8.1mm Ultra-thin Vacheron Constantin Perpetual Calendar

The Vacheron Constantin Overseas Ultra-Thin Perpetual Calendar is available in either 18K 5N pink gold or 18K white gold, with new dial colorways lending distinct visual personalities to the same set of complications.

Let us begin with the dial. The 18K 5N pink gold model creates an immediate impression of seamless cohesion; the case, bracelet, and sunburst satin-finished dial all share matching pink gold tones, extending even to the moon-phase disc and the lunar motif. In contrast, the 18K white gold version pairs the metal with a rich burgundy-red lacquered dial, creating a striking color contrast. Subtle variations in texture emerge within the same color palette: the sunburst pattern radiates outward from the center of the dial, while the minute track features a velvety finish.

The blue minute track encircling the dial’s periphery is a particularly ingenious touch. It introduces a cool-toned visual accent that echoes the blue Super-LumiNova® luminescent coating on the hour markers and hands. This detail infuses the timepiece—otherwise a classic example of high-end watchmaking in precious metal—with the modern aesthetic characteristic of the Overseas collection. The perpetual calendar indications are distributed across several sub-dials: the date and day displays flank the center, the moon-phase display sits at 6 o'clock, and a sub-dial at 12 o'clock tracks both the month and the leap-year cycle. While the moon phase is not the core function of a perpetual calendar, it serves as a vital visual focal point. It reminds the wearer that the time recorded by the watch transcends mere calendar digits; whereas dates, months, and leap years are constructs of human-made calendars, the waxing and waning of the moon reflect actual astronomical cycles.

The watch features a 41.5 mm diameter and a case thickness of just 8.1 mm. This remarkably slender profile is largely due to the internal Calibre 1120 QP/1 movement, which measures only 4.05 mm in thickness. Buy top TAG Heuer clone watches online, buy replica watches at twatchclone.
