There have been blacked-out Sinn U1s in the past, but they've never released the watch with a fully tegimented case with a black coating. That all changes this month as Sinn reveals two new U1s in that highly coveted combo. The entirety of the case (and bracelet) is fully tegimented, a process that increases the watch's scratch and corrosion resistance. It's also shock-resistance, anti-magnetic, and water-resistant down to 1000 meters. That certainly makes for one of the most rugged watches available. The new U1s will come in a few variations with Tegimented bracelets, rubber straps, and your choice of red and white accents or tan accents.
