Vacheron Constantin has added a new variation on its Overseas Dual Time watch, which debuted in gold and steel with silver and blue dial options in 2018. The new men’s model is distinguished by an enticing black lacquered dial and features all the elements Vacheron introduced into the Overseas collection when it redesigned it in 2016: a six-sided bezel inspired by Vacheron’s Maltese cross emblem; an in-house-made, mechanical self-winding movement with a 22k gold rotor embellished with a wind rose; and a patented easy-adjust/easy-replace strap and bracelet system.
The 41-mm steel case of the new Overseas Dual Time is water-resistant to 150 meters thanks in part to a screwed-down crown and is fitted in its interior with a soft iron inner casing ring whose job is to protect the movement from the harmful effects of magnetic fields. The translucent, black lacquered dial has a sunburst satin-finished base and a velvet-finished flange. The faceted hands and hour indices are made of 18k white gold and treated with white Super-LumiNova.
Driving the watch’s functions is the manufacture Caliber 5110 DT, derived from the base 5110 movement. The fruits of several years of development, its signature function is the simultaneous reading of two time zones on co-axial hands. The main hour hand indicates the wearer’s local time in his current location, while the red-triangular-arrow-tipped GMT hand points to the home time or “reference time” on the 12-hour scale, which is linked to the day-night (“AM/PM”) indicator at 9 o’clock, allowing a traveler wearing the watch to determine at a glance if it’s daytime or nighttime back home. The crown’s first position adjusts the local time in independent, jumping hour increments; the second position sets the home time with dragging adjustments of both time zone hours and minutes. In the 6 o’clock subdial, a pointer-type date indication, synchronized with the local time, is adjusted via the screw-locked pusher at 4 o’clock.
On display behind a sapphire caseback window, the self-winding movement is made up of 234 components and stores a lengthy 60-hour power reserve in its twin mainspring barrels while oscillating at a frequency of 28,800 vph (4 Hz). In addition to the elegantly adorned gold rotor with the engraved wind rose, a symbol of early maritime navigation, the movement boasts all the haute horlogerie decorations necessary to earn the prestigious Hallmark of Geneva. This all-black version of the Overseas Dual Time is delivered on a stainless steel bracelet with half-Maltese-cross-shaped polished and satin-brushed links, along with two additional, easily changeable straps, one in black Mississippi alligator leather, the other in black rubber. The watch will arrive in stores in December 2019 and will be priced at $22,900.
