MB&F Horological Machine No. 2

About this reference

The MB&F Horological Machine No. 2 (HM2) Sapphire Vision (SV) in titanium was produced between 2008 and 2011 as part of the brand’s early experimental era. Collectors target this reference for its complex architectural case, which features a transparent sapphire crystal top plate secured by a titanium base and a distinctive rubber gasket system. The watch utilizes the HM2 engine, a Jean-Marc Wiederrecht-designed movement built on a Girard-Perregaux base, featuring the world’s first mechanical movement combining instantaneous jumping hours, concentric retrograde minutes, retrograde date, and a bi-hemisphere moon phase. This specific variant was limited to 25 pieces, contributing to its scarcity. On the secondary market, the HM2 SV titanium typically trades in the $50,000 to $80,000 range depending on condition and provenance. A notable production detail is the use of over 100 components in the case construction alone to ensure water resistance despite the modular sapphire design.
