My green Gruen needs a new crystal to look right. I can find it in the Gruen's crystal chart in Mike's Green book but ordering it from the factory is a difficult step. Rolling Eyes

How can I translate this information to a crystal I can look for?

Measuring it is helpful when you don't have a part number.

I do have some part numbers though from crystal catalogs for a 157 / 8.
Watchcraft
(delta)2A260 This one was shown with the 8W specifically.
9A245 This one says 157/8 with no W in the catalog.
I'm not sure of the diffs between these 2. Could be the double-thick style perhaps?

The (delta) in the crystal book means...
Denotes Watch-Craft Regular Glass and Rock-Craft glass crystal. For Rock-craft include RC before the number. The 157/8W is available in both.

I searched and found the measurements for this crystal to be 26.0 x 17.3

If you really get stuck, there is always crystal houses that fit them at a good price.

I use a guy that always has these Quadron crystals in stock. His name is Ron, and a super good source. I own 9-10 Quadrons, and if you can send me a picture of your crystal, and if I have one in stock, you can have it!

People you thought were your best friends will stab you in the back to your face!

Love them anyway.

That green glass can't be original, can it? Must be a freak of fashion a while ago.

Thanx. I will PM you! My exhausting internet search gave zero results.

I don't know why anybody thought these were a good idea, but you see quite a few colored aftermarket crystals floating around eBay. They sure don't make a watch any easier to read.
