Sinn 103 B more than just a Pilot's Watch
His connections to Breguet and Mathey-Tissot, whose owners Helmut Sinn knew very well from the airfield, were crucial for this model series.
Inspired by cockpit clocks in airplanes and designed for pilots, the Sinn 103 B models with Valjoux caliber 726 were created in the 1970s.
These models corresponded to the design and style of the pilot watches of the Breguet Type XX of the 2nd generation and its civilian version. The first Breguet Type XX models were assembled by Mathey-Tissot for Breguet.
