Hermès Slim d’Hermès L’Heure Impatiente Watch – Innovative Mechanical Hourglass
The Hermès Slim d’Hermès L’Heure Impatiente Watch is one of the most remarkable releases at Baselworld this year. Inspired by the concept of a “Mechanical Hourglass”, it allows the wearer to set the watch to chime at any moment within 12 hours, creating a private and delightful reminder for important events.

Case and Dial Design
This watch features a 40.5mm rose gold case with a silver-white dial, part of the Slim d’Hermès series. The dial design emphasizes clean, original typography and rich textures achieved through grain and snailed decoration. At 4 o’clock, a small dial sets the alarm, indicated by a black arrow for hours and blue steel hands for minutes, adjustable via the crown at 4 o’clock.

Retrograde Countdown and Chime Function
At 7 o’clock, a 60-minute retrograde countdown is controlled by a button at 9 o’clock. When the preset time arrives, a soft and pleasant chime sounds, audible only to the wearer. This unique mechanism allows the passage of time to feel as tangible as flowing sand, merging artistry with functionality.
H1912 Automatic Movement
The watch is powered by Hermès’ in-house H1912 automatic movement, featuring an alarm module developed in collaboration with the Geneva workshop Agenhor. The movement is 3.7mm thick, contains 193 components, beats at 28,800 vph, and offers a 50-hour power reserve. Its design ensures optimal sound quality while keeping the case ultra-thin.

Strap and Wearability
The watch comes with an alligator leather strap, complementing the rose gold case, and is water-resistant up to 30 meters. This combination ensures elegance and comfort, making it suitable for both daily wear and special occasions.
