Seiko 7S26 glass measurement

[Nednico]

Hello!

I have to find a glass for a Seiko but I don't have the old model, it has been delivered to me with no glass.

How do I should mesure the diameter and height?

I have the old gasket on place, should I mesure with the gasket on or without it?

Thanks for your precious answer.

Not sure who has one to be honest. You can call GS directly and they may be able to help you. I contacted them about my Sicura Satellite. They did't have that info on file, but they may with a Seiko branded watch, especially if you have the manufacturers part number. Their customer service was excellent. They won't sell to you, but they can get you a part number and you can go from there. Their phone number is at the top right on the first page.

It's a flat mineral crystal, 1.5mm thick. Size is measured with vernier calipers with gasket in. Link given above tells Ø 30.5mm.
