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.
