It is a mechanical watch movement powered by a spring. Mechanical watches need regular wear to keep them powered, and they may need occasional servicing to ensure optimal performance. Seiko automatic watches work on an automatic winding mechanism.
We suggest that you have your watch professionally checked every 2 to 3 years to make sure that the case, winding mechanism, gasket, and glass are in good condition.
