Designed for my childhood dream The overall reference to the 70's sports car case styling, it displays the time on the side of the watch. The time display uses a very clever method of using prisms to vertically project the hour and minute indicators so that it can be worn to check the time while holding the steering wheel of a car without turning your wrist. Vintage yet stylish design The 1970s were a time of change for the watch industry, a time when watches were no longer confined to tradition, and when the status of the "dress watch" was being challenged by the rising proportion of sports-inspired timepieces. On the other hand, against the backdrop of the "quartz storm", many manufacturers caught up with the trends of the times, and a variety of bold and creative quartz watches were produced, exploring the shape of the future of the watch.
