Vacheron Constantin’s bread and butter may be classically inspired, elegant dress and complicated watches, but their forays into the more avant-garde and into serious tool watches have yielded some of the most interesting timepieces of the past few years.

Launched in 2018, the Overseas Dual Time is a handsome 41mm watch available in steel or in pink gold with multiple strap/bracelet options. Featuring a dual-time complication, AM/PM indicator, a date complication housed in a sub-dial at 6 o’clock, and the in-house cal. 5110 DT with dual barrels and 60 hours of power reserve, this is a serious adventurer’s watch — so much so that American photographer and adventurer Cory Richards wore a special version on Mt. Everest earlier this year (which is going to be auctioned by Phillips this December).

For those who have been waiting with bated breath for a black dial version, the time has finally come. The new reference 7900V/110A-B546 retails for $22,900 (as do the other two steel versions) and features three interchangeable bracelet/strap options — a matching steel bracelet with Maltese Cross-shaped polished and satin-brushed links; an alligator strap featuring a black nubuck lining with hand-stitched scales; and a third rubber strap.

Easily adjustable via the crown and a push-piece, the Overseas Dual Time uses a fourth, red-tipped hand to indicate home time, coupled with a day/night indicator, while the date window at 6 o’clock is synched with local time. The cal. 5110 FT features 234 components and is wound by a 22-carat gold weight, visible through a sapphire case back. Water resistant to 150m and 41mm by 12.8mm thick, it’s one of the clearest expressions of Vacheron Constantin’s desire to push beyond the constrains of 20th-century design.
