Vacheron Constantin Traditionnelle Style Full Calendar Automatic Mechanical Watch 41mm Moon Phase Design

Vacheron Constantin Traditionnelle series “cycle of time” full calendar wristwatch, reference 4010T/O00R-B344/B740/B345.

Case:
Case diameter 41mm, thickness 10.7mm. The watch features a stepped round case with matching lugs and a recessed caseback. The surfaces are finely polished, creating a refined and elegant texture.

Dial:
The dial includes a railroad-style minute track and feuille-style (leaf-shaped) hour and minute hands. The signature calendar display is preserved, with weekday and month windows symmetrically positioned on both sides of the dial.

A peripheral date scale runs along the outer edge of the dial, indicated by a slender black crescent hand for easy reading.

At 6 o’clock, the moon phase display provides a clear and visually balanced focal point, combining mechanical complexity with elegant aesthetics.

Movement:
Based on the Citizen 9015, an independently developed 2460 QCL/1-style automatic integrated movement is used. Development took two years with multiple refinements to movement parameters and component upgrades to achieve a high-precision configuration.

The overall design emphasizes classical elegance and mechanical artistry.
