Archer,
This is very helpful for me as I just purchased my first vintage Speedster (145.022). I need to have a service as I don't know when the last was completed, and my local Omega certified watchmaker says I need to replace the crystal for him to guarantee the water resistance. The crystal isn't scratched, and I'm thinking I should just keep the current one Your thoughts? Is it normal to replace the crystal every time it is serviced? I'm wanting to keep the watch as original as possible, but I'm not even sure the crystal that is on it is the original (it is an Omega).
Thanks, Dave
