No-nonsense, overbuilt, and ready for anything. The Sinn U1 is as tough as they come. Its 44mm case is forged from actual German submarine steel, making it ridiculously strong and corrosion-resistant. With 1,000m water resistance and a TEGIMENT-coated bezel that laughs at scratches, it’s built for real-world abuse. The matte black dial keeps things clean and legible, proving that sometimes, less is more, especially when it’s engineered this well.
