Sinn "The Mission Timer 7" Watch 857.EZM-7 43mm S.S. ALL Original 2-Box & Papers

Watch Overview We are pleased to present this Sinn EZM 7 “Mission Timer” automatic wristwatch, reference 857.EZM-7, complete with its original inner and outer boxes and papers. Developed specifically for fire brigade and rescue professionals, the EZM 7 is a tool watch designed to perform under extreme conditions, resistant to water, dust, shocks, temperature changes, and magnetic fields. Powered by the self-windig movement caliber SW 330-1, featuring 25 jewels, hacking seconds, a date display, and a second time zone on a 24-hour basis. It beats at 28,800 vibrations per hour. The dial is where this piece truly stands out. It features a black base with large luminous hour markers and bold hands. The signature mission timer layout incorporates color-coded segments and scales that allow the wearer to track different timing phases at a glance. The inner 24-hour scale provides a reference for an additional second time zone. The unidirectional rotating bezel follows the same color-coded system and features a captive design with minute ratcheting. It can be easily operated even while wearing gloves, making it especially practical for professional use. The layout was originally designed to help coordinate breathing apparatus timing (CSA to LPA), but it translates just as well for everyday timing needs. Housed in a 43mm stainless steel case, the watch features Sinn’s Tegiment technology, making it especially resistant to scratches. The case is resistant to magnetic fields up to 100 mT and remains fully functional in extreme temperatures ranging from -45°C to +80°C. The screw-down crown is positioned on the left side of the case, improving comfort on the wrist and protecting it from accidental impact. A sapphire crystal with anti-reflective coating on both sides ensures clear visibility, day or night. This timepiece is water-resistant to 20 bar and also low-pressure resistant, reinforcing its suitability for demanding environments. It comes fitted with its original stainless steel bracelet. Fully inspected and authenticated by our in-house watchmaker, this timepiece is running well and ready to wear.
