Quick TakeThe Sinn U2 isn't just a watch; it's an underwater instrument. Forged from German Submarine Steel, this isn't about flashy style, it is about pure, robust function. You’ve got a watch that laughs in the face of extreme depths (2,000 meters!), extreme temperatures (-45°C to +80°C), and even the corrosive wrath of seawater. The matte black dial, with its generously lumed indices and hands, prioritizes at-a-glance readability, no matter how murky the conditions. Sinn’s Ar-Dehumidifying Technology? That's your guarantee against internal fogging, a potential lifeline when you’re deep below the surface. The captive, TEGIMENT-hardened bezel clicks with precision, each minute a solid confirmation of elapsed time. Throw in a 24-hour second time zone function, and you've got a very highly technical, reliable partner, built for extremes. With its bead-blasted finish and bold, functional design, the U2 announces its capabilities boldly.

DescriptionThe Sinn U2, designated as model 1020.010, is purpose-built as a professional diver's instrument. Its core construction utilizes high-strength, seawater-resistant German Submarine Steel, known for exceptional durability and anti-magnetic qualities, satisfying DIN 8309 standards. The 44mm diameter case, with a thickness of 15.5mm and a lug width of 22mm, houses the SW 330-1 self-winding movement. This mechanism features 25 bearing jewels and operates at a frequency of 28,800 semi-oscillations per hour. Added benefits are the inclusion of a seconds stop function, and the watch has a total weight of 114 grams (without the strap). Critical components, such as the slightly domed sapphire crystal glass (4.2mm thick), receive anti-reflective treatment on both sides to enhance visibility under all conditions. The case back is securely screw-fastened, while the crown is screwable, to maintain water resistance.

Key operational features include the display of hours, minutes, and seconds, as well as a date display. A second time zone is indicated on a 24-hour basis. The diver's bezel, crucial for monitoring immersion times, incorporates minute ratcheting, and includes a luminous key mark for low-light legibility. The entire design adheres to Sinn's mission timer philosophy, ensuring maximum readability. Sinn technologies are heavily implemented. The bezel features TEGIMENT Technology, dramatically increasing scratch resistance. A captive design prevents accidental detachment of the bezel. Moreover, Ar-Dehumidifying Technology, which employs EDR seals, a protective gas filling, and three drying capsules, maintains a moisture-free internal environment, improving reliability, eliminating fogging risk and working in conjunction with Temperature Resistance Technology, to allow guaranteed operational capacity at an extreme range; from –45 °C to +80 °C. The model reviewed includes a black integrated silicone strap with a bead blasted stainless steel folding clasp. The U2 is certified by DNV to be water and pressure resistant to a diving depth of 2,000 meters (200 bar) and is compliant with both DIN 8306 and 8310 diving norms, along with European diving equipment standards EN 250 and EN14143. The U2 is also Low pressure resistant.
