Product description
Item number: 1755311
What this watch is made for is obvious at first glance: uncompromising functionality. The design principles are based on those of cockpit instruments, much in keeping with the manufacturer's tradition. After all, the manufacturer's first clocks were mechanical aircraft chronographs for professional use. The model 103 St Sa is predestined for adventure: it is waterproof to 20bar, resistant to low pressure at high altitudes, shock-proof and anti-magnetic. Elegant materials such as stainless steel, sapphire crystal glass and leather have been used to create the watch.
Practical technologies
Sinn has focused on nothing but mechanical watches ever since 1961. At the time, the company was known as "Helmut Sinn Spezialuhren". Customers then and today swear by the performance, ruggedness, longevity, quality and precision of these watches. Functionality comes first and foremost: aesthetics are subordinated to function. These watches all incorporate useful technological features. Owner Dipl.-Ing. Lothar Schmidt puts it like this: "Products need to speak for themselves." The company has been based in the Sossenheim district of Frankfurt since 2017.
