By TLex This one's not specifically a dive watch, but it's a very interesting watch which uses many of the same technologies that Sinn use on their actual divers and is rated to 200m; in many ways it reminds me of the EMZ 4 . . .
From SINN 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 our diving watches. We 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.
