Behind every U-Boat watch lies a true spirit of craftsmanship and a distinct aesthetic vision. Blending cutting-edge technology with precision, every piece is handcrafted in Italy by the brand's finest master watchmakers. Every detail of this 9503 from the Darkmoon Collection has been meticulously refined to sit perfectly on the wearer's wrist. It features a 316L stainless steel case with a black PVD treatment. At 40 mm in diameter, its round case is completely filled with a special oil that draws the eye to the center, creating the illusion of a crystal-free dial and an optical effect that enhances legibility. You'll also notice an air bubble on the dial that compensates for temperature changes. A high-quality domed sapphire crystal covers the surface, protecting it against everyday scratches and scuffs. A screw-down crown at 3 o'clock handles time-setting. Thanks to the screw-down case back, the watch is water-resistant to 50 bars - and it features an innovative locking system with a quick-change battery replacement.
This piece features a round dial full of character and charm. Its captivating green tone is elevated by a stunning sunray finish with a smoky depth that makes every line on your wrist catch the light. The dial is beautifully dressed with beige time markers - their warm tone the result of a Luminova treatment, ensuring legibility in any lighting condition. When the two baton hands align with the indices, you can read the hours and minutes with absolute confidence. The hour markers around the perimeter are a mix of batons, two Arabic numerals, and the brand's iconic U logo. Above the 6 o'clock index, the dial carries the collection name alongside key watch specifications. At 12 o'clock, the brand places its signature as a mark of authenticity.
This round case houses the Ronda 762 quartz caliber. Of Swiss manufacture, this oil-bath lubricated movement keeps the hands running smoothly, delivering reliable and precise analog timekeeping.
An elegant strap in ultra-durable black vulcanized rubber completes the watch. It wraps around the wrist with a refined feel and exceptional comfort. The lug width measures 20 mm, and its black color pairs effortlessly with any look. The strap is secured by a pin buckle in 18 mm black PVD stainless steel.
This model delivers water resistance up to 50 atmospheres, or 500 meters - more than enough to dive 20,000 leagues under the sea with the kids in the pool, or tackle the serious stuff like professional scuba diving. The deep awaits, and you're ready for it. The Ocarat team wishes you happy exploring - just remember: don't operate the pushers or crown on the way down!
