Watch Overview Available here is a Sinn Spezialuhren 104 St Sa I automatic pilot watch, reference 104.4740. The Sinn 104 takes its design from traditional aviation and instrument watches, with a highly legible dial and a rotating minute bezel that gives the watch its distinctive tool-watch appearance. Inside is the self-winding caliber SW220-1 with 26 jewels, operating at 28,800 vibrations per hour. It provides central sweep seconds, day and date displays, and a stop-second function. Made in Germany. The black dial has luminous baton markers and broad luminous hands, with a day/date window at 3 o’clock and a detailed minute track around the perimeter. The white markings and hands stand out clearly against the black background. The 41mm polished stainless steel case is fitted with Sinn's captive bidirectional pilot's bezel, which features minute ratcheting and a luminous triangular marker. Sapphire crystal protects the dial, while a second sapphire crystal on the caseback provides a view of the automatic movement and its gold-tone Sinn-signed rotor. It has a screw-down crown and 200-meter water-resistance rating. This example is paired with a brown leather strap. It has been inspected by our in-house watchmaker and is running and keeping time.
