Sinn 140 St SZ01 Space Chronograph Ref 140.020 Full Set

Founded in 1961 by flight instructor and former WWII pilot Helmut Sinn, the Sinn Watch Company began developing both pilot chronographs and navigation cockpit clocks.  Helmet Sinn’s mission was to produce timepieces that were durable in extreme conditions.  In 1994, the company came under the direction of Lothar Schmidt, who has been the driving force behind the engineering and technological advances that Sinn has implemented in their watch-making techniques that continue today.

The 140 St SZ01 features a 44mm bead-blasted surface-hardened stainless steel case with a sapphire crystal.  The 140 St incorporates Ar-Dehumidifying Technology to increase the functional reliability and prevent fogging.  The black dial features an interior pilot’s bezel, lumed hour markers, sub-dials at the 6 and 9 o’clock positions, a date window at the 3 o’clock position, lumed hour and minute hands, an orange running seconds hand, and an orange chronograph “jet” hand. Powered by the in-house Caiber SZ01 movement, the 140 St features a 42-hour power reserve and a water resistance rating of 100 meters.

This Sinn 140 St SZ01 Space Chronograph includes the outer and inner boxes, the warranty card, the strap changing tools, the manual, and the original Sinn bead-blasted surface-hardened bracelet.
