Master Grande Tradition Tourbillon Cylindrique Quantième Perpétuel Platinum - Diamond / Blue

In Context

At 42 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 13.27 mm it is a tall case, and it will catch on a cuff. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse. 50 m covers rain and hand-washing comfortably; it is not a watch to swim in.

The movement winds itself from the motion of your wrist. 48 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

Q5246508 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue dial with a platinum case. Beyond the time it carries a tourbillon.

Mechanical automatic winding movement, 431 parts, 28,800 vibrations per hour, 45-hour power-reserve. Indications: hour, minute, flying tourbillon fitted with a cylindrical spring, seconds indication on the flying tourbillon, perpetual calendar: day, month, date, 4-digit year, moon phases.
