The company produces watch parts such as crystal oscillators and bearing jewels, but its watch movement manufacturing business has been transferred to Citizen Watch Manufacturing Co., Ltd.
In 2016 a large movement assembly factory (CWMJ Miyota Saku Factory) in [[Saku, Nagano|Saku]], Nagano Prefecture was opened. Most watch brands do not make their own [[watch movement|movements]] in-house, but rather use standard watch movements manufactured by specialized companies like Miyota and [[ETA SA]].
