Innovative Sinn brand solutions. Drying technology Ar and oil Hydro

This is another topic that I move in the book #czasnagłębokości



Since the 1990s, German Sinn has introduced very interesting solutions to his collection of diving watches. The company was founded in 1961 by Helmunt Sinn in Frankfurt am Main as Helmut Sinn Spezialuhren. The company specialized mainly in the production of navigational watches and chronographs for pilots. Sinn was also known for unconventional constructions. In the 1980s and 1990s, his watches even reached orbit around Earth on the wrists of German astronauts. In 1994, Lothar Schmidt bought the company from Helmuth Sinna, followed by a change of name to Sinn Spezialuhren GmbH and made a deep reorganization of the company.

In 1994, the manufacturer introduced in its watches a new type of anti-magnetic construction. It was a kind of protective "cage", shielding the mechanism and blocking the action of magnetic fields with a force of up to 80,000 Amps per meter (A / m), which corresponds to 1000 Gauss.

In 1995, Sinn developed a drying technology called Ar-Dehumidifying. For the first time it was used in a 203 Ti Ar dive watch. Its aim is to completely eliminate moisture from the interior of the case and consists of 3 elements:

• Drying capsules with copper sulphate that absorbs moisture.

• EDR gaskets that are four times more resistant to passing from standard rubber gaskets.

• Filling the case with a protective gas.

The new technology prevents the evaporation inside the case even in the event of a sudden change in temperature and effectively delays the aging process of the components of the watch, thus extending its life. Since 1998, Sinn has been using the Ar technology in conjunction with special lubricating oil 66-228, which ensured reliable work in the temperature range from - 45 to + 80 ° C.

In 1996, Sinn introduced a technology called Hydro in his diver watches. The first model in which it was used was Sinn 403 Hydro. The project was based on filling the watch with a specially composed oil that replaced the air. The oil used is crystal clear and has the same refractive index as sapphire glass. As a result, it was possible to completely eliminate light reflections, so the watch face was perfectly legible at all angles. Watches manufactured in Hydro technology are completely resistant to the condensation effect, which manifests itself through the misting of the interior of the glass. Another advantage of filling the case with oil is the fact that it is practically incompressible, thanks to which the structure is theoretically resistant to water pressure at any available depth.



Among other solutions used by this manufacturer, it is worth to mention the advanced rotating bezel (Captive safety bezel) introduced in 2008. Its construction prevents accidental breaking. The ring is also equipped with a patented lock, which is operated by two fingers. This guarantees virtually complete protection against accidental movement of the frame during standard operations. The lock starts automatically.

In 2015, the model UX S Combat Swimmer (EZM 2B) went to the equipment of German commandos from KSM (Kommando Spezialkräfte der Marine). Of all companies participating in the tender, Sinn Spezialuhren GmbH completely met the requirements. The watches were expected, among others optimal readability in the most adverse lighting and water conditions, resistance to seawater and high durability. The rotating bezel had to remain functional even when used in diving gloves.



Currently, the German manufacturer's offer includes dive watches with WR from 500 to 2000 meters. Since 2005, most of the Sinn divers have been manufactured from German shipbuilding. The watches pass tests based on European standards for diving equipment, and are certified by DNV GL.

The Sinna license has created watches, among others for the Bell & Ross brand. In the late 90s, the Hydro 8000 quartz model was created. The French brand appreciated the advantages of Hydro technology and soon their offer was complemented by the Hydromax Professional 11100 M. This model uses an oily liquid called Hydroil. The watch has been tested by the French Institute for Marine Research at a pressure of 1110 bar, which corresponds to a depth of approximately 11100 meters. This proves the high efficiency of this type of construction. Another brand that applies oil-filled cases is Ressence.

Helmuth Sinn died in 2018 at the age of nearly 102 years. His heritage is still being developed in the factory on the Main, and Sinn products are becoming more and more popular among lovers of solid watches.
