Classique Chronometrie wristwatch in 18-carat rose gold. High-frequency escapement ( 10Hz ) composed of a magnetic balance with double balance spring, lever and escape wheel in silicon. Hand-wound movement with running seconds. 1/10th of a second sub-dial and power-reserve indicator. Silvered gold dial, hand-engraved on a rose engine. Sapphire case-back. Water-resistant to 3 bar ( 30 m ). Diameter : 41mm. Also in white gold.

Breguet’s Classique Chronometer in 18K Rose gold is a newcomer to this collection of grand complications.

For the 1st time it oscillates at a frequency of 10 Hz. This is the first time that such high frequency has been applied in a non-chronograph watch, since the purpose is to improve the precision and the stability of a conventional mechanical watch. For Breguet, high frequency does not come at the expense of the power reserve. The energy stored in the mainspring barrel of the reference 7727 and its high level of workmanship keep the watch running for 60 hours. The hours and minutes are off-center on the dial, while the small seconds at 12 o’clock recall the first eccentric dial produced by Breguet 200 years ago.

The power-reserve indicator is at 5 o’clock. The dial is beautifully detailed – it displays six engine-turned patterns. The center is in “Geneva waves”, a Clou de Paris hobnailing design adorns the small seconds dial, the tenths-of-a-second counter displays a sunburst pattern, while the power-reserve indicator is decorated in chevrons.  The chapter ring for the hours has an edging decoration and the outside edge is in a barleycorn pattern. This watch is fitted with a caliber 574 DR hand-wound movement with a Breguet magnetic balance oscillating at 10 Hz on a silicon spring, and an in-line Swiss lever escapement in silicon. A stop-seconds feature allows the watch to be set to a time signal. The rose gold case has a sapphire-crystal case-back displaying the movement. Water resistant to 30 meters / 100 feet.
