The U-BOAT Capsoil collection combines unique design with retro style and highly durable materials. The mechanism of the U-BOAT CAPSOIL SS 8110/A watch is fully immersed in low viscosity oil, giving the dial a sense of depth and brightening the dial for improved legibility. The impression of depth is completed by an air bubble on the dial, which moves on the dial as the wrist moves, giving the impression that the entire watch is under water. In the depths, the strikingly large beige superluminova indexes and hands shine against the black background, and the glass is scratch-resistant convex sapphire glass. The 45 mm wide steel case of the U-BOAT CAPSOIL SS 8110/A wristwatch is made of ASTM International AISI-standardised surgical steel, and the surface is DLC-treated, giving the case a high-strength finish. The strap is made of vulcanised rubber. The operating temperature range of the watch is 0-60 degrees Celsius.
The Italian U-boat watches are handmade in Lucca, Tuscany, Italy from premium materials and feature Swiss machinery. U-boat watches come with a 2-year warranty and are delivered in the manufacturer's original watch case.
