Overview
A perpetual calendar built into the Overseas
The Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin, reference 4300V/220R-H144, in 18K pink gold with a golden-lacquered dial and a moon phase against a starry sky, on the pink gold bracelet. Self-winding calibre 1120 QP with a hand-read perpetual calendar and moon phase; 41.5 mm, 8.1 mm high, certified to the Hallmark of Geneva.
This execution is the same Overseas Perpetual Calendar Ultra-Thin case and calibre 1120 QP movement as the white gold reference, in 18K pink gold with a golden-lacquered dial rather than burgundy; the moon-phase display and its starry sky are unchanged, and the counters here are snailed rather than plain white. The bracelet and its triple folding clasp are pink gold, and the two rubber straps supplied are dark blue and white rather than red and white.
The reference 4300V/220G is Vacheron Constantin's Overseas Perpetual Calendar Ultra-Thin, offered in 18K white and 18K pink gold with several dial colours, which the brand's page pairs a fine-watchmaking complication with the collection's sport-inspired case. The case is 41.5 mm across and 8.1 mm high, water-resistant to 50 m, with a transparent sapphire case back and an antimagnetic marking on it. Each dial carries a sunburst-finished centre and a velvet-textured minute track, a moon-phase display against a starry sky rendered in 18K gold with two gold moons; the hour-markers and hands are 18K gold, picked out in blue SuperLuminova®. The bracelet's links are shaped, on the brand's own account, to show the Maltese cross.
The self-winding calibre 1120 QP is Vacheron Constantin's ultra-thin base fitted with a perpetual calendar module: 29.6 mm across, 4.05 mm high, 276 parts and 36 jewels, running at 19,800 V.P.H. (2.75 Hz) with a stated 40-hour power reserve. The calendar is read entirely by hands -- day, month and a leap-year counter running to 48 months -- and the page states the display will read the correct date until the year 2100. The movement is certified to the Hallmark of Geneva; the brand's own account traces the mark to 1886, when the Republic and Canton of Geneva adopted it as their standard, tying it today to provenance and workmanship rather than one technical figure. The bracelet, closed by its own triple folding clasp in the case metal, can be swapped for two rubber straps supplied to match the dial, using a spare Ardillon buckle in the case metal.
For collectors
The page states this calendar will read correctly until 2100 -- a specific claim about the leap-year mechanism's range worth noting alongside the 48-month counter the Caliber tab names for it.
