Above and below, the Breguet Souscription No. 3424 - circa 1797
The latest addition to the line is the new Tradition Quantième Rétrograde 7597 whose opeworked dial displays not only the hours and minutes but also a retrograde date, a complication that was first developed by Abraham-Louis Breguet.
Housed in a 40 mm white gold case with fluted caseband, the 505Q self-winding caliber is equipped with a reverse in-line lever escapement with silicon horns, as well as a Breguet balance spring also in silicon for increased accuracy and stability. Beating at the frequency of 3 Hz (21,600 vibrations per hour), it offers a power reserve of 50 hours.
The transparent caseback displays the a gold rotor whose unusual shape is reminiscent of that of the first self-winding watches created by the master watchmaker and known as Perpetuelles.
The symmetrical design of the dial is characterized by the hour and minute dial at 12 o'clock, the large central barrel, and the center wheel at 8 o’clock triggering the oscillating mechanism of the same size at 4 o’clock. This is equipped with the famous pare-chute, another invention of Breguet, that is considered the ancestor of the anti-shock mechanisms.
Made of gold, the hour and minute dial features an hours chapter with Roman numerals, bordered by a delicate engine-turned Clous de Paris pattern, which serves as a backdrop for the signature blued Breguet hands.
The retrograde date section is beautifully positioned between the 3 o’clock and 9 o’clock with a curved hand to indicate the date moving in the vertical plane.
A detail that will delight many watch enthusiasts, the date hand is multi-tiered, allowing it to fly over the movement components. At 10 o’clock, the screw-in corrector at 10 o'clock can be used to set the date.
