For its tenth anniversary, this famed IWC chronograph has received a tenth hand. The original had nine, plus four subdials and a moon disc, providing the hour, minute, seconds, date, month, full year and phases of the moon along with totalling times up to 12 hours. The tenth anniversary version in platinum also includes a split-second flyback hand to capture split times. Fitted with a delicately worked silver dial, this exceptional timepiece is produced in a limited edition and individually numbered from i to 500. A more traditional, non limited version is also available in 18K gold.
