Grand Seiko is the fine watchmaking division of Japanese giant Seiko. So why does this watch have a battery-powered quartz movement inside? It’s no ordinary ticker — Seiko ages its own quartz crystals, then decorates and fine tunes the movement so it keeps time to within 10 seconds per year, so you’ll never be late for a meeting again. To a serious mechanical watch fan, the idea that any quartz watch might be something you’d call a value proposition – much less a quartz watch costing thousands of dollars – might seem ridiculous, but if you’re of a certain turn of mind there’s a kind of integrity and purity to be found in Seiko’s Grand Seiko quartz watches you won’t get anywhere else. Grand Seiko mechanical watches, of course, are generally considered by serious watch lovers to be one of the best things to happen to watchmaking since Huygens stuck a spiral spring on a balance, and Seiko Spring Drive is a reminder of Arthur C. Clarke’s adage that any sufficiently advanced technology is indistinguishable from magic – but quartz? What’s there to love about a quartz watch? If we look at the details of construction of the Seiko quartz caliber 9F we see a movement that is dramatically superior to an average quartz movement. First of all, if you are still preoccupied with in-house this is about as in-house as it gets; Seiko not only has its own semiconductor facilities, it also grows its own quartz crystals in giant reactors, and from the raw crystals selects only the most pure for Grand Seiko quartz movements. To avoid drift in rate due to aging, the selected crystals are aged for up to three months. Each crystal is individually tested for its specific frequency response to temperature change, and paired with an integrated circuit specifically programmed for that crystal. Once inside the watch, the movement actually samples the ambient temperature 540 times a day, and uses that information to adjust the frequency of the crystal to compensate.
