Annual Calendar 5450 Advanced Research

In Context

At 39 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. 45 hours of reserve carries it overnight, but not through a weekend in a drawer. At 28,800 vph the seconds hand advances 8 times a second.

5450P stands on its own in this catalogue — no other reference here shares its base number. It pairs a pink dial with a platinum case. It was a limited edition. Beyond the time it carries an annual calendar.

Annual calendar movement with day and month by hands, date in an aperture, moonphase and power reserve indicator. Gyromax balance.
