All pics - Master Geographic

Tribute to watchmaking tradition, emblematic function of the Manufacture Jaeger Lecoultre, the Master Geographic, in a harmonious dial, displays two time zones incorporating summer time.

 

Each watch in the collection "Master Control 1000 hours" is subjected to a testing program 1000 hours (6 weeks). These tests relate to comprehensive controls around the smooth running, temperature, pressure, impact resistance, sealing and magnetic fields. The watch is well tested in multiple positions that correspond to the most common positions of the watch in his future life. These tests are performed on the movement before mount then, on the watch when she is assembly.
