Sinn Flieger Wirstwatch 757

The Sinn 757 is a variation on the existing 756, 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.
