7047PT/11/9ZU

TRADITION wristwatch in platinum. Hand-wound movement with tourbillon and fusee-chain transmission. The fusee-and-chain transmission connected to the barrel maintains a constant force for as long as the watch is running. A number of patent applications cover the large tourbillon resonator at one o’clock on the watch face, one for a titanium balance and three relating to Breguet silicon balance springs featuring the famed “Breguet overcoil” terminal curve. Producing a curve in a sliver of silicon to give it a third dimension represents a quite considerable watchmaking exploit.

A further patent was awarded for the power-reserve indicator fitted directly on the barrel.

Dial in silvered 18K gold, hand-engraved on a rose engine off-centred at 7 o’clock.

Tourbillon

The tourbillon, A.-L. Breguet's historic invention patented in 1801, was conceived to compensate for rate errors resulting from the effect of gravity on the moving parts.
