Overview

About this reference

The Master Control Q4138480 presents the 40 mm, 12.05 mm stainless-steel case used by this calendar chronograph line, with a grey sunburst dial and applied markers. Its pushers open onto a display of chronograph seconds and a 30-minute counter, while the pulsometer and complete day, date, month and moon-phase calendar occupy the remaining indications. The round case, see-through back and deployant clasp keep the construction balanced, with 50 metres of water resistance.

Calibre 759 is an in-house automatic chronograph movement with a 25.6 mm diameter, 6.85 mm height and 65-hour reserve. It has 367 parts and 36 jewels, operates at 4 Hz and winds through a full rotor. A column wheel and vertical clutch control the chronograph, while Cotes de Geneve finishing is visible through the caseback. The movement also drives the day, date, month, moon phase and small seconds.
