Seiko Solar 100M Watch

Seiko is a world-renowned Japanese watchmaker with a history dating back to 1881. The brand is famous for introducing the world's first commercial quartz watch and for its continuous innovation in timekeeping technology, including the Solar-powered movement seen in this model.

While Seiko maintains high-end production facilities in Japan (Grand Seiko and Shizukuishi Watch Studio), many of its standard consumer models, like the Solar 100M series, utilize components or assembly lines across a global network. While the movements are often Japanese-made, case assembly and finishing may occur in Malaysia or China to meet global demand while maintaining strict quality control. The brand remains 100% Japanese-owned, operated by the Seiko Group Corporation.
