Sinn Spezialuhren is a German watch manufacturer known for producing military and dive watches with leading-edge materials. Sinn watches are mainly sold direct-to-consumer at more-affordable prices than German or Swiss competitors. The company was founded in 1956 by aviator and racing driver Helmut Sinn, who managed the firm into the 1990s before turning it over to former IWC engineer Lothar Schmidt. The company today claims to be founded in 1961, but the company celebrated 25 years in 1982, suggesting the earlier date.

Foundation by Helmut Sinn

Helmut Sinn was born in 1916 in Metz, then part of Germany. He served as a Luftwaffe pilot and trainer during World War II and became a rally race driver in the 1950s. Seeking an entrepreneurial opportunity, Sinn began selling cuckoo clocks to Americans stationed in Germany.

In 1956, Sinn founded a company under his own name to import and sell clocks and watches in Frankfurt. He initially focused on Heuer chronographs and stopwatches, which were connected to his life as an aviator and driver. The company soon began using the term "Spezialuhren" to differentiate its products from the ordinary watches and clocks offered by competitors, and this name has been used by the firm ever since.

Seeking to expand his business, Sinn established a branch in Switzerland in 1965. Initially located in Zürich, the branch was moved to Berne and then La Chaux-de-Fonds as his local representative, Dr. Adolf Léon Benz of Winterthur, moved his own offices. Sinn watches were produced in Switzerland by established firms according to Helmut Sinn's specifications.

In the 1960s and 1970s, Sinn's firm became involved in the repair and refurbishment of Heuer and Leonidas chronographs used by the Bundeswehr. The company soon began customizing these watches for military use, developing their own variants to supply military contracts. Among the most collectible are the so-called Heuer Bundeswehr Chronographs, which were modified by Sinn and feature unique dial elements. In the 1980s Sinn began selling refurbished Bundeswehr chronographs to the public. Sinn and Heuer developed a prototype automatic chronograph for the Bundeswehr using the Chronomatic movement, with Gerd Rudiger Lang (later founder of Chronoswiss) involved in the rejected project.

Sinn also supplied dashboard clocks for aircraft during this period, including the Luftwaffe. Another specialty for Sinn was watches for the blind. A 1982 mention in Europa Star clarifies that the company was then 25 years old (dating it to 1956 rather than 1961 as sometimes claimed) and shows an unusually large wrist stopwatch.

In 1979, Sinn purchased the remaining stock of watches and components of Breitling. This gave the company a base on which to build the development of their own watches. The company was famous starting in the 1980s for practical and tough watches for military and civilian aviation, diving, and timing.

The Sinn 142 chronograph, introduced about 1980, featured the automatic Lemania 5100 movement and would become an icon: In 1985 a Sinn 140 S automatic chronograph was worn by German astronaut Reinhard Furrer on the Spacelab station. Sinn watches were also worn on the Mir '92 and Columbia space shuttle missions. When Lemania wanted to cease production of the movement in the late 1990s, Sinn pressed them to continue production, which they did until 2006.

Sinn pioneered the direct-to-consumer sales model in watches, issuing catalogs and fulfilling orders by mail. The brand became famous for producing high-quality watches at affordable prices. Though it never gained much broad awareness, Sinn was respected especially by dive watch enthusiasts. Among the products offered by Sinn was the Sinn 156, a modern reinterpretation of the Heuer Bundeswehr Chronograph using a Lemania 5100 movement.

When two French designer and Sinn intern Bruno Belamich wanted to establish his own watch brand with his friend Carlos Rosillo, he turned to Sinn. The resulting watches wore their new brand, Bell & Ross, but also proclaimed "by Sinn" on the dial and were very close to Sinn's own offerings, including the famous Sinn 156. The pair had recruited Lothar Schmidt from IWC to lead their efforts, and he was impressed by the possibilities of the Sinn brand.

Transformation under Lothar Schmidt

In 1994, the 78 year old Sinn sold his eponymous firm to former IWC engineer and Bell & Ross lead Lothar Schmidt. He had intended to continue working with the firm, but the two soon had a falling-out and the company continued without its founder.

Lothar Schmidt moved the brand forward with new inventions and technologies to improve the durable and robust watches produced by Sinn. Shortly after he took over, Sinn introduced the Sinn 244, a shock- and magnetism-proof watch in a titanium case. Sinn also added the brand's first gold-cased watch, a chronograph with a special 22-carat alloy said to be as hard as steel.

The Ar-Deumidifying technology was developed in 1995. It uses a special copper sulphate drying capsule, extreme diffusion-reducing (EDR) seals, and protective Argon gas filling to prevent humidity inside the case. This was introduced in the 203 Ti Ar dive watch, and is now widespread in the company's range. Another major advance was 1996's HYDRO, a technique that fills the case with a clear non-compressible liquid with the same refractive index as sapphire glass, eliminating fogging. In 1997 Sinn introduced the Einsatz-Zeitmesser 1 (EZM1) mission timer, a stripped-down Lemania 5100 automatic chronograph with no subdials or windows and a left-side crown and pushers. This was paired with the EZM2 line, which used the HYDRO technology. A year later the 303 KRISTALL became the most temperature-insensitive watch thanks to Ar and a special oil. Sinn won its first Goldene Unruh award in 1998 for the 103 Ti Ar.

In 1999, Schmidt founded Sächsische Uhrentechnologie GmbH Glashütte (SUG) in Glashütte. This specialized case manufacturer focuses on advanced case designs and materials.

Also in 1999 Sinn introduced the upscale Sinn Frankfurt Financial District Watch series. These feature advancements in movements as well as sophisticated design suitable for dress use.

Another, now patented invention of the Sinn research is a completely oil-free Swiss lever escapement. In addition, they developed a special heat-resistant oil that can even accomplish its task at an extreme temperature range between -45 degrees and +80 degrees Celsius. Also in the field of magnetic field protection and scratch resistance of case materials (tegimentation), Sinn offers new solutions.

Sinn manufactures navigation on-board clocks under the brand name Sinn NaBo® and chronographs (SZ01 based on the Valjoux 7750). Another well-known watch range by Sinn includes the EZM series (Einsatzzeitmesser or mission timer) for police, federal border guard, fire brigades and rescue services.

Also there is, matching to the company's headquarters in Frankfurt on Main, the Frankfurt Financial District Watch (Finanzplatzuhr).

Newer models are the Taucherchronograph U1000 (diver's chronograph) with a case in tegimented submarine steel, the expedition watch 900 Hummer (Chronograph) and the Regulateur 6100, which with his technical style is purposely simple and straightforward in contrast to many traditional regulator watches.

The case manufacturer SUG

The Sinn Spezialuhren GmbH & Co KG contributed significantly to the foundation and establishment phase of the Sächsische Uhrentechnologie GmbH Glashütte (SUG) (Saxon watches technology) by the allocation of commissioned production of cases. In addition, there is a lively and fertile, close technology transfer between the two prosperous companies in Frankfurt and Glashütte.

The Sinn Catalogue book

Sinn generously offers to any interested watch friend the opportunity to send the current catalog for free. Unlike other catalogs available on the watch market, this one is a real, comprehensive hardcover book that is not also written in the usual style of self-commendations, but - committed to the restrained and modest, no-nonsense style of the company owner Lothar Schmidt - has to offer a wealth of interesting information and in part reads like a textbook. To anyone who is interested in mechanical watches at all, the reading of this book is strongly recommended.

The Sinn Sales Partners

In addition to direct sales, where you get the watches ordered directly from Sinn by post and to your view, in recent years there has been built an increasingly dense network of so-called "deposits". These are watch shops that have a part of the total supply of Sinn watches in stock. Of course, for the interested watch enthusiast, if he is nearby, this is the best way to get oriented on the spot.
