Finding The correct replacement crystal

How to add images to myBulova.com forums & comments

Submitted by ralwan on

I have a nice Bulova watch maybe an Ambassador and I am looking for a crystal for it.  I took measurements and they are as follows (mm)

Greatest possible 23.6 x 21.7

Measured from the corners 21.8 x 17.7  

I scoured the GS catalog and cannot find an exact match.  Any help or advice would be welcomed.

Hi Ralwan. That looks like a 1940's "Minute Man" bezel. If it is, the G-S CMY305-10 crystal should fit it. It measures 23.4 X 21.4 mm. Keep in mind that I don't give a warranty with my advice. Take it at your own risk.

I'm old and feeble, but I guess I'm still good for something. Thanks for letting us know it fit.
