The IWC Portuguese Grande Complication timepiece is a fascinating watch of horological complexities and impressive design. It contains the self-winding 79091 caliber, the same caliber that was released by IWC in 1990. Some of its features include a chronograph and a minute repeater, a perpetual calendar that also displays a four digit century indicator. All of these intricacies required 657 parts to be put together, thereby producing a timeless watch, which IWC says collectors will cherish as a new aesthetic identity for one of the world’s most prestigious mechanical watches.
The theme of the watch tends to be of exploration, with an imitation of a globe, with the longitudes and latitudes, appearing on the face of the watch. The multi-counting features render it a watch of discovery and adventure, and the classy design helps it retain the elegance the makers had in mind.
In addition to all of its mechanical functions and design features, the Grande Complication also boasts a case that is designed to be water resistant up to 30 meters. In general, minute repeating watches are not water resistant at all, due to their vulnerable slide piece. But IWC has always been a forerunner for this important distinctive characteristic. Even the predecessor of this watch was 10 meters water resistant which was unlikely at that time.
