“Kinetic” watches contain an internal electrical generator operated by the kinetic movement of the user’s wrist. The generated electricity is stored in a rechargeable battery that requires replacement less frequently than the conventional cell battery in a quartz watch.

With Auto-Relay, the watch will, when not worn, operate normally for 6 months on a full charge, after which it goes into "sleep" mode for up to four years. The accuracy remains, but the hands stop, conserving energy, until, once the watch is put on again, the hands automatically reset to the correct time.

This Seiko Brightz Men's Kinetic Auto Relay Quartz Black Dial Watch SAGB005 5J21-0A80 is a stylish and functional timepiece. With a sleek black leather strap and a round, black dial, this watch is perfect for any occasion. It features arrow markers, baton indexes, a seconds hand, stop-seconds function, and a 12-hour dial. The watch is water-resistant up to 100 m (10 ATM) and powered by a quartz movement. The case is made of titanium alloy and has a polished finish. The bezel is smooth and fixed, with a silver color that complements the black dial. This watch is a great choice for men who want a reliable and fashionable accessory.  The 20mm wide black leather strap will fit up to a 7.75 inch wrist.
