IWC has integrated a patented constant-force mechanism into a tourbillon. The tourbillon devices are applied to IWC Ingenieur copy watches with hand-wound mechanical movements. The constant-force tourbillon can keep the frequency of the balance absolutely constant, so the time can run very precisely.
The diameter of the cases is 46mm. The hour markers are black indexes with red gold settings. The central two hands show the time. There are three sub-dials on the black dial. A see-through sub-dial with a constant-force tourbillon at 9 o’clock also can show the seconds. Another sub-dial is designed to display double moon phrases with countdown function. The moon on the watch depicts the surface of the real moon very realistically. The other sub-dial is a power reserve indicator between 4 and 5.
IWC fake watches with black alligator straps are carried with Cal. 94800, self-manufactured movements with 43 jewels. The movements are strong to support many complicated functions. The power reserve is approximate 96 hours. Their backs are transparent, so more details about running movements can be seen. The complicated and unique watches are suitable for male fans.
