To celebrate the opening of the MB&F LAB in Silicon Valley with retail partner Stephen Silver, the LM Perpetual EVO series is joined by a limited edition of 18 pieces in 18 karat rose gold with an ocean blue dial plate, the only precious metal version of this model. The case profile emphasizes openness and clarity. A special shock-absorbing system was created for the Evo making it the most robust timepiece from MB&F. Stephen McDonnell designed this movement with a "mechanical processor" consisting of a multi disk system. At its core, it uses a 28 day month system and adds additional days as required by a specific month. This removes the possibility of the date jumping incorrectly. With an integrated rubber strap for the smoothest wearing experience of any MB&F Machine ever, t he LM Perpetual EVO is a watch for life.
