Sinn Flieger EZM 7.

Sinn EZM 7 automatic fireman’s wristwatch. The design is based around timing functions used by firemen and other rescue servicemen which are critical toward timing required when fighting fires. As well as being a practical looking watch, it is highly functional and is extremely resistant to magnetic interference, and has a strong well finished crystal and case and contains all of the scales, colour coding and independent timing required for use when fighting fires.


With the colour coded bezel is easy to operate, making it easy for people using breathing protection apparatus to set and read off the relevant durations – from CSA to LPA. The captive bezel can even be set when wearing gloves, as they can do on Sinn’s diving watches. Sinn have designed the EZM 7 for use in the most difficult conditions . It is especially resilient to the penetration of water and dust, to scratches, changes of temperature and the influence of magnetic forces. The case with tegimented technology has a surface hardness of 1200 Vickers. And the sapphire crystal glass with anti-reflective coating on both sides and luminous indices ensures optimum readability by day or night. Ideal for heavy duty use by the fire brigade or rescue services.


Case made of bead-blasted Stainless steel , the case is tegimented and therefore especially scratch-resistant with an anti allergenic nickel free case back , it also has argon r-Dehumidifying Technology for enhanced freedom from fogging. It has magnetic field protection up to 80,000 A / m . It also has a useful second time zone on a 24-hour which is used as dual time movement. The UTC hand is independently settable so can be used as a GMT hand or a dual time zone hand. The UTC hand is greyed out so it does not interfere with the overall legibility of the watch if sued by firemen and rescue personnel under low light condition. The dial is matte black with super luminova luminosity providing a high level of legibility under low lighting conditions – essential for firemen and other rescue services.


The bezel is a captive bezel with minute ratcheting, it has an anti glare scratch resistant sapphire crystal glass. The crown is at the left side at 9 o'clock position making it more comfortable to wear as it does not dig into the wrist, more importantly from a practical view point, the crown will not snag on obstacles. The watch is functionally reliable at temperatures from -45 °C to +80 °C . It is pressure resistant to 20 bar (= 200 m water depth) and is also low pressure resistant for high altitudes. To assist with the pressure resistance, the watch has got a screw down crown. The movement is a 21 jewel Swiss made automatic winding caliber ETA 2893-2. It has got stopping seconds for accurate time setting. There is a small date window between the 4 and 5 hour markings. It is small so not to interfere with the numeric symmetry and the chart legibility.
