Overview

About this reference

The Master Ultra Thin Q1142510 places a 39 mm rose-gold case, 9.2 mm thick, around a beige satin dial with applied markers. Its perpetual calendar brings the day, date, month, year and moon phase into a restrained surface, with a red security zone adding a precise point of contrast. A see-through caseback, pin buckle and 50 metres of water resistance complete a reference whose generous calendar display remains within the collection's slim, formal proportions.

Calibre 868 is an in-house automatic movement with a 70-hour power reserve. It measures 26 mm across and 4.72 mm high, contains 330 parts and 46 jewels, and uses a full rotor with hand-winding capability. Its 4 Hz oscillator drives the perpetual calendar functions, including the day, date, month, year and moon phase. The movement is finished to a haute-horlogerie grade and visible through the display back.
