Grande Reverso Calendar

In Context

At 29.9 mm it is small by current standards, in the range most wristwatches occupied before cases began growing through the 1990s. At 10.2 mm thick it is about average for a modern wristwatch. The case back is closed, so the movement stays out of sight, 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 is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 45 hours of reserve carries it overnight, but not through a weekend in a drawer. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

3758420 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver guilloche dial with a stainless steel case.

Mechanical manually-wound movement, 231 parts, 21,600 vibrations per hour, 45-hour power-reserve. Indicators for hour, minute, day, month, date, moon phases.
