I don't think this 10BPAC had ever been serviced before me and it needs a new mainspring (still can't source one) Added the 50's Flex-let myself. I love this little sucker.

Your Bulova 23 'A' looks to be in very nice condition. It is my understanding that the lifetime mainspring in these requires a barrel complete to be purchased instead of just the mainspring; but perhaps someone with a better knowledge of these can clarify that.

From what little research I've done on this mvmnt, I think you are correct. No manual that I've seen indicates an interchangeable.

I assume it's the ms-It will keep -30 to -60s/day as long as it's on the wrist with the rotor swinging. Take it off and lay it down, it stops between 3-4 hrs later.

Oh, and that should be 28mm crystal.
Whoops.

Sweet! 1956 Bulova 23 "A". One of my personal favorites from the 23 series. I'm actually wearing my '56 23A as I type this .

These movts have sealed barrels if memory serves, so you'd have to open it and measure the mainspring and just get one that is identical if possible or close. It is derived from the 10BOAC.
