Sinn EZM 3 S
Model: 603.011
The Sinn EZM 3 S is built for absolute reliability under the most extreme diving conditions. Designed as a mission timer, this watch embodies pure functionality with no compromise. Whether subjected to icy depths, massive pressure, or near-zero visibility, the EZM 3 S delivers clarity, durability, and dependability.
Its striking profile comes from the black hard coating on a TEGIMENT Technology basis, combined with a bead-blasted stainless steel case. This not only gives the watch its bold, technical appearance but also enhances the contrast and legibility of the bezel markings. The crown is placed at 9 o’clock to prevent pressure against the back of the hand, adding a practical ergonomic touch for professional divers.
Certified to European diving equipment standards and tested by an independent institute, the EZM 3 S guarantees water resistance up to 500 metres. It also withstands extreme temperatures from -45°C to +80°C, is protected against magnetic fields up to 100mT, and incorporates Sinn’s Ar-Dehumidifying Technology for long-term reliability and fog-free performance.
Every element of the EZM 3 S reflects Sinn’s commitment to uncompromising engineering. From its matte black mission timer dial for optimal readability, to its proven SW200-1 automatic movement, the EZM 3 S is trusted by professionals who cannot afford failure. This watch is built to perform – 100 percent.
The long awaited EZM 3 S is sure to be an instant hit thanks to its robustness, functionality, and subtle looks. Weather you choose to wear it on a silicone strap or the adjustable PVD bracelet, this mission timer can be relied upon to join you anywhere.
