Hermès Slim d’Hermès L’heure impatiente Only Watch 2017 Edition

In order to support the prestigious Only Watch 2017charity event, Hermès has created a unique edition of its playful timepiece, the Slim d’Hermès L’heure impatiente.

The Slim d’Hermès L’heure impatiente houses an innovative, playful and quirky ‘Impatient Hour’ complication that enables setting the counter of the watch to the time of the eagerly awaited event that will take place in less than 12 hours. An hour before it occurs, the mechanical hourglass is set in motion and its progress can be followed at 6 o’clock on the dial.

This complication that stirs our feelings and heightens our sense of pleasurable expectation is an exquisite torture that culminates when the note rings out. The striking mechanism has been designed to ensure a lasting, velvety-smooth sound that is also delightfully modulated for the wearer’s ears only.

The L’heure impatiente module, which measures just 2.2 mm thick, is powered by the Manufacture Hermès H1912 movement. This compact calibre housed in a spacious case, the use of thinner than usual crystals, and finally the 1 mm dial that resonates with the vibration of the striking mechanism: everything contributes to optimising the volume of air within this watch distinguished by its blend of aesthetic and technical finesse.
