For sale **Sinn 756S** it is Sinn chronograph, great tool watch made in Germany. **The case of the 756S is Tegiment-treated steel PVD-coated with titanium aluminium carbon nitrite (TiAlCN)**. This prevents the usual scratching and cracking prevalent in most PVD-coated watches since the hardness of the coating “blends into the base hardness of the case” Inside is valjoux 7750 modified by Sinn. Sinn lubricates 7750 inside with Sinn Special Oil 66-228, a “high-grade, fully synthetic oil” which **works at temperatures ranging from -45 °C to +80 °C** Dial is magnificent, this you like or hate. So simple and on other hand great to see. Condition is used, there can be seen some signs of use if you try to search for them, but for tool watch, nothing. Glass is good, there isnt visiable scratches on it. dial is perfect **Watch is serviced in 2020 by Sinn germany**. it works very nice. capsule on edge of case shows nice light blue color. (dark blue would suggest that moister inside is more then it would need to be, but with that it also can work for years before service). I will provide picture from timegrapher inside album for sale is watch, no box or papers. **Straps are almost new!** both purchased from Sinn with genuine buckles ofc. Dark brown and black one. together they have cost me apx 190usd. pictures: https://imgur.com/a/3xkf0Fo timestamp: https://i.imgur.com/77nVYm6.jpg Price:**1600$** paypal (FF or G&S +5%), shipment included in price, worldwide with DHL Express (from EU ) - trades inside EU, anything else must be something crazy interesting for me. The watches I sell are from my personal collection, I am a fan of watches, I often renew my collection by buying and exchanging watches with other collectors around the world.
