http://www.thewatchbox.com The Jaeger-LeCoultre Master Geographic represents the fusion of JLC's 42-day Master Control timing test and its signature "Geographic" complication. While the Jaeger-LeCoultre Geographic line launched in 1990, it didn't become subject to the revolutionary "Master Control" testing regimen until the 1996 debut of the 37.5mm model you see here. JLC developed the Master Control test to evaluate and validate the timing stability and proper function of its watches as fully-cased and regulated products. Unlike the COSC chronometer test, which evaluates only uncased movements, and only in limited circumstances for 15 days, the Master Control tests cased watches through innumerable positions, temperatures, shocks, magnetism, dynamic winding, water exposure, and full power reserve. Jaeger-LeCoultre's Geographic function operates like a selective world time complication. A user-configurable reference ring features the names of 24 cities corresponding to the 24 primary time zones. By synchronizing both time displays to local time with the current reference city at the index, the system is primed. Simply rotate the reference ring to place a reference city at the index, and the current time in that city can be read. There's even an AM/PM indicator to avoid accidental 4AM phone follies. This Jaeger-LeCoultre Master Geographic is available from thewatchbox.com with full factory paperwork, manuals, boxes, and accessories. Video and content by Tim Mosso.
