Overview
A perpetual calendar kept ultra-thin
The Vacheron Constantin Traditionnelle Perpetual Calendar Ultra-Thin, reference 4300T/000G-H106, in 18K white gold with a silver-toned dial and pink gold hands and hour-markers, on an alligator leather strap. Self-winding calibre 1120 QP with day, month, leap year and moon phase shown by hands; 36.5 mm, 8.43 mm high, certified to the Hallmark of Geneva.
Vacheron Constantin's Traditionnelle Perpetual Calendar Ultra-Thin is built across this family in 18K white or pink gold. The brand describes the case as keeping to the Traditionnelle collection's usual look: round with lugs stepped away from the case, a slim bezel and a case back cut with fluting; the dial's minute track is railway-style, read against dauphine-shaped hour and minute hands. The case measures 36.5 mm across and 8.43 mm high. The silver-toned dial carries a full perpetual calendar -- hours, minutes, a hand-type day and month, a leap-year counter running to 48 months, and what the brand calls a precision moon phase -- closed on an alligator leather strap by an Ardillon buckle in the case's own metal.
Inside is the automatic calibre 1120 QP, Vacheron Constantin's ultra-thin self-winding 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 movement carries the Hallmark of Geneva. The brand's own account traces that mark back to 1886, when the Republic and Canton of Geneva adopted it as a guarantee of quality for watches finished to its own standard, and says today it stands for provenance, sound workmanship and reliability rather than any single technical figure.
For collectors
The five references built on this case and calibre differ in metal, dial finish and hand colour -- including whether the hands and hour-markers are toned to match the case or set against it -- worth comparing directly rather than assuming beyond the shared case and movement.
