Help with Bulova Astronaut battery replacement

Paging @Canuck .......... Could Mr Canuck call the front desk please.

Doug is probably in bed for a while but the gracious Gentleman has helped me, so this is straight from Canuck.
Pardon the clumsy photo, my Mac does not get along with the Word format I have saved. Hat's off to Canuck for his tremendous help and patience with putz's like me.

Good work Jimbo.
🤜🤛
I like it when a team works together.

It's an honor to be on this team.
Jiminoz and Canuck not only work the hardest to help, they also possess unrivaled skills and knowledge in my book (I'm the waterboy)!

@Canuck is definitely the Leader for this inquiry. Good luck!

It would appear that you have an Accu-Cell. There isn’t really a substitute available for the cupped ring you are missing. But you should be able to buy a complete Accu-Cell, and thereafter, when the battery dies, the components other than the cell can be re-used if you simply replace the dead cell, and put the components back together. But don’t lose a part. Not every Accutron requires that you use the Accu-Cell. Many of them will run fine with a 1.55-volt Renata 395, or equivalent. Have you tried running the watch using just the 1.55-volt cell? Remember, with Accutrons, the PLUS side is inserted DOWN since these are a POSITIVE GROUND device.
