Overview
A second time zone with day/night and date, across two metals
The Vacheron Constantin Overseas Dual Time, reference 7920V/210A-B334, in stainless steel with a sunburst-finished blue dial and light-blue dual-time hands, on the steel bracelet with its triple folding clasp. Self-winding calibre 5110 DT/2 with a second time zone, day-night and date; 41 mm, 12 mm high, certified to the Hallmark of Geneva.
This execution is the Overseas Dual Time on calibre 5110 DT/2, in stainless steel, with a blue-lacquered dial and light-blue dual-time hands. The bracelet and its triple folding clasp are steel, and the two further straps supplied are dark-blue rubber and dark-blue grained calfskin leather, with a further steel triple folding clasp supplied for use with them.
The reference 7920V is Vacheron Constantin's Overseas Dual Time, built on the self-winding calibre 5110 DT/2, 41 mm across and 12 mm high. The complication combines a second time zone, read against the main hours and minutes, together with a day/night indicator and the date's own aperture; the dial carries a sunburst-finished centre with both a circular internal minute track and a velvet-finished outer one. The watch is water-resistant to 150 m, with a transparent sapphire case back that also carries the antimagnetic marking.
The movement is calibre 5110 DT/2 -- 30.6 mm across, 6 mm high, 234 parts and 37 jewels -- running at 28,800 V.P.H. (4 Hz) for a stated 60-hour power reserve. It is certified to the Hallmark of Geneva; the brand's own account puts the mark's origin in 1886, when Geneva's Republic and Canton adopted it as their own finishing standard, and ties it today to where a piece was made and how well it was built rather than to one technical figure. The primary bracelet or strap interchanges with further options supplied in the box, closed with a spare buckle or clasp in the case's own metal.
