Hermès Dressage L’heure Masque

The Dressage L’heure masque is a playful mechanical timepiece in which the hour hand remains hidden beneath the constantly moving minute hand, solely deigning to appear at a deliberate press on a crown-integrated pushbutton. This fleeting apparition captures exclusively the moment in hand and vanishes as soon as the pressure is released – as too does the dual-time window display caught up in the same game of hide and seek.

This playful stage-setting is orchestrated by the ingenious interaction of the rack, pinion and gear trains. When stimulated, the hour cam releases from its hiding place the hand that dutifully appears to perform its role of pointing to the correct hour on the dial.

The dual-time indication is directly driven by the base movement and adjustable via the push button opposite the crown.

In this entirely Manufacture-made composition, self-winding Calibre H1925 is equipped with an exclusive patented mechanism enabling it to play this uniquely personal musical score.
