subject: IWC in the watch history [print this page] Only in respect of mechanical watch movement is concerned, there are a lot of features, in addition to circular escapement fork, nickel board and bridge plate, the reprovision some cases, sub-display, central seconds hand, stop second hand engine performance, date display Fast adjust date performance, the balance wheel frequency of 28,800 times per hour vibration (Zhoushuai 4 Hz), with 28 jewels, power reserve 44 hours a superb sound performance. Moreover, the 80110-type movement with excellent results peri ton large woodpeckers drum on chains two-way device (pellaton winding ratcheted system), not only inherited the tradition of engineer series half a century and more to the table five years of strong plant experience in interpreting the concept of tab, so this self-winding movement as similar works which, operating performance of the best, most solid protective equipment, technical structure, the most reliable, operate using the most simple masterpiece. 80 110-type movement also has a characteristic: its anti-magnetic. After testing, each meter can be as high as 80,000 a / m 80,000 amps, substantially more than the Swiss anti-magnetic sheet standard 4800 amperes. Movement inside with soft steel, to form a complete conduction magnetic field, to avoid polarization effects. The production of anti-magnetic inner layer of the earliest engineers with the same watch, with soft iron sets, movement rings and links back to board.
