Sinn EZM 7 – The fire fighters’ watch


EZM 7 – The mission timer developed for firefighters

Model: 857.030

The Mission Timer (EZM) 7 with its colour-coded bezel is easy to operate, making it child’s play 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 – like 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 TEGIMENT-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
  • Case with TEGIMENT Technology and therefore especially scratch-resistant
  • Nickel-free case back
  • Ar-Dehumidifying Technology for enhanced freedom from fogging
  • Magnetic field protection up to 80,000 A / m
  • Second time zone on a 24-hour basis
  • Captive bezel with minute ratcheting
  • Sapphire crystal glass
  • Crown at left at 9 o’clock
  • Functionally reliable at temperatures from -45 °C to +80 °C
  • Pressure resistant to 20 bar (= 200 m water depth)
  • Low pressure resistant
