Premier Heritage B19 Datora 42 Perpetual Calendar 140th Anniversary

In Context

At 42 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. 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. 100 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. 96 hours of reserve puts it well past a weekend — several days off the wrist and it is still going. At 28,800 vph the seconds hand advances 8 times a second.

RB19401A1B1P1 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black matte dial with a red gold case. It was a limited edition. Beyond the time it carries a perpetual calendar.

Self-winding movement with chronograph, perpetual calendar and moon phase indication, launched in 2024.
