 - present
  • Movement: cal. 7S26
  • Description: 200m divers

7S26 gallery

Models:

Seiko is marketing so many styles of the 7S26 divers that it's hard to keep track of all the variations. But the basic 200m diver that replaced the 7002s maintain a similar look and feel to classic divers in the 6105-6306-6309-7002 lineage. The most commonly seen are the following models:

  • SKX007K (7S26-0020, round markers)
  • SKX007J (7S26-0020, same as SKX007K but with extra text on dial)
  • SKX009 (identical to the SKX007 except for a blue-and-red bezel)
  • SKX011J (7S26-0020, SKX007J styling, but has orange dial and gold letters on bezel)
  • SKX171 (7S26-7020?, has a different bezel design than the classic models)
  • SKX173 (7S26-0029, rectangular markers)
  • SKX175 (7S26-7029, like the SKX007 but with a blue-and-red bezel)
  • SKXA35 (7S26-0029, identical to the SKX173 except for a yellow-dial)
  • SKX779 (7S26-0350, new design -- thick case, scalloped bezel and redesigned dial)
  • SKX781 (7S26-0350, same as the SKX779 except it has an orange dial)

There are many other variations of the 7S26 divers that are less frequently seen. Some are 200m divers like the classic models, others are "sports divers" rated to 100m. The following list is by no means exhaustive:

  • SKX403J (titanium 200m diver, black dial, "Made in Japan" version, 7S26-0160)
  • SKX403K (titanium 200m diver, black dial, non-"Made in Japan" version, 7S26-0160)
  • SKX405 (titanium 200m diver, champagne-color dial, 7S26-0160?)
  • SKX013 & SKX015 (38mm mid-size 200m diver, black bezel & blue-and-red bezel)
  • SKX023 & SKX025 (38mm mid-size Submariner-style 100m diver, black & blue-and-red bezel)
  • SKX031 & SKX033 ("Sports 100m" diver, Submariner-style black & blue-and-red bezel, 7S26-0040?)
  • SKX021K (100m diver, white dial, 7S26-0050)
  • SKX421 (titanium 200m diver with "Tag Heuer-style bezel," black dial?)
  • SKX423 (titanium 200m diver with "Tag Heuer-style bezel," orange dial)
  • SKXA33 (new design variation of the 200m diver with integrated bracelet?)

(Not listed here are the ladies and some mid-size divers.)

Details:

The current crop of Seiko divers all use the cal. 7S26 movement, which has 21J and runs at 21,600 bph. It's a non-hacking movment like most traditional Seiko calibers and has a quickset day/date calendar system. (For an in-depth technical analysis of the 7S26 movement, see John Davis/ei8hthoms' review of the SKX779.)

Here are some of the differences among many of the popular variants:

  • The SKX007 and SKX173 are the standard models that are direct descendants of the 6105-6306-6309-7002 line of divers. The SKX007 is an Asian-market Seiko while the SKX173 is a N. American version. The SKX007 has round markers while the SKX173 has rectangular markers. The SKX173 uses a second hand similar to the 7002 divers. The second hand has a luminous dot located toward the end of the sweeping portion. On the SKX007, the dot is located on the elongated "back end" and the sweeping portion is painted white and has no lume.
  • At first glance, the SKX009 and SKX175 are identical to the SKX007 except they have blue-and-red bezels, but the differences between the two models are frequently the object of heated debate among some Seiko watch owners. One major difference, according to Ed Rader, is the color of the dials: The SKX175 has a dark gray dial and round markers (like that on an SKX007), while the SKX009 has a blue dial. But Bob Falfa says the SKX009 and SKX175 dials are identical in color; the difference is in the markings and country in which the models are marketed.
  • There has been extended discussion among Seiko diver collectors on the differences between SKX007J and SKX007K. The SKX007J has extra text on the dial that's not on the SKX007K -- "21 JEWELS" under "DIVER'S 200m" and in small lettering "Made in Japan" along bottom edge of dial below 6 o'clock. Some people have said the SKX007J is made in Japan and the SKX007K is made in Singapore and the Japan-made model seems to be better. Others argue there's no proof of the country of manufacture or of any difference in quality between the divers. Many people on the S&C Forum have concluded that there is only cosmetic but no real difference between the J and the K variations -- they are all great divers.

    In answer to the question, "What are the differences between SKX007J and SKX007K?," Seiko Japan said:

    "The watch ref.#SKX007J and SKX007K are completely same watch model. The shipping route is slightly different. We are not able to inform you of the details" (email from Seiko Japan Service Group, 10/28/02).

  • The SKX011J is identical to the SKX007J except it has an orange dial. The bezel insert also lettering and markers in gold instead of the customary silver.
  • The SKXA35 is identical to the SKX173 except it has a yellow dial.
  • The SKX779 and SKX781 are new designs that depart from the classic diver style. They have a thick scalloped bezel on a thick stainless steel case with pronounced curves. They also have a slight convex glass crystal. The dial and hands are radically different in style from the classic divers. Owners seem to all agree that the SKX779/781 cases are bombproof and the dial and hands glow like Chernobyl.

Except for the SKX779 and SKX781, the traditional-style divers all have similar if not identical cases. One small difference between the 7S26 divers and their predecessors is that the crown position on the 7S26 has moved to 3:45 o'clock instead of 4. All 200m divers have uni-directional locking bezels with 120-click graduations.

According to the Seiko Japan Service Group, here are the dates when the following models started production:

Watch model #Production started in
SKX007J1996
SKX007K1996
SKX011J1996
SKX1731996
SKX1751996
SKX779/7812000
SKXA352002

Here are some details about other variants of the 7S26 divers:

  • According to S&C Forum contributor Yap Kok Hung, the Seiko Titanium 200m diver SKX403 comes in 2 versions: "the Seiko Ti diver with the black dial (7S26-0160) is known as the SKX403K (non-Made in Japan version) and SKX403J (Made in Japan version with the jewel count and the words 'Made in Japan' on the dial)."

Details:

The 2205 divers were made in the early to late 1970's, though the exact production dates are unclear (the 2205 movement was produced as early as 1970). 2205 divers have the word "PROFESSIONAL" on the dial. Their hands are similar to the ones on the 6105 divers, except smaller. The divers come in small/ladies size (about 33mm) and are probably the earliest counterparts of the 150M full-size divers (like the 6105 and 6309). Variations include black dial and orange dials (orange dials are rare), and also black bezel as well as blue-and-red bezels. The 2205 is a high-beat movement that has 17J and runs at 28,800 bph. It is hand-windable but does not hack. The movement has a quickset date-only mechanism.

The 4205 divers came after the 2205's. They can be found in small/ladies size (about 33mm) as well as mid-size (37mm). Variations include black dial and orange dials (the orange dials are very rare). The bezel is bidirectional, with one-minute clicks. The divers are rated to 150M and has a slightly domed crystal. The 4205 movement runs at 21,600 bph and is hand-windable, but does not hack. It has a quickset date-only mechanism. According a poster on the S&C Forum, Coserv claims the production dates of the movement were from 1982 to 1987 (though these may not be exact).

The SKX001 and SKX005 were mid-size divers probably made in the late 90's but now discontinued. They have Tag-style steel bezels like the current SKX171 design and are rated to 200m like other 7S26 divers. There's not much info on these otherwise. There are pics of these divers in the gallery here.
