With a family heritage spanning over 65 years and deep-rooted French craftsmanship, Humbert-Droz creates timeless, elegantly designed watches that blend vintage aesthetics with high-performance features. Ocarat is proud to present this magnificent Platine timepiece from the iconic HD1 collection. The ultimate expression of refinement and sophistication, it projects a distinguished, quietly powerful masculine presence. A limited edition of 300 pieces, it sports a cushion case in 316L stainless steel with a black PVD coating and four visible screws, measuring 43 mm in diameter and 13.50 mm thick - perfectly proportioned to complement any wrist, day or night. A mineral crystal protects the dial, while a carbon black screw-down crown guard on the right side handles manual time-setting. The numbered, screw-down transparent caseback ensures 10 ATM water resistance while treating you to a view of the movement inside.
Humbert-Droz equips its Platine with a round sunray-finished dial. In silver, it features an open heart at 12 o'clock for impeccable time reading while offering a view of the movement. Two black satin hands and a slim black arrow-tipped hand coated in white Luminova display hours, minutes, and seconds in any lighting. The perimeter hosts a minute track with white lines and dots, framed by an Arabic numeral graduation in steps of 10. Hours are marked by Arabic numerals at 3, 6, and 9 o'clock and baton indices elsewhere. The brand signs the watch with its name and movement type at 6 o'clock.
This watch is powered by a Swiss-made automatic movement. Renowned for its exceptional quality and unwavering reliability, the ETA 2824 caliber drives the hands with fluid precision. With 25 jewels and a frequency of 28,800 beats per hour, it delivers a 38-hour power reserve for accurate, dependable timekeeping.
Elegant and modern, a carbon-embossed bovine leather strap enhances the watch's charm with a sophisticated edge. Its black color gives it a refined look, while tone-on-tone stitching delivers that sport-chic appeal. Versatile enough for any occasion, it offers a comfortable fit and pairs with any outfit. With a 24 mm lug width, it features a stainless steel deployment clasp for effortless on and off.
With water resistance to 100 meters - or 10 ATM in the language of watchmaking - this boldly styled timepiece transitions effortlessly from black-tie events to the pool. Wear it in the shower, the bath, or during an energetic swim. Just keep in mind: our watchmaking experts confirm this model is not designed for scuba diving, freediving, or high-pressure water jets. Remember - shower, bath, and swimming only, and never operate the crown or pushers while submerged.
