Since 2003, Hermès has designed and developed its own mechanical watch calibres, enriching the collection with a fine array of horological complications and fine craftsmanship. Arceau Le Temps Suspendu conceals time and erases it from the dial while continuing to register its ceaseless march. This new horological complication developed exclusively for Hermès is a world's first. The mechanics behind the illusion are created by an additional module, enabling automatic and spontaneous alternation between suspended time and standard time. The 360 degree retrograde hour and minute mechanisms make time disappear without interrupting the relentless running of the movement.
