The Vacheron Constantin Traditionnelle Perpetual Calendar Ultra-Thin is a family of 36.5 mm watches built around the self-winding calibre 1120 QP. Reference 4300T/000R-H107 is the pink-gold, silver-toned-dial configuration; references 4305T/000R-B947 and 4305T/000G-B948 add gem-set bezels and differ in metal, dial, and strap details. The manufacturer lists a 4.05 mm-thick movement and a 40-hour power reserve. These are published specifications, not independent test results.
What the name refers to
“Traditionnelle Perpetual Calendar Ultra-Thin” identifies a Vacheron Constantin watch model family, not one single appearance. The exact reference number matters: 4300T/000R-H107 is the standard-bezel pink-gold configuration, while the 4305T references have gem-set bezels and distinct dial and strap specifications.
The Canadian product page identifies the 4300T/000R-H107 as an 18K 5N pink-gold watch with a silver-toned dial. Vacheron Constantin’s official pages list prices as “on request”; they do not establish current stock or local pricing.
How the perpetual calendar works
Calendar and moon-phase indications
Calibre 1120 QP drives a hand-type perpetual calendar with day and month indications, a leap-year indication shown on a 48-month counter, and a moon phase. Vacheron Constantin describes the calendar as following the four-year Gregorian cycle and requiring no correction before 2100. That is the manufacturer’s stated horizon, not a claim that the watch never needs adjustment under every circumstance.
