Editor's Notes

The 'Big Pilot's Perpetual Calendar' is one of the most technically complex watches IWC SCHAFFHAUSEN has ever made - the complication, developed by Kurt Klaus in the '80s, ensures reliability through leap years and months of different lengths. Powered by a calibre 52615 automatic movement, this Swiss-made reference has a 'Racing Green' dial with moon phase, day, date and month counters. It's fitted on a durable webbing strap to match the black ceramic case.

We offer an eight-year warranty for all working parts and manufacturing faults for IWC SCHAFFHAUSEN watches. For more information, contact one of our experts by emailing
