I’m seeking a steel crown for the below Lemania. I believe the same crowns were used across 35mm waterproof Lemania, Omega, and Tissot 27ch models. Open to very similar generic or other replacements too.

Specifications (open to similar sizes as well)
Diameter: 6.3mm
Thickness: 2.8mm
Tube (outer diameter): 2.5mm
Stem: 1.0mm (tap 9)

Correct crown style:
