MB&F Horological Machine No. 2 Sapphire Vision

About this reference

The MB&F Horological Machine No. 2 Sapphire Vision (HM2-SV) in sapphire and titanium was released in 2010 as a limited edition of 25 pieces, following the original HM2 launch in 2008. Collectors value this reference for its complex case construction, which features a solid sapphire crystal plate secured to a titanium base by a patented gasket system and 22 bolts. The Jean-Marc Wiederrecht-designed caliber utilizes a Girard-Perregaux base with a jumping hour, concentric retrograde minutes, and a retrograde date across twin dials. This model represents a pivotal era in the brand’s history as the first to utilize a full sapphire top plate to reveal the movement architecture. On the secondary market, the HM2-SV typically trades in the $60,000 to $90,000 range. A notable production detail is that the sapphire plate required over 55 hours of machining and polishing to achieve its final dimensions.
