Need help with figuring out what size batteries (2) this watch uses!  A reference to a tech or user manual would be great!  Thank You!

Cant help Mike. Good find though. I’ve had some but the screens never work properly.

Thought id better add a photo

That’s the one!  I actually found two of them… I think they might hold a 397, that’s according to my measurement!  Thank you!

Hi Mike….I have the same watch and the tech manual somewhere. Makes the watch running again is almost impossible due the dead of the lcd itself…and panel spares are no longer available.
I have tried to rechearge the panel (as the manual suggest) using 1.5v and a copper piece over the panel,some dark blue digits appear but nothing more…
Mine is NOS,so no corrosion but i repeat that the problem is only the lcd itself
