HERMÈS ARCEAU DUC ATTELÉ MINUTE REPEATER TRIPLE-AXIS TOURBILLON

The influence of this heritage is evident in the intricate details of the movement – for instance, the unusually narrow spokes of the gears, designed to resemble the carriage’s wheels. Additionally, observe the horse-and-mane-shaped quarter rack positioned at 6 o’clock, where the repeater barrel is located alongside the hour rack and rack pinion. At the centre of it all, the minute snail sits adjacent to the 12-toothed star wheel mounted on the hour snail.

The triple-axis tourbillon enhances timekeeping accuracy by mitigating positional errors, while the balance wheel’s 5Hz (36,000 vibrations/hour) frequency enhances its motion stability. However, both mechanisms require considerable energy, and to meet this demand, the timepiece is equipped with a double-barrel system, ensuring a 48-hour power reserve. As one would anticipate, the hand-finishing on the 563-component movement is nothing short of exemplary.
