Introduction: Crafting Unique Timepieces

NEW U-Boat Darkmoon ‘Unico’

In the realm of watches, U-Boat has consistently set itself apart with designs that blend robust functionality with a striking visual aesthetic. To be honest, they have normally been a little too over the top for me and slightly cartoonish.  The latest addition to their lineup, the U-Boat Darkmoon “Unico, is a refreshing change without comprising their integrity.

Artisanal Design: Oxidized Bronze PVD Steel Case


The U-Boat Darkmoon “Unico” is encased in a bronze PVD steel frame that has undergone a meticulous manual treatment involving multiple acids. This process not only oxidizes the surface but also gives it an antiqued look that extends to the dial, offering each piece a distinct character and making every watch truly one-of-a-kind.

Oil Immersion Concept: Enhanced Visual Depth


A standout feature of the Darkmoon “Unico” besides the crown being on the left side of the case  is its implementation of the Oil Immersion concept. The entire case is filled with a special oil that not only protects the internal components but also enhances the visual depth of the dial. This creates an illusion of the absence of glass, which intensifies the color effects and improves readability under different lighting conditions. The presence of a compensating bubble and a domed dial with black numbers and indices amplify this three-dimensional effect, showcasing the watch’s intricate details and the unique imperfections from the oxidation process. In my opinion, while the concept is intriguing, the presence of the bubble disrupts the dial’s symmetry and compromises the clarity of its display.


Technical Specifications: Precision Meets Durability
  • Case Dimensions: 44.8mm diameter, made from stainless steel with aged bronze PVD treatment.
  • Crystal: Curved AR-coated sapphire crystal.
  • Crown and Caseback: Distinctive left-sided crown protector with an innovative Locking Ring System for easy battery replacement.
  • Water Resistance: Up to 50 meters.
  • Movement: Swiss quartz Ronda caliber 712.3, lubricated in an oil bath.
  • Functions: Displays hours and minutes.

Visual Elements: Superluminova and Domed Dial

The domed dial of the Darkmoon “Unico” features painted metal with an aged finish, complemented by indices and numbers treated with black Superluminova for enhanced visibility. The hands are also coated with black Superluminova. A visible air bubble is ingeniously included on the dial to compensate for temperature variations, adding both functionality and a unique aesthetic touch.

Luxurious Strap: Tuscan Cognac Leather

Accompanying this exquisite timepiece is a 22mm Tuscan cognac laser-cut leather strap, aged naturally and stitched with waxed cotton. The steel pin buckle, treated with aged bronze PVD, echoes the watch’s vintage appeal while ensuring durability and comfort.

At the end of the day…

The U-Boat Darkmoon “Unico” is more than just a timepiece; it’s a work of art that embodies the fusion of artistic craftsmanship and modern watchmaking technology.At the end of the day, each watch’s unique imperfections and sophisticated design make it unique for collectors and fashion aficionados alike, seeking a watch that stands out for its historical charm and cutting-edge features.

Due to the unpredictable and volatile market on certain Rolex, Patek Philippe and Audemars Piguet watches, prices are subject to change.
