Parts Compatibility Note

We recommend our CT208 CT209 CT228 Crowns for this case and our CT237 MM bezel. If you are using a flat insert for your build (as oem MM) our CT099 Sapphire is good. If you are using a sloping insert our CT119 Sapphire is good. Of course you are free to choose any others manufacturers parts to complete your build and they should in theory fit but we cannot be responsible if you are disappointed in the event you end up with a frankenwatch look or the bezel function/feel is not as you expected.

A Front Loading MM Conversion Case Set with NO back. Drilled Lugs. Polished/Brushed finish. Most SKX007 parts will fit this case – Dial, Chapter Ring, Crystal, Crystal Gasket, Bezel, Bezel Insert.
This is our tribute to the classic MM case WITH A TWIST. It is NOT and was never intended to be a 100% exact copy of the oem case. We believe we achieved a good balance between the oem look and our unique conversion case.
We strongly advise that the assembly of this case is more suited to the experienced watch building enthusiast – Please fully read the Instructions before purchase


Oem and aftermarket MM SEL bracelets will not fit this case. This superb case was designed for straps and not MM SEL metal bracelets. This case is specifically designed to suit the NH Grey Movement Holder – The thicker black movement holder i.e. 7S26 SKX007 will not fit
Water Resistance – As oem*

*This case was tested to 300M during development and subsequent testing of actual production cases
