Master Geographic is a perfect traveler’s watch with functions such as multiple time zones, power reserve indication and date counter. This model from Master Control line by Manufacture Jaeger-LeCoultre comes in an elegant 39 millimetre-diameter case.
The Master Geographic is equipped with automatic Jaeger-LeCoultre Calibre 939A. It displays local time by means of large central hour, minute and seconds hands. Meanwhile, the names of the cities representing each of the 24 time zones glide past on the lower part of the dial, in some cases bearing the letter “S” for “Summertime” in order to enable the user to take account of a possible half-yearly change in legal time.
The second time zone selected via a crown appears in a counter at 6 o’clock. The eminently readable dial also provides other information such as the indispensable power reserve and a date counter.
Like all watches from Master Control line, the Master Geographic is exposed to 1000 hours of constant controls. Their rating precision is tested in six positions, at rest and in motion, while the prophylactic administration of calculated shocks proves their sturdiness, and their water resistance is verified under 5-bar pressure.
