SJX Watches recently published an in-depth look at Seiko's prodigious and fabled 9F Quartz movements, which are now in their 26th year of production. And there's no question the 9F is a genuinely high-end movement that has taken decades of engineering to perfect. It's actually a remarkable feat of timekeeping when you think about it like this: the 9F will never lose or gain more than 10 seconds a year that's an absurd level of accuracy, and it laughs in the figurative faces of any mechanical movement on the planet. Take into account that every single 9F is assembled and decorated by hand, and it's pretty easy to understand why the high-precision quartz movement is found exclusively in Seiko's top-of-the-range Grand Seiko models. Anyway, if you're a fan of Seiko and Grand Seiko, or want to gain a better understanding of the engineering and production of Seiko's lauded quartz movement, this in-depth article is definitely worth a read, and you can check it out right here.
