Overview
The Vacheron Constantin Traditionnelle Complete Calendar Openface reference 4020T/000R-B654 unites a fully openworked dial with a complete calendar complication, allowing the movement architecture and the calendar mechanism to be read simultaneously. Housed in a 41 mm 18k pink gold case, it represents one of the more architecturally ambitious expressions within the long-running Traditionnelle collection. The calibre 2460 QCL/2 drives the moonphase, date, day, and month indications while remaining fully visible through the skeletonized display.
History
The Traditionnelle line has long served as Vacheron Constantin's standard-bearer for classical horology, drawing on the manufacture's Geneva heritage and its adherence to the Hallmark of Geneva quality standard. The Complete Calendar Openface variant, introduced in 2017, extended that tradition by combining the openworking craft — historically a prestige complication in its own right — with the practical utility of a complete calendar. The reference sits within a broader family of Traditionnelle complications that demonstrate the manufacture's capacity to layer horological functions without sacrificing legibility or finishing quality.
Notable points
- The calibre 2460 QCL/2 is a manufacture movement that simultaneously displays moonphase, date, day of the week, and month — a full suite of calendar indications on a single dial.
- Openworking (squelettage) on a calendar watch is technically demanding, as the bridges and plates must be shaped to expose the movement while still supporting the calendar mechanism's multiple levers and discs.
- The 41 mm pink gold case follows the Traditionnelle collection's characteristic round, stepped-bezel profile, with proportions suited to both formal and refined casual wear.
- The reference carries the Hallmark of Geneva (Poinçon de Genève), a certification requiring strict standards of finishing, adjustment, and movement decoration beyond standard Swiss manufacture criteria.
- Introduced in 2017, the reference remains in production, reflecting Vacheron Constantin's practice of maintaining complex dress-watch references as long-term catalogue anchors rather than short-run novelties.
