Bal du temps – Platinum

TECHNICAL SPECIFICATIONS

The high-performance engine that powers this remarkable piece is a hand-wound movement, the calibre L601SQ, made up of 321 parts, produced exclusively in Geneva. It beats at a frequency of 3 Hz (21,600 vibrations per hour) and is equipped with a unique barrel guaranteeing a power reserve of no less than 90 hours. It features a minute repeater mechanism on two gongs, which is activated on demand via the slide at the 9 o'clock position. Once activated, the time indication becomes audible. The hours, quarters and minutes are differentiated by distinct chimes, emitted when the two hammers strike the two gongs.
