Overview
Day, date and power reserve by hand
The Vacheron Constantin Fiftysix Day-Date, reference 4400E/000R-B436, in 18K pink gold with a silver-toned dial and a brown alligator strap. Self-winding calibre 2475 SC/2 with hand-shown day, date and power reserve; 40 mm, 11.6 mm high, certified to the Hallmark of Geneva.
The reference 4400E/000R-B436 is Vacheron Constantin's Fiftysix Day-Date in 18K pink gold; the brand ties the case's lug shape to the Maltese cross and describes the reference as honouring a model from 1956. The crown is integrated into the case, and the case back is sapphire glass. The case measures 40 mm across and 11.6 mm high, water-resistant to 30 m. The double-finished silver-toned dial has an opaline centre and a sunburst satin exterior, with snailed day and date counters, 18K gold baton-type hour and minute hands, and 18K gold hour-markers and Arabic numerals, the hands and markers highlighted in blue SuperLuminova®. It is worn on a brown alligator leather strap, closed by an 18K pink gold Ardillon buckle.
The self-winding calibre 2475 SC/2 shows the day and date by hand on the dial alongside a power reserve indicator: 26.2 mm across, 5.7 mm high, with 264 parts and 27 jewels, running at 28,800 V.P.H. (4 Hz) for a stated 40-hour power reserve, and it carries a balance-stop function. Turning the watch over, Vacheron Constantin describes an openworked case back showing an elevated oscillating weight in 22K gold, drawing on the Maltese cross for its shape. The watch is certified to the Hallmark of Geneva; Vacheron Constantin dates the mark to 1886, when the Republic and Canton of Geneva introduced it as a mark of quality and reliable workmanship.
For collectors
This reference shows day, date and power reserve by hand on the dial rather than through apertures.
