Sinn (DE) 103 St – Ref. 103.035 – The Traditional Pilot Chronograph With English Day & Date On Your Choice Of Strap

“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 (which is the case with this watch here), is also available (for an extra charge) with a high-domed, scratch-resistance sapphire crystal glass with anti-reflective coating on both sides. If you wish to have this watch with such a sapphire crystal, contact us for a specific quotation. Select your choice of strap and do not hesitate to contact us for any questions you might have.”
