Vacheron Constantin Introduces the Overseas Dual Time with a Black Dial

That's two-tone.

Launched last year in steel with a blue or silver dial (and also in 18k rose gold), the Vacheron Constantin Overseas Dual Time is now available in the most obvious dial colour – black.

Though not readily discernible in photos, the new black dial is made up of glossy, translucent black lacquer over a sunburst-brushed surface, giving it a slightly nuanced colour that’s similar to that found on the Overseas Perpetual Calendar with a blue lacquer dial. And because the minute track is printed on a matte, granular chapter ring, the result is a subtle, two-tone dial.

Dial aside the watch is identical to the earlier Overseas Dual Time. Home time is indicated by a red-tipped hour hand in the centre, which is in turn linked to the day and night display at nine o’clock.

The second time zone is set via the crown, but the quickset corrector for the date function is operated via a screw-down pusher at four o’clock.

It’s powered by the 5110 DT, a variation of the brand’s workhorse automatic movement that is widely used throughout the Overseas line. As with all Overseas watches, the 5110 DT has a solid gold rotor cast in the form of a compass rose.

The under-dial view of the movement, showing the levers and springs that control the day and night display (at 10 o’clock), and the date (at four o’clock)

And the case includes the quick-release strap mechanism that’s standard across the Overseas range. A small tab easily releases the bracelet or strap, allowing for a rapid swap with the additional strap options delivered with the watch.
