The MB&F Horological Machine Number 2 has enjoyed a really rich life. The ‘wrist rectangle’ is now going into its final limited edition production with two new models. These are the HM2 Black SV and Red SV. “SV” stands for Sapphire Vision, and are related to the original HM2 Sapphire Vision watch that I discussed here – and had a real-life image of here. The whole point of the Sapphire Vision watch was the massive sapphire crystal that made up the front plate of the piece. The crystals were ungodly expensive to make and a tortuous trial in patience as many would break in the manufacturing process. One you make the crystal and it is stable, they are relatively strong, but the weakness is in making them.

Now MB&F revisits the SV concept with these two new, slightly more showy models. I am not going to go into full technical specs about the piece – because I have already done that, and they are below. The movement is the sweet looking caliber specially designed for the HM2 with 349 parts. It has a centrally mounted “battle axe” automatic rotor (that is in 22k gold), and displays the time (with separate hour and minute indicators), along with a moon phase indicator and the date.

The HM2 Black SV is in a black PVD coated titanium case with a green gasket. How neat looking is that? To match the green color, MB&F PVD coated the 22k gold rotor in green. The HM2 Red SV is in 18k red gold, with a black gasket. As in the Black SV model, the gold rotor is PVD coated black to match the gasket. Both of these models are very handsome and reassures collectors that the Sapphire Vision look and concept was a fantastic idea. MB&F is very open on what a pain in the ass the sapphire crystals are. They are said to be incredible complex, requiring over 100 components to make them, and requiring over 55 hours for each large sapphire plate to be cut. Of course, all the holes (for the screws) and fine details are the hardest to do.

How many of these “Final Edition MB&F HM2 models will be made? Just 18 pieces for the HM2 Black SV and another 18 pieces for the Red SV. Prices are $98,000 each. What to expect next? You guessed it, special versions of the HM4.
