Thank you so much! Is there a place I can go to find out what glass go with which reference? I have just bought a large stock of Longines, Tissot and Omega vintage spares.

Archer is an Omega certified watchmaker, so he has access to the private Omega documentation, which isn't available to the public.

So unfortunately the rest of us are stuck googling 😀

Amongst the vintage spares (numbering over 100,000 pieces) I bought, there are a LOT of technical manuals and information for Longines. Tissot and Omega. There are also some Rado and Certina spares that I saw and I'm sure some other stuff! Lucky me!
