Jaeger LeCoultre Master Control 25th Anniversary

Jaeger LeCoultre first debuted its Master Control collection in 1992. The idea was “to create a line of watches that represented the values of pure, classic watchmaking, with a focus on simple aesthetics, functionality, understated technology, and long-term performance.” At that time, Jaeger LeCoultre started something impressive – the “1000 Hour Control” quality check program. The purpose was to examine finished watch to a six-week program of tests, which includes impacts, temperature and barometric pressure change, vibrations, magnetic fields, and water resistance. Even though it is standard for watchmaking nowadays, in 1992 such tests were never heard of.


2017 marks the 25th anniversary for Jaeger LeCoultre Master Control Collection, and they present a trio that includes three core complications that have been in the Master Control collection since the beginning: time and date, chronograph, and travel time.


The Master Control Date (Ref. 1548530) is the simplest of the three watches. It has a 39mm stainless steel case with silver dial. The JLC caliber 899/1 features 38-hour power reserve and a solid gold winding rotor.


The Master Control Chronograph (Ref. 1538530) has a versatile design. With 40mm stainless steel case, this watch features chronograph function – 2 sub-dials displaying 30 minutes and 12 hours – on a silver sunray-brushed dial. The in-house JLC calibre 751G offers automatic movement with 65 hours power reserve.


The last watch is the Master Control Geographic (Ref. 1428530). This watch has a 39mm stainless steel case with silver dial. Thanks to the JLC caliber 939B/1, this watch functions a second time zone, which is shown from the sub-dial at 6 o’clock position, and a city disk is right underneath the small dial which shows the names of the city of all 24 time zones.
