The first world-time watch serving to adjust the second time zone to the nearest minute, the Duomètre Unique Travel Time in pink gold reveals the various facets of horological excellence and the over 180 year-old heritage of expertise forged by the prestigious Manufacture in Le Sentier. Travellers no longer have to make do with merely approximate local-time indications when the continent or country being visited shows a time difference in fractions of hours – as is the case in certain regions. No less than 498 parts are required to make the Jaeger-LeCoultre Calibre 383 equipped with the famous Dual Wing system. The latter comprises two mechanisms sharing the same regulating organ : one to display local time and the other that of a second time zone (which does not influence the operation of the former). Each endowed with a 50-hour power reserve (indicated beneath each of the counters), the two barrels are wound by the same crown – clockwise for the time zone and counter-clockwise for the time. The crown serves to adjust travel time when it is in position 1, and home time in position 2. Once the two time zones have been synchronised, the wearer presses the push-pieces at 8 and 10 o’clock to adjust the jumping hour in the left-hand counter according to the destination country. The aesthetically harmonious dial provides its display trilogy in a delightfully rounded manner, with local hours and minutes at 2 o’clock, the world map at 6 o’clock, and travel jumping hours and minutes at 10 o’clock. The globe adjusted to the travel time zone features a world map punctuated with indications of the various time zones and surrounded by a subtle day/night display. The simplicity of the read-off on the finely grained dial surface is inversely proportional to the complexity of the movement beneath. In keeping with the brand’s grand tradition of pocket watches, the bridges and wheel trains of the Duomètre feature polished sinks and are hand-bevelled, while the moving parts are snailed or smoothed. These Fine Watchmaking finishes are revealed through the sapphire back of the white gold case, rimmed with the engraved names of the cities corresponding to the 24 time zones. Horological passion transcends all known borders…
