Need to locate Crystal for my noobmariner.

Would like to find one with etched cornet

Hi mate,

I am selling am GMT IIc case here:

The crystal is flawless and has the etched crown at 6.

I am not totally sure that it will fit the Noobmariner - maybe the experts can chime in?

Cheers,

W.

When looking for a replacement crystal, list the case number or exact crystal size...overall OD, OD under the top edge if applicable, thickness, and date magnifier offset from center.

Most replica crystals are straight sided with no step.

I also have a noob with a broken crystal, case number F520117. This case has a sapphire crystal with a ledge at the top similar to genuine but a different size so a genuine spec crystal will not work. I scratch tested the crystal since it was broken anyway...it is sapphire for sure.

I have been looking for a replacement for 2 years with no luck. :cry2:

The F520117 crystal is 30.45mm overall OD

The step under the crystal top edge where the gasket seals is 29.0mm.

The crystal is 2.0mm thick with beveled top edge.

The center of the date mag is 9.0mm from the dial center.
