Part Number for a Crystal

Hamtramck Stan's picture

I am wondering if there is a part number for the crystal to a 1948 Arnold? Please excuse my ignorance as I am still green as a granny smith apple when it comes to vintage Bulovas!

Hi Hamtramck Stan. A G-S CMT346-30 crystal is what you need for a 1948 Arnold. G-S still makes those so it shouldn't be too hard to find one.

Hi Hamtracmck Stan

If you prefer Glass over plastic for what I think is a better vintage look and better optics, here are a few

Perfit   MB239/6

B&B    MT2398/203

Fulton  M2 239F

Federal  MT15 239/204

Watchcraft  7MC 239

Sorry it took a long time to reply, but Thx for the additional numbers. Yes, I am looking to install a glass crystal, and these numbers help!

Veritas123, which would be the best glass crystal from the listed crystals (optics/fit)? Also, how can I obtain one from you?

I would say that the optics are all about the same on glass crystals when you compare standard thickness types to each other. With the high profile and cylinder styles you start to get some distortion.

As for fit, that would depend on the watch case to some extent and the crystal manufacturer . Also the age of the watch.  Most glass crystals require some fitting. I have a fitting guide that can help you if you don't use a watch maker for your work.

As far as purchasig from me . Send me a Private Message and I can tell you what I have and how to purchase.

Well, two things... First, my apologies for I am stumped at how to send a personal message (it has to be be obvious, but I have not figured it out).

Second, I had a BB MT2398/203 that doesn't have enough crown (too flat) so that it rocks along the horizontal centerline (9 to 3). I used GS cement, and the crystal stays in, bit still rocks when pushed at the top or bottom of the crystal.

I need some help in identifying the proper G S crystal for my 1950 Director. The one listed here under vintage catalogs is apparently for a earlier model. The closeset I get is GS CMC401. Can anyone verify?

Thanks

Hi Ray

I think a CMC325 will work.

I can verify that the G-S CMC325 is the correct crystal for the 1950 Director.

Can glass crystals with light scratches be ground out? Or is it better to just but a new Crystal?

I'm sure you can do it with the proper equipment but for a $15 to $20 crystal I don't think it is worth the time and energy.

Some people like a challange  but not me.

Hope that helps you.
