The only model revealed ahead of SIHH by Vacheron Constantin is this Overseas traveller model displaying dual time zones.
The watch can be worn three ways with interchangeable steel, leather or rubber straps.
The automatic Vacheron Constantin Caliber 5110 DT with 60-hours of power presents the local time in normal hours and minutes, with a triangular arrow showing a second time zone.
The 41mm watch is sold in three models: two in a stainless steel case with blue or silver dials and a third in 18ct pink gold with a silver dial.
All models have a six-sided bezel inspired by the Maltese Cross that Vacheron uses in its logo.
