Traditionnelle Complete Calendar Openface White Gold

In Context

At 41 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 10.72 mm thick it is about average for a modern wristwatch. 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. 40 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.

4020T/000G-B655 stands on its own in this catalogue — no other reference here shares its base number. It pairs a see-through dial with a white gold case.

Calibre 2460 QCL/2 is a self-winding movement with a total of 312 components. It is based on the 2450, the first in-house self-winding movement by Vacheron Constantin. It beats at 28,800 bph and has a 40 hour power reserve. In addition to its triple calendar indications, it features a precision moon phase display requiring only one correction every 122 years. This version of the 2460 QCL was introduced in 2021.

2 other watches in the library run the Vacheron Constantin 2460 QCL/2.
