Jaeger LeCoultre Grande Complication a Triptyque: Details

The watch, in White Gold. Limited to an edition of 20 pieces, this is No 1.

Slide open a lock at the crown side, and the case slides out, like any other Reversos, but as the Triptyque opens, it reveals the other dial with the celestial indications and the perpetual calendar:

The movement is completely contained in the sliding case, so once a day, it transmits a signal via the pin located at the top of the case, to set the indicators of the perpetual calendar. The documentation indicates this occurs instantaneously, but there is no way to observe this as it occurs when the case is closed. A small indicator in red on the front main dial shows the hours where this pin is active, and with an interlock system, prevents the case from being slid open. Clever.

The watch wears rather well, though thick as it needs to contain the mechanism for the complications:
