Hello

I just got a vintage Monza 150.501 and in need of new crystal. Any watchmaker/dealer here or anyone know where I can source a correct one? I believe 1156 uses the same crystal.

Thank you

Are there various crystals that are interchangeable? I've seen the 150.501 with a dome-like crystal and others with a flat mineral crystal.

 

I personally do not know. I just need a replacement. Help!
