Master Ultra Thin Date

In Context

At 40 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. The 7.5 mm case is genuinely slim and goes under a shirt cuff without argument. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse. 50 m covers rain and hand-washing comfortably; it is not a watch to swim in.

The movement winds itself from the motion of your wrist. 43 hours of reserve carries it overnight, but not through a weekend in a drawer. At 28,800 vph the seconds hand advances 8 times a second.

1288420 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver sunburst dial with a stainless steel case. Introduced in 2015.

The mechanical automatic movement, Jaeger-LeCoultre Calibre 899, offers a 43-hour power reserve. Following in the grand tradition of the Manufacture, Jaeger-LeCoultre Calibre 899 is decorated and assembled by hand.
