DescriptionThe Sinn EZM 3F, reference 703.010, is purpose-built with a focus on functionality and durability. Its core is the SW200-1 self-winding mechanical movement, a robust mechanism featuring 26 bearing jewels and operating at a frequency of 28,800 semi-oscillations per hour. A seconds stop function is included, and the movement meets anti-magnetic standards as defined by DIN 8309. Powering the watch, this mechanical marvel is encased within a bead-blasted stainless steel structure.
The case itself has a diameter of 41mm, providing a substantial presence without being overly bulky. With a band lug width of 20mm and a thickness of 11.7mm, weighting 81 grams without strap. It incorporates several key Sinn technologies: Ar-Dehumidifying Technology mitigates internal fogging, ensuring optimal clarity of the matte black dial. Magnetic Field Protection shields the movement from magnetic interference up to 100mT (80,000 A/m). Furthermore, Temperature Resistance Technology maintains reliable operation between -45°C and +80°C. The EZM 3F's water resistance is rated to 20 bar, meeting DIN 8310 standards, and it is also resistant to low pressure environments. A screw-fastened case back, crafted to be nickel-free, enhances wearer comfort. The design features a bi-directional pilot’s bezel with minute ratcheting, and its design places the screwable crown on the left-hand side, improving usability. The dial, a matte black, maximizes legibility, as the indices, hour, minute, and second hands are coated with luminescent material. The watch is made with sapphire crystal glass, anti-reflective on both sides.
