Sinn

For the last 44 years everything at Sinn has revolved around high-quality mechanical watches. This brand’s history began in 1961 when pilot and flight instructor Helmut Sinn began to manufacture pilot’s watches under his own name in Frankfurt-Rödelheim.

These were exceptionally instrumentlike wristwatches and board clocks of high functionality, fulfilling the professional demands of pilots perfectly. He sold them directly from the factory without using any type of middleman, and he didn’t advertise either. High functionality,top-grade indestructible quality,and extreme cost-effectiveness quickly got around the pilot scene. And today these unique qualities remain typical of Frankfurt’s Sinn brand.

Sinn has long been an insider tip among fans of mechanical watches, for together with the renaissance of the mechanical wristwatch,interest in these special watches originating in Frankfurt also rose. Specialties of the house such as instrument-like chronographs and sports and diver’s watches were able to assert themselves in trade press comparison tests against often much more expensive competition bearing “bigger”names.

Despite all of the brand’success, this also turned out to be a phase of new beginnings: At the age of 78 the brand’s founder and name-giver sold  both the company and the rights to the brand to Dipl.-Ing.Lothar Schmidt in 1994. A native of the German state of Saarland, Schmidt had been proxy holder,production manager, and one of the developmental engineers of the noble Swiss brand IWC until that point. He provided his new company with competence and knowledge as well as experience in development, production,and the introduction of new technologies – decisive impulses for continuing development. A myriad of technical innovations that made the trade and a growing number of customers perk up their ears followed: An anti-reflective diver’s watch absolutely condensation-free, made of stainless steel that could reach any possible diving depth thanks to the HYDRO® technology; a valuable chronometer-chronograph encased in a newly developed 22-karat gold alloy making it hard as stainless steel; a chronometer containing magnetic field protection twenty times higher than the norm and a movement suspension system that is exceptionally shockproof; models with ideal protection against movement corrosion filled with inert gases and outfitted with an integrated dehumidifying capsule; the development of timepieces for the professional use of police and border patrols (EZM models); lubrication and tolerance technology that allows a mechanical watch to function at temperatures from –45 °C to +80 °C. Our model 303 KRISTALL withstood a fire and ice test in 1998 during the dog-sled race Yukon Quest taking place in the icy expanses of Canada and Alaska where temperatures of –40 °C are not rare.The model 203 ARKTIS followed suit in 1999. This diver’s chronograph passed its test in the Arctic Ocean with flying colors. One of the newest developments by Sinn is the DIAPAL technology, containing expressly chosen materials for the watch’s most important governing components so that they no longer need lubrication. This technology premiered in our anniversary model, the Frankfurt Finance Watch made of a white gold and palladium alloy, on the occasion of our company’s fortieth anniversary in the year 2001. Further models featuring DIAPAL technology are the new 756 DIAPAL and the Frankfurt Finance Alarm Watch, model 6066. 

Watch Community opinion (by www.watchfinder.com):

Sinn was one of the best-kept secrets among watch fanatics for years until about 2002, when the brand caught fire on the Internet. Widely perceived to be a new brand, Sinn has been making watches for professional use in Germany for almost 20 years. Stories abound about people flying to the Sinn factory in Germany and buying 20 or more watches, and then selling them to their collector friends and/or on eBay. Now Sinn is more widely available, and to their credit, prices are still low compared to the high quality. Popular models include the Sinn 356 pilot's chronograph, Sinn 956 Rallye chronograph, Sinn EZM models, Sinn 103, Sinn 144, and the Sinn 903 which is inspired by the famous Breitling Navitimer.

Base movement: top grade Valjoux 7750 which Sinn has modified to create their SZ-02 calibre. The primary modifications consist of a redesigned minute register which actually counts 60 minutes rather than the typical 30. This register has been enlarged and is placed at 6, with the primary hour register located at 12. Next, Sinn has used its special oil to construct the movement. The Sinn special oil, also known as Sinn 66-228, permits a greater range of operating temperatures from - 45є C to + 80є C - in other words, this watch will hold up in extreme conditions. To counter the affects of moisture and humidity, Sinn has applied their "Dry Hold" technology to this model, consisting of four copper sulphate capsules and the use of inert gasses sealed within the case.

Dial: Black

This watch features a brand new bezel design from Sinn. First, the bezel is attached to the watch with screws rather than friction mounted. These screws prevent the bezel from becoming detached through accidental contact with other objects. Next, the bezel is locked in place and will turn only if downward pressure is applied. This "lock and push" system ensures that time sensitive events (such as dives) will be correctly measured.

Water Resistance

Next, a discussion of water resistance. This watch represents a breakthrough on the testing of chronograph functions at great depths. The watch is not only rated water resistant to 1,000 meters, the pushers and other chronograph functions have also been tested to that depth. Each Sinn U1000 S watch ships with a certificate from the international testing lab Germanischen Lloyd certifying these tests.

Sinn has developed a special system of double Viton® seals and other engineering processes to achieve this certification. While building a 1,000 meter dive watch is not in itself unique, building a diver's chronograph whose functions have been tested at that depth is an achievement.

Sinn has been hard at work over the last year to develop two watches that feature a Tegimented bezel, case, crown and case back, the first of which is the new Sinn U1000 and the second this watch.

The new Sinn U2 Black is constructed from the same steel that is used on the outer hull of submarines. The steel was procured by Sinn from a steel supplier to Emden GmbH, one of Germany’s North Sea shipbuilding yards who construct submarines. This submarine steel is not only extraordinarily sea water resistant (PRE value up to 38), it also possesses the highest anti-magnetic quality. 

Next, the Sinn U2 Black features a completely Tegimented case, bezel, crown and case back. Standard steel used by most watch companies has a hardness of between 200 and 240 HV (Hardness Vickers is a common scale used to measure material hardness). The Tegiment layer on this watch in combination with the PVD coating has a hardness in excess of 2,000 Vickers which is more than nine times harder than standard steel.

The technology and design elements used to create the new Sinn U1 go far beyond standards used at most watch companies. 

The U1 is designed to be virtually impervious to water penetration. The U1 case is made from the same steel that is also used in the construction of the outer hull of submarines. The steel was procured by Sinn from a steel supplier to Emden GmbH, one of Germany’s North Sea shipbuilding yards who construct submarines from the very same steel. This submarine steel is not only extraordinarily sea water resistant (PRE value up to 38), it possesses also the highest anti-magnetic quality. 

Because of the special steel used from the submarine steel manufacturer, the case resists the effects of exposure to salt water and salt water environments. Tegimented bezel.

The uni-directional ratchet operated rotating bezel is also milled from this submarine steel. The indices are machined directly into the bezel without the use of bezel inserts, which can corrode or come loose at deep depths. The international testing lab of Germanischen Lloyd has tested the U1, and determined that the watch can be certified as water resistant to 1,000 meters. This same firm tests submarines for their ability to withstand the effects of underwater use.

The watch has an automatic mechanical movement, operating at 28,800 beats per hour, shockproof according to DIN 8308 specification and anti-magnetic according to DIN 8309 specification. 

Matte black dial with date at 3, Super Luminova on hands and markers, and striking red seconds hand complete the design. Other features include sapphire crystal with anti-reflective coating, and rubber strap with double push deployant buckle and fliplock safety clasp.

Sinn 6100 Jubilee Regulateur Rose Gold Limited Edition

The 6100 Jubilee rose gold model reflects our self-conception and the Sinn corporate philosophy down to the last detail. It is without doubt the top of the range of classical masterpieces. As a valuable collector’s piece, it is strictly limited to just 45 watches. The elegant watch case is made of 18 ct rose gold. This creates a striking contrast to the jet black, guilloche-embellished dial. The front crystal and see-through back are both anti-reflective, for optimum legibility and a clear view of the working mechanism. The crown is sealed with the Sinn D3 crown system (direkt-doppel-dichtend in German, which translates as ‘direct double seal’). The Model 6100 Jubilee is water-resistant to DIN 8310, withstands pressure up to 10 bar (corresponding to a depth of 100 m) and is unaffected by low pressure.
