Sinn Flieger 856 S automatic pilot’s wristwatch. This is a modified version of its predecessor, the Sinn 656, which is one of Sinn’s best selling models. It is very similar in looks but has increased proportions as the older 656 was slightly on the small side. For those who prefer the smaller dimension, the 556 A is the same size as the older 656. The watch has been modified and upgraded to include a Tegimented case and copper sulphate water absorbing capsule. The watch case hardened using Tegiment technology provides extremely effective protection from scratches on the case surface. To achieve this, we do not apply any coatings of foreign materials; rather, the surface of the watch case itself is hardened in a special process. To keep the cases of Sinn watches in the best possible condition when they are worn, A Tegimented stainless steel case has a surface hardness of approximately 1200 Vickers. This value corresponds roughly to the hardness of commonly used zirconium oxide ceramics. By comparison, an unhardened stainless steel case has a hardness of approximately 220 Vickers. It also has Ar-Dehumidifying technology which solves a basic problem of mechanical watches: the aging of oils due to moisture in the air contained inside, or diffusing into, the watch. The movement is mounted in a nearly anhydrous atmosphere thanks to the three Ar-Dehumidifying technology elements of drying capsule, EDR seals and protective gas filling. Aging processes and fogging of the crystal from sudden cold are prevented, and reliable functioning and accuracy are ensured. A simple design, with 4 large prime hour numbers, jet black with white markings and hands gloving maximum visibility and clarity. The design is based on an aircraft clock. As well as being a lovely practical looking watch, it is highly functional and is extremely resistant to magnetic interference, and has a strong well finished crystal and case. There is a small date window between the 4 and 5 hour markings. It is small so not to interfere with the numeric symmetry of this beautifully designed watch. Sandblasted stainless steel case and bracelet. The watch features a Swiss made automatic Seletta movement working at 28.800 semi-oscillations per hour, Seconds stop function for accurate time setting, shock resistant as per DIN 8308, anti-magnetic as per DIN 8309, for protection up to 80,000 A/m. It has a screw down crown and case back, 20 ATM water resistance which is around 200 metres, black steel bracelet, stop seconds for accurate time setting, sapphire crystal with anti reflective coating presentation box, paperwork and 2 year factory warranty. Width is 40 mm at widest excluding crown and 44 mm including crown, Lug to lug is 47 mm, Thickness is 11 mm.
Key Characteristics
Additional Product Details
Sinn Watches was formed in 1961 by the legendary pilot and flight instructor Helmut Sinn. They began manufacturing flight watches based on his extensive aviation experience, this was primarily based on Mr. Sinn's dissatisfaction with the watches that were available for pilot and navigational purposes at that time. His own designs incorporated the features and functionality that he felt more fit for purpose as an instrument watch. This is a design philosophy that has transcended the company's culture right through to the present day. Sinn is now the world's most eminent manufacturer of high quality, precision, functional and purposeful instrument watches. From the beginning, their emphasis was on creating special purpose instruments that performed under extremely adverse operating conditions such as high speed, high and low pressures and altitudes, intense heat or pressure, extreme cold, high magnetic interference, and submergence in liquids. Sinn are becoming increasingly known for their instrument watches, and are today a force to be reckoned with as they lead the way in instrument watch design. The company changed hands in 1994 when Lothar Schmidt formerly of IWC assumed control and further expanded the boundaries of Sinn’s high tolerance manufacturing expertise. Over the past decade, Sinn has pioneered some innovative new technologies, including oil filled watch chambers to enable operation under extreme pressures, argon gas filled watches to prevent moisture infiltration, impact resistant gear suspensions, and new micro-lubricating techniques. Their timepieces are standard equipment in some of the most dangerous and adverse environments on earth - little surprise their watches are issued to the German military and elite forces. Above all the watches are manufactured and marketed to the world at large. Like the designs and their application areas, the pricing of the Sinn watches is most aggressive, making them available to most people. Due to distribution agreements Sinn watches can only be shipped to the UK and Ireland and certain countries where there is no Sinn agent assigned to that territory. Sinn watches are covered by a two or three year manufacturers warranty depending on the model.
