The revamped line of Overseas sports watches unveiled in January at SIHH is now joined by the Overseas World Time that shows the time in all of the world’s 37 time zones. Its all encompassing world time display is thanks to the calibre 2460 WT, the same calibre found in the Traditionelle World Time. The movement can indicate the time in the traditional 24 time zones show by ordinary world time watches, as well as an additional 13 time zones with 15 or 30 minute offsets.

Like the rest of the Overseas range, the movement is fitted with a 22k gold rotor decorated with a relief compass rose. And it’s protected from magnetism by a soft iron ring around the movement that encircles its perimeter but allows the calibre to be seen through the display back. According to Vacheron Constantin, the soft iron ring offered the same degree of protection as a soft iron cage that also covers the back.

All the locations places with unconventional time zone offsets are highlighted in different colour on the dial, though such places are not often visited; they include Tehran, Yangon and Caracas. A tinted sapphire disc in the centre of the dial sits over a metal disc showing the continents in relief – the dark tinted halve of the sapphire indicates night-time in that half of the world.

While Vacheron Constantin’s first world time was available only in gold or platinum, the Overseas World Time is stainless steel, measuring a chunky 43.5mm in diameter and 12.6mm high. The case has the same easily exchangeable bracelet and strap mechanism as the other Overseas watches: a catch on the back of the band releases it from the case, enabling easy swapping between the steel bracelet, rubber and leather straps. All three options are included with the watch.

Three dial colours are available – silver (7700V/110A-B129), blue (ref. 7700V/110A-B172), and brown (ref. 7700V/110A-B176).

Pricing and availability 

The Overseas World Time will reach stores in the third quarter of 2016 and is priced at S$56,900, equivalent to US$41,500.
