Master Gyrotourbillon 1 Platinum / Baguette / Aventurine

In Context

At 43 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 15.96 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 is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 192 hours of reserve puts it well past a weekend — several days off the wrist and it is still going. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

6006406 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue dial with a platinum case.
