I just bought a 1959 Omega Seachero 2990-1 which has an Omega-signed original crystal but as you can see there is a deep scratch at the 12 o’clock position. Picture attached. Any leads on NOS replacements? It’s a 36mm case. Thanks!
800 grit sand paper (wet), then 2,000 grit sand paper (wet), then Polywatch. The whole process should take you about 2 minutes and the Plexi is like new again.
You're welcome.
