More about Breguet Classique Chronometrie 7727 Manual Wind 18K White Gold 10HZ

This is an 18k white gold Breguet Classique Chronometrie 7727bb/12/9wu. It has an alligator leather strap with an 18k white gold Breguet deployant buckle, and a scratch resistant sapphire crystal. It has a screw down winding crown, and a screw down exhibition sapphire display case back, engraved with a running wave design, and "REF.-BREGUET-2240BC," and several hallmarks. The 41mm diameter solid three-body coin-edged case, straight screwed lugs, and concave bezel, are polished/brushed. The dial is made up of 6 silver guilloche patterns, with the circular center finished with a very fine wave texture. There are two brushed concentric silver reserves, with black Roman numeral hour markers inside a second ring with black dots, and rose gold button indices. It has blued Breguet hands, and a perimeter with a thin ribbon "Barleycorn" guilloche texture. There is a small running seconds indicator with a clous-de-Paris design, and overlapping is a smaller 1/10 of a second sub-dial with a fine starburst guilloche, that makes one rotation every 2 seconds. There is a fan-shaped Power reserve sub-dial at 5 o'clock with a broader wave/step design guilloche pattern, and all the chapter rings are matte silver with black markings. It includes a magnetic pivot bridge at 2 o'clock, with a blued screw and the visible ruby are in the triangular aperture on the dial. It's water resistant to 30 meters/100 feet, and it has a 60-hour power reserve at full wind. The 9,7mm thick case, dial, and movement are all signed. This Breguet Classique Chronometrie 7727bb/12/9wu has a mechanical automatic self-winding Breguet Caliber 574dr movement. It's rhodium plated with Cotes de Geneve stripes on the main bridge, circular graining on the main plate, and polished beveled edges. It's constructed with 35 jewels, and a shock absorber device. Several main parts are made from anti-magnetic silicon, including the pallet lever, balance spring, and balance wheel, which are lightweight and require no lubrication – necessary for a high frequency movement that oscillates at 72,000 VPH (10 Hz). There are magnetic pivot caps on the balance staff to keep it perfectly centered and protected from shock. There are also twin 180° symmetrically mounted balance springs adding to the stability of the oscillator and improving timing precision. The Breguet Classique Chronometrie 7727bb/12/9wu was introduced in 2013, and won the Grand Prix d'Horlogierie de Geneve, or the "Aiguille d'Or" in 2014.
