Top Facts about Sinn Special watches

Fact about sense: Frankfurt financial center watch
Even if Frankfurt am Main is a rather atypical location for the watch industry, Sinn Spezialuhren is still located there. In 2017, after more than 30 years, the brand changed its domicile and moved from the Rödelheim district to Frankfurt-Sossenheim. Sinn Spezialuhren expresses its closeness to the city with its own watch model. In 1999 the brand launched a classically elegant watch with the words 'Frankfurt am Main'. The customers, mostly enthusiasts of technical watches, also wanted a so-called 'suit watch' from the brand they trusted. Sinn Spezialuhren took this big step - from the point of view of the time - with the Frankfurt financial center watch 6000.


In 2019, 20 years later, the Frankfurt-based company celebrated this success story with the 6012 model . The steel Frankfurt financial center watch with a full calendar has a moon phase display showing a mother-of-pearl earth satellite. All functions are powered by the automatic caliber SZ06 , a Valjoux 7751 , in which a 60-minute instead of a 30-minute counter is installed. The 41.5 millimeter watch is water resistant to 100 meters.

Fact about sense: One-time testing
Watches have been made from seawater-resistant submarine steel since 2005. The Sinn U1 and the Sinn U2 were the first diving watches made from this material and were tested and certified by Germanischer Lloyd (now DNV GL). This world's largest safety classifier for shipping tests Sinn diving watches rafiqsonsonline.com/product-category/daniel-klein/ for pressure resistance and water resistance. Since 2006, these diving watches have been considered part of diving equipment and have been checked and certified in accordance with European diving equipment standards. This process is unique in the watch industry. In 2020, Sinn brought out the 41 millimeter U50, a three millimeter smaller version of the U1.

Fact about sense: The world's first TESTAF-certified watch
Selected pilot's watches have been certified according to the Technical Standard Pilot's Watches (TESTAF) at the FH Aachen since 2012. It is the result of a joint research project initiated by Sinn Spezialuhren and ensures that a pilot's watch is qualified for professional use. The EZM 10 is the world's first TESTAF-certified watch, but it is no longer available from Sinn. Also noteworthy is the model's SZ01 movement rafiqsonsonline.com/product-category/royal-london/. It was designed on the model of the Lemania 5100. The SZ01 has a jumping 60-minute stop hand from the center. This ad is rarely found today.


On the initiative of Sinn Spezialuhren, the first pilot's watch standard, DIN 8330: "Time measurement technology - pilot's watches" was developed. This transfers the high demands placed on the equipment of airplanes and helicopters to wristwatches. It is ensured that a wrist pilot's watch can completely replace the time measuring instruments available in the aircraft for the pilot.
