Grande Complication Ref. IW3770

Grande Complication from IWC Schaffhausen: This exceptional achievement in the field of the watchmaker's art qualifies as the superlative among masterpieces. In spite of having 659 mechanical micro components, it is as easy for the wearer to operate as any other watch - this is called progress. Three new variants, one in yellow gold, two in platinum, are available with a modified dial and new Dauphine-style hands in a corresponding case colour. The gold variant has a silvered dial, and the platinum variants offer a choice of a black or silvered dial.
