Help With Crystal

New postby Marty101 » Sat Dec 27, 2014 12:51 am

Friends,is there a way to decipher the coded packets of plastic(maybe glass too)crystals? I have several that are a mystery to me;they have a letter/number code on each. Examples for GS "Flexo" are PMX323-7 or PMC570 and so on. And on... :?

I'm...flabbergasted. I just took it for granted that they were long gone and broke one of our basic tenets:do not assume. I was hoping a WW man out there had a chart or such. :oops:

The P series crystals date from the WW 2 era. Nowadays most watches using P series crystals are fitted with glass, it looks and wears better. Most watches today use "C" series crystals. The book for all these "c" crystals is still in print - you can buy them from any supply house.

The books for the "P" series crystals are very rare - most of them got thrown out in favor of glass assortments, or having your favorite material supplier cut them for you - like I do!

What does one do with the my, s, t, x series crystals, do they still have any use or are they obsolete?

Those are part of the "p" series and if they have not yellowed, are still useable, but its been years since I had need for one. Sell them to someone who does preWW2 watches!
