Some grails are special because of their association with history (see my piece on the “Scuderia Ferrari” Zenith, for example), while others are just plain odd. This is the latter. The Girard Perregaux Casquette (Ref. 9931) is a mid-1970’s LED quartz watch with innovations throughout. It’s just too bad the quartz revolution ended with a whimper instead of this kind of excitement!

Not everyone is into quartz watches. That’s understandable. But anyone who appreciates history and technology would be interested in the story of the first quartz watch. At the end of the 1960’s, which itself was something of a golden era for mechanical watches, two competitors raced to bring quartz clock technology to the wrist: Seiko won and came to dominate the market with low priced models.
