IWC Grande Complication

The IWC Grande Complication has 659 mechanic pieces, among them 71 rubies. It counts with 17 functions and 12 patents, a perpetual calendar that will indicate the date for the next 500 years and the perpetual moon-phase display in polished gold. In the IWC Grande Complication, a chronograph and a highly complex minute repeater with an all-or-nothing piece slide work inside. This IWC'S wonderful invention chimes the time out the time in crystal-clear tones that are activated by the slide on the left-hand side on the case. The case, too, finished in solid platinum with a fineness of 95 percent or 18 ct. yellow gold, is first class. Despite the complex design of the case, the IWC Grande Complication is unaffected by superficial water splashes.
