This watch just came in from one of our members to have a new glass crystal made. The existing crystal appears to be a GS PKH acrylic crystal with a hole drilled in the middle!

First I'll select an over sized convex blank. 55mm will need to be reduced to 42.75mm. The inside center clearance will be reduced from 7.2mm to about 5mm which should be fine.

A perfect fit and looks as original.

Oh wait! I forgot to put a hole in the middle!

looks a lot better now.only one drawback.now you have to open the front to set the time.lol...

Victor,

That's why GS crystals are more popular than mine ....they're drillable!

William

A beautiful job.

Convenient hole for setting time also a passage for your ant collection.
