Featuring the World's First Magnetic Pivot

A Cutting-Edge Watch Ticking at Ultra-High Beat

The new "Classique Chronométrie 7727" is a groundbreaking model that not only uses magnetic pivots to freely control "magnetism," which can adversely affect watches, but also utilizes it to improve the pivot position, rotation, and stability of the balance staff.Breguet's new revolutionary watch has arrived.

A Spirit of Pursuing Innovation

BreguetBaselworld 2013The new "Classique Chronométrie 7727," announced at Baselworld 2013, is an ultra-high precision model featuring a silicon double balance spring and an inline Swiss lever escapement ticking at an ultra-high beat of 20 vibrations per second (10Hz), or 72,000 vibrations per hour. Additionally, it is equipped with a "magnetic pivot mechanism" for the escapement's balance staff bearing, which stabilizes its position and enables higher precision operation.

Remarkably, the average daily rate is within -1 to +3 seconds, and the positional variation over 24 hours in six positions is within -2 to +4 seconds. This far surpasses the -4 to +6 seconds daily rate of a COSC-certified chronometer.

At the upper left of the small seconds subdial at 12 o'clock, there is a small subdial and hand that completes a rotation every two seconds. This rapidly rotating element serves to highlight the watch's ultra-high beat capability.
