Men's Tegiment Blue Silicone Strap Watch U1 B

The stainless steel dive watch for the German submarine, with a blue dial.

The Watch
Sinn unveils a true diver's watch that will captivate passionate sea and ocean explorers. Water-resistant to 1,000 meters, it becomes your ultimate companion for the deepest underwater excursions. It features a silver-tone stainless steel case with a captive rotating bezel - and unmistakably masculine proportions: 44 mm in diameter, 14.7 mm thick, and 113 g in weight (strap excluded). The case is also treated with Tegiment technology for exceptional scratch resistance. The dive-specific bezel features a countdown timer and a luminescent marker. A sapphire crystal protects the entire watch jewelry piece against unsightly scratches, with anti-reflective coating on both sides for superior dial legibility. A screwed crown at 4 o'clock lets you wind the movement, while the screwed case back conceals this timepiece's automatic movement.

The Dial
Dressed in a magnificent galvanized blue, the round dial of this U1 B brings together design, functionality, and performance. Its clean layout delivers outstanding legibility. Three central hands sweep to mark the hours, minutes, and seconds. White rectangular hour markers around the dial create a bold contrast against the blue background for excellent readability, surrounded by a minute railway track for added precision. A square date window sits at 3 o'clock, displaying white characters on a black background. The indices and hour, minute, and second hands are coated with luminescent material - keeping time readable through all your nighttime adventures. Finally, the brand signs this piece at 12 o'clock, and on the opposite side indicates the movement type, water resistance rating, and place of manufacture.

The Movement
An automatic movement powers this entire timepiece. Swiss-made by Sellita, the SW 200-1 caliber drives the central hour, minute, and second hands, as well as the date window at 3 o'clock. Built with 26 jewels, it runs at 28,800 vph, delivers a 38-hour power reserve, and features a hacking seconds function. Shock-resistant, this movement also offers protection against magnetic fields in compliance with DIN 8309.

The Strap
This dive watch comes paired with a blue silicone strap. Designed for maximum comfort, it will accompany you on every dive. The lug width measures 22 mm, and the strap fastens with a large single deployment clasp.

Water Resistance
With a water resistance of 1,000 meters - or 100 ATM in watchmaking terms - Captain Nemo himself would envy this timepiece built for the deep. Showers, baths, swimming, freediving, or scuba diving: this watch takes it all in stride and comes out gleaming! Our Ocarat watch experts ask just two things of you:
Do not operate the pushers or crown while submerged.
