Quick TakeThe Sinn U2 S EZM 5 isn't just a watch; it's a statement of resilience and professional-grade engineering. It whispers of deep dives and extreme conditions, not in a boastful shout, but in the quiet confidence of German Submarine Steel. Feel that substantial 114-gram weight (without the strap, of course) on your wrist. You are linked to an instrument designed to thrive where most wouldn't dare to venture. From the Ar-Dehumidifying Technology ensuring a crystal-clear view to the DNV certification guaranteeing water resistance to a staggering 2,000 meters, this is pure, unadulterated functionality. The 24-hour second time zone hand acts like a subtle nod to global explorers, while that matte black dial with its intensely luminous markings is all about pure, at-a-glance clarity. Forget delicate; this Sinn is a beast, beautifully refined, purpose build and ready for anything you throw at it!

DescriptionThe Sinn U2 S EZM 5, reference 1020.020, represents a robust, purpose-built instrument designed for professional diving applications. Its construction centers around the utilization of high-strength, seawater-resistant German Submarine Steel, ensuring exceptional durability and anti-magnetic properties, as defined by DIN 8309 standards. This steel forms the foundation of the 44mm diameter case, which exhibits a thickness of 15.5mm and a lug width accommodating a 22mm strap. The included bracelet is also made of bead-blasted stainless steel with a black hard coating, matching the watch's resilient character. The case back is securely screw-fastened, contributing to the significant water resistance. The watch features a second time zone function, displayed on a 24-hour basis, providing added utility for the user, and the date display adds everyday practicality.

The U2 S EZM 5 is certified by DNV to a diving depth of 2,000 meters (200 bar), adhering to the technical requirements outlined in DIN 8310 for water resistance, as well as the diving-specific DIN 8306. Further, the watch is tested according to European diving equipment standards EN 250 and EN14143, further confirming its professional-grade credentials. Sinn incorporates their proprietary Ar-Dehumidifying Technology. This, through protective gas filling and EDR (Extreme Diffusion-Reducing) seals in the case, is used to prevent the fogging issues and ensures the watch's internal environment remains dry. The seals showcase exceptional chemical resistance and reduced gas permeability, only a quarter that of standard seals. The use of a slightly domed 4.2mm thick sapphire crystal, coated on both sides with anti-reflective treatment, ensures optimal legibility and resistance to extreme pressures. The movement within is the SW 330-1, a self-winding caliber featuring 25 bearing jewels. It oscillates at a frequency of 28,800 semi-oscillations per hour and features a stop-seconds mechanism for precise time setting. Functionality extends across a wide temperature range, guaranteed from -45°C to +80°C, thanks to Sinn's Temperature Resistance Technology and adjustment of component tolerances. The captive diver's bezel, coated with Black Hard Coating on a TEGIMENT Technology basis, offers minute ratcheting for secure time measurement, the Sinn states. A screwable crown, is positioned at 4 o'clock. The dial is matte black with indices and hands (hour, minute, and second) generously coated with luminescent material.
