HD10 "Porte Noire" Watch

The Watch

The creations of Humbert-Droz are synonymous with perfection, precision, and quality. Modern and refined, they showcase a bold, avant-garde design that reflects four generations of manufacture expertise and ingenuity. Today, we are proud to unveil this stunning HD10 "Porte Noire" model - a blend of retro-modern understatement and cutting-edge watchmaking that pays tribute to the Gallo-Roman triumphal arch erected under Emperor Marcus Aurelius. Built in the 2nd century at the starting point of the main road connecting Rome to Vesontio (Besançon), it was originally adorned with intricate sculptures of heroes and deities from Greek and Roman mythology. This exceptional model features a cushion-shaped case in 316L stainless steel measuring 44 mm in diameter (crown included) with a thickness of 13.50 mm. Its brushed finish and commanding case give it a sophisticated edge. The black PVD treatment is complemented by four visible screws for a more dynamic look. The dial is protected by a domed sapphire crystal that guards against shocks and daily wear. A black carbon screw-down protected crown at 3 o'clock handles adjustment of the central indicators. Finally, the screw-down transparent caseback showcases the movement while ensuring 10 ATM water resistance.

The Dial

This beautiful watch features a round black dial that adds a touch of sophistication to your wrist on any occasion. A true expression of elegance and restraint, it accentuates the timepiece's modern appeal. Stripped of any superfluous detail, it delivers the time with quiet authority. The indices blend into the tone, rendered as bold Arabic numerals and baton markers in relief. They frame two satin-black hands coated in Luminova for the hours and minutes. These are joined by a seconds hand with an arrow tip. The outer edge features a minute track punctuated at intervals by 10 white Arabic numerals. The open heart at 6 o'clock adds originality and offers a glimpse of the mechanism. The brand signs its name just below the 12 o'clock index.

The Movement

This magnificent timepiece is powered by a Franco-Swiss automatic movement renowned for its reliability and precision - specifically the La Joux-Perret G1A0 caliber, which ensures accurate display of hours, minutes, and seconds. Its power reserve reaches 68 hours.

The Strap

The strap that accompanies this beautiful watch amplifies its elegance and unique style. Crafted from black carbon-embossed bovine leather, it strikes a sporty yet refined balance that elevates any look. Tone-on-tone topstitching adds to its charm, and it will fit your wrist perfectly for all-day comfort. It fastens effortlessly with a stainless steel deployment clasp.

Water Resistance

With 100-meter water resistance, or 10 ATM, this bold timepiece is as comfortable at a gala as it is in the water. Wear it in the shower, the bath, or while swimming - even during energetic laps. That said, our team of watch experts is clear: this model is not designed for scuba diving, freediving, or high-pressure water jets. Remember: shower, bath, and swimming only - and keep the pushers and crown dry.
