Perpetual Calendar 5050 Rose Gold / Silver Roman

In Context

At 37.2 mm it sits just under the modern norm — the band that suits the widest spread of wrists. 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. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.

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 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

5050R-001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver sunburst dial with a rose gold case. Introduced in 1995. Beyond the time it carries a perpetual calendar.

Self-winding movement with perpetual calendar and moonphase; retrograde date hand. Succeeded by 324 S QR.
