I can attest to the fact (as a 7548 owner) that the case back has 1 dimple indicate the next probable date to change the battery when newly purchased. I purchased mine (New) March 1985 the serial number from the Navy exchange in Japan. Serial number 41xxx2 (1984 January). My dimple is stamped 1 hash tag back from the 1987 marker on the caseback. I am 58 years old and still own it. repairing this watch was a logistical nightmare without the internet. The first to go is the ripping of the holes in the rubber strap and the "battery" was special back then too........Still running perfect and on its 4th battery change

Absolute belter 🔥👍🐟

It’s so insane that you have to pull the case apart like that to change a battery. That’s why these really should have stayed automatic like the grandfather.

Pure poetry.

[@neelsengupta662]

So, does that mean this is a really rare watch, if you haven't serviced many? Even though it was in a Bond film??

[@adrianhargreaves2854]

Hi Spencer What are those 2 small screws for on the underside of the case in between the lugs? Cheers

[@Cristian0702]

There is a spring that presses a ball to actuate the bezel clicks

[@adrianhargreaves2854]

@@Cristian0702 thanks. I’ve seen them on a few videos and always wondered 👍

[@petemoss8245]

@@Cristian0702 ....Yes! another replacement item that was extremely hard to source without Seiko access or the internet back in the day.

[@petemoss8245]

Another point is that even the 2 screws holding the battery spring bar are expensive to replace too. Don't loose them.

I believe Seiko thought that they had made a good watch , But in hindsight it was much more .

[@bombora69WA]

What happened to the movement holding O-ring?
