About Sinn

Founded in 1961 by former pilot and flight instructor Helmut Sinn, the company Sinn-Spezialuhren embodies German expertise in mechanical mounts and movements. The Frankfurt-based brand first designed aviation watches and onboard clocks. Quickly, the quality of its watches enabled it to go beyond the borders of this very specialized environment to reach all audiences, starting with watch enthusiasts. 

Today, Sinn continues to equip some of the German army, particularly the police and customs officers, with formidable chronographs that embody simplicity and sober elegance. German enterprise has made remarkable forays into the field of high-end timepieces, with a collection of classic masterpieces that envy the big Swiss names in the haute horology world. If you are looking for the best deal, we recommend that you consider a preowned Sinn watch.

History Of Sinn Watches

During the 1950s, before the Sinn-Spezialuhren company was founded, Helmut Sinn began to make sketches of the modifications that he would make to watches worn in the aeronautical sector that existed at that time, influenced by his own aeronautical experience.

Shortly thereafter, he began designing watches and had them manufactured by Guinand, a Swiss company located in Les Brenets with a lot of experience in chronographs. For this reason, we can say that Helmut Sinn began to sell his first watches in 1953, several years before the establishment of the company that bears his name. With all this experience, Helmut Sinn took a step forward and in 1961 officially founded the Sinn-Spezialuhren watch company in Frankfurt, Germany. 

From the start, the company used a direct distribution channel and sold directly to its customers. This was a big advantage over its competitors; without intermediaries, Sinn watches could be offered at a much lower price than other well-known brands that used traditional distribution channels. In the 60s, Helmut Sinn was also involved in the world of motorsport, specifically the world of F1. He lived through the days of the great Fangio and his Maserati. At that time, in collaboration with the legendary Jack Heuer, a special edition of the Sinn / Heuer Rally chronometer came out. It was a highly valued, coveted piece since only about 400 units were manufactured.

Then, in 1985 the first automatic manning watch in space was the Sinn Chronograph 142. This was a landmark achievement for the watch company, proving that a watch with an automatic Sinn movement works perfectly in zero gravity.

In 1994, Helmut Sinn, with a heart condition and being almost 80 years old, decided to sell the company to Lothar Schmidt. However, Helmut Sinn did not leave the watchmaking scene. In 1996, he bought the Swiss company Guinand and established his headquarters in Frankfurt. The man was already very close to the brand since Guinand had been producing watches for Sinn since the 1960s. Helmut Sinn remained the owner of Guinand until 2014. This legend of the German watch industry passed away in 2018 at the age of 102.

Technologically speaking, the sale of the company to Lothar Schmidt marked the beginning of a new era for Sinn. On the other hand, it also represents a before and after in the philosophy of the brand, diluting the original that was so closely linked with the personality of Helmut Sinn. Since then, Sinn has multiplied its patents, including Ar-Dehumidification technology and hydro technology, or Diapal and Tegiment technology. 

The distribution channel has also been changed and the company now sells its watches no longer exclusively through direct sales, but also through jewelers, dealers, and specialty stores. The name of the company has also been changed; it is now called Sinn Spezialuhren GmbH. Currently, around 14,000 watches from the brand’s eight product lines are sold each year and originate from Römerberg, in the heart of Frankfurt. The diversity of its technology allows Sinn to manufacture models that are increasingly technical, strong, and equipped with new functions designed for everyday life.

Top reasons to buy a Sinn watch

Made in Germany - Not only Swiss manufacturers can produce watches with great precision. The Frankfurt company Sinn proves this fact. Since 1994, Sinn watches are manufactured entirely in local production facilities in Frankfurt. German watchmakers and German-made watch parts create real competition for the best in the business.

The fascination of aviation – Founder Helmut Sinn was a pilot and flight instructor, and with his expertise the brand’s aviator chronographs became legendary. Located in the city with the fourth largest airport in Europe, Sinn also manufactures cockpit instruments.

Special watches - Reliable and especially robust special watches, Einsatzzeitmesser (EZM) were developed by Sinn in 1997 for the German Federal Police and German Customs. Today, professional users rely on these accurate and functional instruments, including emergency physicians, pilots, firefighters, Bundeswehr (German Army) special forces and federal police (such as the GSG 9 of the special unit), the command of the special forces of the KSM of the Navy, and the special unit of the German customs administration ZUZ.

Technical knowledge - Lothar Schmidt, who has been running the company since 1994, brought a wealth of experience. Previously, he worked at IWC Schaffhausen, where he was responsible for the production of boxes, bracelets, and straps. As the main manager, he later headed production engineering for A. Lange & Söhne. All of his accumulated experience was included in the restructuring Sinn Spezialuhren.
