Overview

About this reference

The Master Control Q4148421 uses a 40 mm stainless-steel case, 10.95 mm thick, to frame a grey sunburst dial with applied markers. Rather than a conventional date aperture, its calendar is represented by a central jumping hand, joined by the hour, minute and moon-phase displays. The see-through back exposes the mechanical depth behind the composed dial, while a deployant clasp and 50 metres of water resistance preserve the reference's polished, versatile character.

Automatic Calibre 866 is made in-house and stores 70 hours of power in a single barrel. Its 344 parts include 34 jewels, and the 6.15 mm-high movement operates at 4 Hz with a silicon escapement and full rotor. It drives the day, date, month, moon phase, jumping date and small seconds. Fine finishing is visible through the display back, while the cased watch undergoes 1000 Hours Control.
