U-Boat U-65 – Watching the time through a porthole

The U-65, a 44 mm automatic watch in SS Turquoise by U-Boat Italo Fontana, presents a fresh take on timekeeping: more rounded, more fluid

by Sophia Negri

The Italo Fontana U-Boat, the U-65 Turchese, doesn’t just tell the time – it redefines it, inspiring the wearer to think “out of the box”.

    The hyper-curved timepiece embodies the fusion of contemporary design and precision mechanics. The domed crystal showcases the exposed skeletonised movement, allowing the mechanism to be admired in real time: a true spectacle of mechanical perfection. A striking timepiece that showcases its intricate inner mechanics, embodying personality and innovation. The Miyota 8N24 Skeleton mechanical movement is self-winding and boasts a 42-hour power reserve.

The strap is made of silicone. The lugs connecting the strap feature a special adjustable mechanism, designed to fit the wrist perfectly.

     Demonstrating Swiss mastery, the Ronda 756 quartz movement is oil-lubricated. The case is made of 316L stainless steel. The case back is crafted from stainless steel with a turquoise mineral crystal, secured with six screws. The black metal dial features applied metal hour markers and numerals with turquoise Superluminova coating. The K9 mineral crystal is domed. The U-65 is water-resistant to a depth of 50 metres and can withstand a pressure of 5 atmospheres.

The case is crafted from AISI 316L stainless steel and is fully filled with a special oil that enhances the dial, creating the illusion of no glass and resulting in more vivid colours and better readability. A visible air bubble on the dial balances temperature changes.
