Sinn 857.050 description
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 the 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.
