Overview
A complete calendar shown through an open dial
The Vacheron Constantin Traditionnelle Complete Calendar Openface, reference 4020T/000P-H038, in 950 platinum with an openface 18K gold dial for the brand's 270th anniversary, on a dark blue alligator strap. Self-winding calibre 2460 QCL/270 with a complete calendar and moon phase; 41 mm, 11.05 mm high, certified to the Hallmark of Geneva, limited to 370 pieces.
The reference 4020T/000P-H038 is Vacheron Constantin's Traditionnelle Complete Calendar Openface, made for the brand's 270th anniversary in a stated limited edition of 370 pieces. The case is 950 platinum, 41 mm across and 11.05 mm high, with the collection's stepped lugs, slim bezel and fluted case back. The silver-toned openface dial carries an 18K gold hand-guillochéd pattern in the anniversary Maltese-cross design, with day and month shown through apertures, a central hand-type date on a blued 18K gold hand shaped with a crescent, realistic 18K gold moons, dauphine hour and minute hands and applied hour-markers, against a railway-style minute track. It is worn on a dark blue alligator leather strap with a 950 platinum triple folding clasp.
The self-winding calibre 2460 QCL/270 combines day, month and date with a precision moon phase for a complete calendar, and carries a balance-stop function; the brand describes the bridges as finished with a côte unique treatment and a discreet anniversary signature. It measures 29 mm across and 5.4 mm high, with 308 parts and 27 jewels, running at 28,800 V.P.H. (4 Hz) for a stated 40-hour power reserve. The watch is certified to the Hallmark of Geneva, which the brand traces to 1886 as Geneva's own standard of finishing, now read as a mark of provenance and reliability.
For collectors
Vacheron Constantin lists a balance-stop function, which lets the movement be stopped so the time can be set precisely.
