Grand Seiko is no stranger to high-grade, high-accuracy mechanical movements, and today’s Grand Seiko calibers are built on the brand’s storied heritage of mechanical excellence. Through an expert combination of traditional watchmaking and state-of-the-art manufacturing, Grand Seiko is able to make movements that are hard-wearing, reliable, accurate, and superbly finished.
First and foremost, it should be noted that Grand Seiko is a fully-integrated manufacture — they produce all components in-house. Located in Morioka, Japan, Grand Seiko’s Shizukuishi Watch Studio is where Grand Seiko’s mechanical watches are made from start to finish, beginning with the manufacture of individual components, and ending with casing, testing, and final inspection.
When I visited Japan, I had the good fortune of seeing Grand Seiko’s manufacturing facilities up close. They were highly impressive, and it was truly one of the more interesting manufactures I’ve experienced. I witnessed parts both big and small get machine-cut, and then I watched those parts get hand-finished by Grand Seiko artisans.
