📖 About the Bell-Matic

The Seiko Bell-Matic (introduced in 1966) was one of the very first automatic alarm wristwatches ever produced. Its Caliber 4006A movement represented a milestone in horological engineering, bringing mechanical complexity and daily practicality together in a bold, modern design.

The 4006-6000 remains one of the most collectible variants — praised for its elegant proportions, reliability, and unique “bell” sound when the alarm is triggered.
