Sinn 358 Wristwatch DIAPAL

Brand new with 2 year warranty Sinn 358 Diapal. The 358 Diapal model was launched at the Basel fair in March 2011. To create the new Sinn 358, Sinn designed a brand new case in the style of one of the most popular watches, the 356, but with larger dimensions at their in house case making facility in Glashutte, Germany. This watch also features Sinn's dehumidifying technology which protects the movement oils from humidity and keeps the dial from fogging when moving from a hot to cold environment (such as an air conditioned room). This technology consists of three components - the use of inert gas injected into the case, which is argon gas. It also uses a copper sulphate capsule to absorb humidity and special EDR (Extreme Diffusion Reducing) seals to reduce the infiltration of moisture into the case. Sinn pays attention to small details, and in this case a problem that affects many watches as they age and are exposed to the sun. Just as UV radiation can damage the skin, it also can cause the dial color to fade and change colors over time. Sinn uses a special electroplating process to make this dial UV resistant and to preserve the charcoal grey color. It has got a sapphire crystal to the front and back and the front sapphire is domed. It is also pressure resistant, so will remain intact and working well under high pressures and sudden pressure changes. Sinn has modified the base movement to a new design. The modified Valjoux 7750 calibre is called the SZ05 and the main modification is to relocate chronograph registers to 3 and 9 to balance the dial display and make it more in keeping with vintage chronographs where this sub dial arrangement is regularly seen. The movement is beautifully decorated as one would expect for the 50 year anniversary model. Sinn also changed the function of the counter at 3 to create a 60 minute counter rather than the traditional 30 minutes seen on Valjoux automatic chronograph movements. The watch is 100 metres water resistant, Width is 42 mm excluding crown and 46 mm including crown, lug to lug is 49 mm and it is 16 mm thick. Ref. SIN 100a.
