MB&F HM2-SV. Special sapphire version displays its micro-mechanics.

Hamilton ODC X-02

MB&F HM2-SV

This is the “Sapphire Vision” version of MB&F`s Horological Machine No. 2

The main difference is the substitution of the metal front plate of the watch for a large 3.6mm thick sapphire crystal so that a view of the entire movement can be appreciated.

Crystals of this size are notoriously difficult to create, the cutting alone takes 55 hours and quite a few break in the cutting and drilling stages, this could well be why this is such a limited edition watch with only 25 being produced.

The dial on the left displays the date as well as moon phase indicator. The right one a jumping hour display and retrograde minute display.
