Watch movements are arguably the most important part of a watch: as the heart and brains of our timekeeping devices, you need to have a movement if you want your watch to work. Quartz watch movements are the new style of movement, they are built to last and come ready to install. These Hattori Japanese movements are Japanese assembled and are made to fit Seiko, Lorus, and Pulsar watch cases.
