Overseas dual time

Vacheron Constantin 2018

ref. 7900V/110A-B334
Men's

Vacheron Constantin extends its Overseas line, updated two years ago, with a function that sits perfectly with the image of travel it conveys, namely a dual-time display with coaxial hands. The hour hand points to local time (the user's current location) while the triangular arrow-tipped hand shows home or reference time. Both times are given over 12 hours and are easily set forwards and backwards by the crown. Completing this dual-time function is a day/night indication, set to home time, and a pointer-type date, synchronised with local time. The movement is the new 5110 DT with 234 components, oscillating at 4 Hz and offering a comfortable 60-hour power reserve thanks to its twin barrel. It is housed inside a 41mm steel case that is water-resistant to 150 metres. As a finishing touch, the bezel suggests the brand's Maltese Cross emblem.
