Subject: Inquiry about Seiko divers chronology

Hello!

...

I am looking for specific production dates for the following diver models (date when Seiko started producing the model and date when Seiko ended the series) and any other historical information you may be able to provide for them:

62MAS (6217-8000T)

6215-010

6105-8000
6105-8110
6105-8119

6306-7001

6309-7040
6309-7049
6309-7290
6309-729A

7002-7000
7002-7039

And specific dates of when these current divers were introduced (I believe they are all 7S26-0020):

SKX007J
SKX007K
SKX011J
SKX173
SKX175
SKXA35

Your help is greatly appreciated!

Sincerely,

-Kevin Chan

Dear Mr. Chan,

Thank you for your e-mail message dated Oct.25. We appreciate your patronage of our products. Although we have checked all our catalogs and documents, unfortunately we have been unable to find out the exact period when each watch was produced and used to be sold. Instead, we can inform you of the approximate period when the movement caliber of each watch was produced. The watch that has the movement cal. was produced during the period. We hope it will be of some help to you.

Regarding the other information of the listed watches, as you can probably appreciate, most of the production records concerning that period of time have been lost and we are not able to give you. We regret that due to this lack of the information we cannot provide you with any further information about this matter.

Neverthless, thank you for your interest in our products.

Sincerely yours,
