Founded in 1881, Seiko began as a humble jewelry and clock store and has since grown into the watchmaking juggernaut that it is today. If the technology for a watch they wanted to make didn’t exist, Seiko made it happen under their own roof. Since Seiko is vertically integrated, they can customize nearly any part of their watches to their own design and specs in house. From the first true dive watch, to one of the first automatic chronographs, and completely new ways of powering a watch like Spring Drive, Seiko’s list of horological achievements is lengthy. They’ve done everything all the way down to creating their own lab-grown and regulated quartz crystals for timekeeping.
