Help with a crystal that is driving me insane!

Submitted by GVP on January 8, 2013 - 4:37am

So ok I have two watches (one pictured below), both the same, both needed new crystals. I got two GS CO496-60 crystal, they fit perfect EXCEPT the damn dome doesn't appear deep enough and on both watches it pushes the centre second hand down and stops the watch running. ANyone know exactly what crystal these should take or where i could find two of them. this has been driving me nuts for a month or two now, any help appreciated.

Hi

One of them has a black 2590 stamped in the back, nothing else

Gary, try a CO496-70. It's listed in the GS catalog #200 as for the 2590 and is the same dimensions as the CO496-60 but in the illustration looks deeper. Sorry, I don't have any.

Here is your watch in an ad too, far right.

"Diamond Excellency", variant unknown from 1967.
