Notes

After 7 years and over 50,000 hours in the making, the IWC Grand Complication model was completed and presented in the spring of 1990. Kurt Klaus, the head watchmaker and technical designer of the brand strived to create the fi rst wristwatch-sized Grand Complication with unprecedented number of complications. With over 659 individual parts, the watch houses an impressive number of complications: perpetual calendar calibrated for 500 years, precise moonphase indicator, chronograph up to 12 hours, and a crystal clear chiming minute-repeater. Nevertheless, Klaus wanted to keep the watch more ?user-friendly? by choosing an automatic winding method fi t for daily use.
