We have a number of Breguet watches, including this Breguet Classique Chronometrie 7727.
The new Breguet Classique Chronometrie 7727 is equipped with a special high frequency escapement, beating at 10 hertz. The Classique Chronometrie is expected by Breguet, once production begins (expect the watch to start to appear in limited numbers in Breguet boutiques this fall) to show a maximum daily variation in rate of one second or less.
High speed escapements need extremely light components –like F1 cars, weight is the enemy, and as in an F1 car high tech materials are needed. The escapement components of the Classique 7727 are made of ultra light silicon, etched from paper thin wafers using technology borrowed from the semiconductor industry. Since silicon is glass-smooth, no oil’s needed in the escapement either –contributing to both the longevity and accuracy of the watch.
The Classique has another trick up its sleeve: magnetism. In an ordinary wristwatch, the balance wheel’s pivots sit in ruby bearings, lubricated by a tiny drop of oil. In the Classique 7727, the bottom pivot of the balance is held in place by a powerful permanent magnet –a technology unique to Breguet, and one which helps ensure that the watch will run at the same rate regardless of the position it’s in, unlike a normal watch, which runs at a slightly different rate in different positions. Magnets are normally anathema in watchmaking –exposure to a strong magnetic field makes most watches either run wildly inaccurately or even stop completely –but the Classique 7727 is immune to the effects of magnetic fields thanks to the amagnetic nature of silicon.
Despite its triple threat technology (fast beat escapement, silicon escapement and balance spring, and magnetic bearings) it’s housed in formalwear that the company’s founder, Abraham Louis Breguet, would have recognized immediately had he seen the watch in his heyday in the early 19th century. The coin-edge case fluting, pomme style hands, and immaculately executed guilloché finish are all classic Breguet design elements (the prototype shown has “10 Hz” in red on the dial, but CEO Marc Hayek assured us when we saw the watch at the BaselWorld watch show that that element would be removed in the final production watch.) No news yet on pricing but we expect Breguet collectors to compete fiercely for bragging rights to own the most technologically advanced watch Breguet has ever made.
