Overview
A second time zone with day/night and date, across two metals
The Vacheron Constantin Overseas Dual Time, reference 7920V/210R-B965, in 18K pink gold with an intense green-lacquered dial, on the pink gold 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.
The reference 7920V is Vacheron Constantin's Overseas Dual Time, built on the self-winding calibre 5110 DT/2 in 18K pink gold or stainless steel, 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. Every execution 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. Each execution's 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, as set out in that record's own Additional Accessories row.
For collectors
All four executions share this case, calibre 5110 DT/2 and Hallmark of Geneva certification; what changes is the case metal, the dial colour and, on one execution, which strap is fitted as the primary wear rather than the metal bracelet -- worth checking a specific record's own bracelet and clasp rows before assuming which is fitted.
