The present Classic Prisma Diamond Cold Cut Gold Face model was worn very carefully by its first owner. The watch shows minor but barely noticeable signs of wear. The battery was changed regularly, but the watch has been stored in a safe for years. The quartz movement has been checked by a certified master watchmaker and found to be in perfect working order. This extraordinary piece from Corum represents a combination of understated luxury and refined elegance. The prism sapphire crystal ensures perfect readability of the exact time, even though there are no hour markers on the dial. The focus here is on maximum reduction to the essentials.
