A watch that tells the time in two different time zones makes a perfect travel companion.
Frequent travellers will appreciate Vacheron Constantin's latest Overseas Dual Time Self-Winding Steel and Titanium timepiece (far right). In addition to the conventional hours, minutes and seconds indication, the timepiece features two subdials (one for the date and another for the second time zone) along with a fan-shaped power-reserve display and day/night indicator. The watch is light because it's made of titanium, which also contributes to its sporty image. Water resistant to 15 bar (150 metres) and priced at HK$127,000, the Overseas Dual Time comes with two straps - one in anthracite grey alligator leather and the other in black rubber.
A highlight of Harry Winston's Opus X (right; HK$1.76 million) is its futuristic design. Inspired by planetary movements, the watch displays local time - hours, minutes and seconds - with three rotating indicators mounted on a revolving 'solar' platform, instead of the conventional fixed dial and hands. The central platform fully rotates over 24 hours. A pointer on the periphery indicates the second time zone. Meanwhile, the dials of each of the three indicators move in an anti-clockwise direction to counterbalance the platform's movement, which means their orientation remains constant whatever the platform's position. The individual satellite wheels, which display the first time zone, 'orbit' around the central wheel, which displays the second time zone. The watch is water resistant to 30 metres and is limited to 100 pieces.
Ulysse Nardin's latest Executive Dual Time (left) has a silver dial - the collection's first - and can be fitted with a choice of rubber (HK$173,100) or leather strap (HK$190,000). The ceramic pushers and matching bezel are set against a stainless-steel or rose-gold case. Using the brand's patented Dual Time system, the second time zone can be adjusted by operating the plus or minus pushers at eight and 10 o'clock, while local time is indicated in a small aperture located at nine o'clock. Water resistant to 100 metres, the 43mm case also houses a small-second counter at six o'clock and a good-sized double window at two o'clock, which displays the date.
