Hi guys! I'm selling today my unworn Sinn 103 st ou, with box & papers. I repeat the watch is NEW IN THE BOX. Sinn and Manufactum decided to join forces and came up with this limited edition Chronograph Tachymeter. Limited to 100 pieces only, and only available at Manufactum. The matt black dial has a very vintage look and includes a spiral shaped tachymeter scale on its dial. Although most tachymeter watches are able to measure speeds starting at 60 km/h, this Sinn Chronograph Tachymeter is able to measure speeds starting at 20 km/h.The case is made out of stainless steel and is water resistant to 200 meters (20ATM), has an acryl crystal (to keep its vintage look preserved) and a screw-down caseback and crown. This watch has a diameter of 41mm and a height of 15.5mm. Sinn’s & Manufactum’s Chronograph Tachymeter watch comes on a nice brown leather racing strap, and a green NATO strap is also included. The watch is for sale in other (well know) forum online (chrono 24) See here : watchestobuy.com and check for Sinn... they are selling a (preowned, not new) watch like mine at 3500 us$!!! asking price 2222 euros (negotiable) Thanks omegaforums for the place
