Sinn EZM 7 S: The Mission Timer 7 Developed for the Fire Brigade

Sinn Spezialuhren has designed the Mission Timer (EZM) 7 S for use in the toughest conditions – it is particularly resilient to the penetration of water and dust, to scratches, temperature change and the influence of magnetic forces. Thanks to its colour-coded rotating bezel, the EZM 7 S is easy to operate, making it child’s play for people using breathing protection apparatus to set and read off key durations – from CSA to LPA.

Like other Sinn Spezialuhren diving watches, this captive rotating bezel can even be set when wearing gloves. The surface of the bead blasted stainless-steel case is hardened using TEGIMENT Technology, making it especially scratch-resistant. This TEGIMENT case surface also provides the base for the high-quality Black Hard Coating (PVD coating). This combined process results in a highly practical benefit: applying the coating to the hardened stainless steel dramatically reduces wear and tear of the coloured coating. 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 – also thanks to the technology used. For example, the Ar Dehumidifying Technology guarantees greater functional reliability and freedom from fogging, while temperature resistance technology ensures the functional reliability of the EZM 7 S from –45ºC up to +80ºC. A special limited edition of 300 EZM 7 S timepieces is being produced, each with an engraved limited-edition number on the case back.
