The IWC Grande Complication is one of the most complex mechanical watches ever conceived. Its immensely intricate mechanism unites hundreds of tiny and perfectly interrelated parts in a sensational tour-de-force of high complications that celebrate the genius of the mechanical watch making crafts handed down through the ages.
Housed within the Grande Complication’s massive and elegantly contoured 42.2 mm yellow gold or platinum case, lies the phenomenal automatic-winding IWC 79091 calibre. Boasting a total of 659 parts and 75 jewels, this movement showcases a perpetual calendar with full century indication and synchronous moonphases, a chronograph function, and a minute repeater which chimes the hours, quarter hours, and minutes – upon request, whenever the slide lever on the left side of the case is activated.
Meticulously tuned gongs arranged around the periphery of the movement – in conjunction with the generous case volume – ensure that the chimes are an easily audible delight to the ear. The perpetual calendar is remarkable in that all of the calendar displays (day, date, month, and year) – as well as the moonphase – advance simultaneously via the crown, making adjustments a simple matter should the watch be put aside for a time.
The IWC Grande Complication watch is as stunning aesthetically as it is mechanically. Available in 18K yellow gold or in platinum, on either a massively crafted matching bracelet or a crocodile strap with deployant clasp, the Grande Complication has a meaningful presence on the wrist; lovingly executed details such as the gently inset subdials, or the sparkling moonphase disc made of goldstone, enchant its wearer. Above all, classicism is the predominant theme of this very special watch; the silvered dial, available on both the platinum and the gold versions, or the striking ardoise grey dial which is an option only for the platinum Grande Complication, ensure that this incredible timepiece radiates impeccable understatement and ageless good taste.
