IWC Schaffhausen 64900

The IWC 64900 is a hand-wound manual-winding caliber manufactured by IWC Schaffhausen, based on the ETA 6498-1. It features a fan-style display in place of the traditional small seconds hand, giving the seconds indication a distinctive sweeping appearance. The movement drives a large central seconds hand directly from the escapement, a construction that distinguishes it from conventional small seconds complications. The 64900 serves as the base for several IWC watches in their classic and pilot collections.
