This gut shot is of a Seiko caliber 7002A from a vintage Scuba Diver’s model 7002-700J (case number).

From an article on Time Zone by Rob B:

Consulting the Seiko parts catalogs revealed that the cals 7002, 7005 7006 and 7009 are almost identical, sharing many parts in common. The main difference is in thickness, day/date features and jewelling. The 7005 is date only, the 7009 is a day/date and the 7002A is date only and has a different auto winding weight. Since this particular movement is a “date only”, then one concludes it started life as a 7005A, to be transfomed at a later date by whatever parts were to hand at the time…

Hey, I have this 7002A mov. in my ’96 SDS101 Diver and since it hasn’t worked in a few years was thinking about replacing the mov with something more modern. What would you suggest that will fit just right in the same size case? Thank you
