Master Control 1000 Hours - A pioneer in watchmaking, Jaeger-Le Coultre set new benchmarks in reliability. Upon completion, every single one of their watches must pass the severe master control test programme, where the watches undergo the most demanding testing for a 1000 hours. The master control test is superior to the official chronometer test, which only tests the movement. Jaeger-Le Coultre tests the finished watch in its case and with hands.
