This is a watch of superlatives: 659 individual parts, including 71 jewels, an perpetual calendar, a perpetual moon phase display, a chronograph and a minute repeater, which alone consumed 50 000 development hours. The Grande Complication from IWC Schaffhausen qualifies as one of the most intricate mechanical wristwatches in the world and is the most complicated currently in production in Schaffhausen – a maximum of 50 examples are built each year.
The exquisite mechanism of the Grande Complication (ref. 3770) is packaged only in fine cases made of 950-standard platinum or 18 ct.yellow gold. There are three dial variants, one in yellow gold and two in platinum, with a modified dial and hands. In these three variants, the hours and minutes are indicated by Dauphine-style hands in the same colour as the case, and the remaining seven hands are slender bar hands.
The variation in yellow gold is highly refined. It has a silver-plated dial with golden indices. The silvered dial is now also available in a platinum case. Blue indices are used here as a visual contrast, and these harmonize beautifully with the blue small second and second stop hands and the hands of the minutes and hours counters. Both models are supplied with a black crocodile leather strap.
The colours of the third addition are very discreet. Here a black dial is combined with the lustrous shine of the platinum case. Even the moon phase display blends well into this harmony of colour. The choice of a black crocodile leather strap, or perhaps the solid platinum bracelet with its fine links, was a matter for the personal taste of the purchaser. Even with all this diversity of models, one thing remained same: no more than 50 consecutively numbered examples of the Grande Complication were made in the year 2003.
