Sinn - 103 Ti Ar

The pilot chronograph 103 Ti Ar once again serves as proof of how first-class technology and functional design can unite to yield a true classic. The design principles for aircraft instruments served as inspiration for its development. This is no coincidence – after all, both professional pilot chronographs and aircraft cockpit clocks were the first timepieces our company made. The technical features range from the captive pilot’s bezel with minute ratcheting to the Ar-Dehumidifying Technology for enhanced functional reliability and freedom from fogging.

The bead-blasted case is made of pure titanium, which underlines the technical and contemporary interpretation of the watch and ensures a comfortable fit.
