Sinn Sinn Flieger Wristwatch 757 UTC 757 UTC
Sinn Flieger Wirstwatch 757 UTC
The Sinn 757 UTC is a variation on the existing 756 UTC, manufactured to larger specifications and with the addition of the bi directional rotating bezel. Apart from being a completely unique watch, designed like not other watch past and present, new materials and new technologies take these models to another level of design and robustness. The cases are steel distortion-free ice-hardened and reached with it a hardness of 60 HRC (Rockwell) and/or 710 HV. This corresponds to a three to quadruple hardness compared with normal nickeliferous high-grade steel. The new patented crown and pusher system of the 756 was designed to prohibit any moisture building in the case. The pusher seals sit one behind another and lubricated by a self-lubrication system almost makes the case impenetrable by water or moisture. The case does have a copper sulphate capsule which when reacts with moisture diffuses the humidity and therefore protecting the glass from condensation clouding. The jewels in the 756 7750 movement are lubricated with a special oil 66228 with a temperature range guarantee from minus 45 degrees to plus 80 degrees. The black on black emblem on the dial of the 756 at the 9 o'clock position is representative of the magnetic field core in the watch which symbolises the protection of the movement up 1000 gauss .The highly-regarded and precise Swiss Movement the Valjoux 7750 forms a sound base for the time keeping capabilities of this model . Also the high resolution dial with the anti reflective sapphire crystal glass guarantees good legibility in most if not all light conditions. Sapphire crystal, screw down crown and 20 ATM water resistant. Width is 43 mm excluding crown and 46 mm including crown Lug to lug is 52 mm, Thickness is 15 mm.
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.
