2021 Sinn U50 Fully Tegimented Automatic 40mm 1050.030
Ref: 1050.030

Here we have a 2021 Sinn U50 Fully Tegimented Automatic 1050.030 with a 41mm bead blasted German submarine stainless steel case treated with a hard coating to be scratch resistant and sea water resistant. TEGIMENT Technology enhances the hardness of base materials, such as stainless steel, offering excellent protection against scratches. This innovative process hardens the material's surface, creating a durable protective layer called “tegimentum,” derived from Latin. The thick curved, drilled lugs have a lug-to-lug length of 47mm and a thickness of 11mm, giving the watch an impressive wrist presence. On the right side at 4 o’clock, a TEGIMENT Technology-treated signed screw-down crown. The unidirectional bezel has deep scalloped knurling for extra grip. A 60-minute scale highlighted in red from 15-60 with an inverted triangle at 12 o’clock. The flat sapphire crystal AR coated on both sides sits above a black dial. An outer minute track has blocks of SuperLuminova marking the hours. At 3 o’clock, a colour-matched date window. The flat red baton hands have lume tips complemented by a red centre second hand with a lume tip and a red counterweight. The text is minimalist, with “Sinn” at 12 o’clock and “U50 Automatik” and “500M 50 BAR” in red print. The dial's simplicity makes for a very legible dive watch. On the reverse, a screw-down case back. Inside an Automatic Sellita Cal. SW300-1, 25 jewels, beating at 28,800 beats per hour, it has hacking seconds for your convenience. It comes paired with its original Sinn 20mm fitted and cut rubber strap with a signed folding clasp, TEGIMENT Technology treated, it will fit up to a 6.75-inch wrist, and new straps can be had from Sinn. This watch is sold with its original Sinn presentation box, spring bar removal tool and Sinn paperwork.
