Sinn 103 St Pre Owned – Valjoux 7750

Used but mint condition Sinn 103 St with Valjoux 7750 automatic movement. In mint condition, originally bought form us in 2012 comes complete with box and papers. The Valjoux model is now discontinued and the chronograph movements being used by Sinn is the Concepto C99001. The models in Sinn's 103 series make it instantly clear what these timepieces were created for: uncompromising functionality. Following company tradition, the design of these watches reminds one of the instruments in an airplane cockpit. After all, the first timepieces by the company's founder were mechanical airplane cockpit clocks for professional use. Model 103 St, which is equipped with a shock-resistance acrylic glass, is also available for an extra charge with a high-domed, scratch-resistance sapphire crystal glass with anti-reflective coating on both sides.
