Quick TakeThe Sinn U2 is more than just a diving watch; it's a statement. Crafted from bead-blasted German Submarine Steel, it exudes a rugged capability, a tool built for serious underwater exploration. The TEGIMENT Technology turns the entire case into a scratch-resistant fortress, and its captive bezel clicks with crisp precision with each measured minute. Peer through the anti-reflective sapphire crystal, and you'll find a stark, legible dial. Feel the smooth sweep of the SW330-1 movement, a testament to German engineering. With 2000 meters of water resistance and the innovative Ar-Dehumidifying Technology, this watch doesn't just tell time, it tells a story of exploration, resilience and adventure, whether deep below the surface or pushing limits on dry land. The addition of a 24 hour second time zone speaks to functionality, and the Temperature Resistance Techology allows this piece to maintain reliablility on any expedition, be it hot or sub zero.

DescriptionThe Sinn reference 1020.030, designated as the U2 (EZM 5), represents a purpose-built mission timer engineered for professional diving applications. Its construction centers around the utilization of high-strength, seawater-resistant German Submarine Steel. This material is bead-blasted, providing a matte finish, while also bestowing significant anti-magnetic qualities, compliant with DIN 8309 standards. The watch features a case diameter of 44 mm, a band lug width of 22 mm, and a case thickness measuring 15.5 mm. The weight, excluding the strap, is documented at 114 grams. This model incorporates Sinn's TEGIMENT Technology, applied to both the case and bezel. This substantially increases the surface hardness, creating superior resistance to scratches.

The movement employed within the U2 is the SW 330-1, a self-winding caliber featuring 25 bearing jewels. It operates at a frequency of 28,800 semi-oscillations per hour and provides a seconds stop function for precise time-setting. Core functionality includes the display of hours, minutes, and seconds. The dial presents a secondary time zone, tracked on a 24-hour scale, and a date display. Readability is enhanced via a matte black dial with indices and hands (hour, minute, and second) treated with luminescent material. Sinn's Ar-Dehumidifying Technology, including EDR seals, is integrated to mitigate internal fogging. Three drying capsules maintain a dry internal environment, and a protective gas fills the case. The slightly domed sapphire crystal, measuring 4.2mm in thickness, features anti-reflective coating on both sides. Functional reliability is ensured across a temperature spectrum of –45 °C to +80 °C, thanks to Sinn's proprietary Temperature Resistance Technology and specially adjusted tolerances. The U2 has undergone rigorous testing and has obtained certification from DNV, confirming its water and pressure resistance to a diving depth of 2,000 meters (equivalent to 200 bar). This testing is based on European diving equipment standards EN 250 and EN14143, as well as the diving norm DIN 8306. Additional specifications include a captive diver's bezel with minute ratcheting and a screw-down crown positioned at 4 o'clock. The watch comes with black silicone strap, and clasp.
