The Master Eight Days Perpetual is a perpetual calendar wristwatch with an 8-day power reserve. Two barrels, 28,800 vibrations per hour and a variable inertia balance wheel. All the perpetual calendar functions (mechanically programmed until 2100) are activated by a single corrector. The dial is easy to read and the display of functions is well balanced. Complete year indication. Requiring two months' work, each movement part has been designed, openworked and decorated to create an exceptional piece when combined.
