Seiko 5 Sports Watch - Blue Dial

An automatic movement is a mechanical watch movement that winds itself through the natural motion of the wearer's wrist. It does not require a battery, relying instead on a rotor that spins with movement to tension the mainspring.

Mechanical watches, including automatic ones, are not as accurate as quartz watches. The Calibre 4R36 movement typically has a rated accuracy of -35 to +45 seconds per day under normal operating temperatures. Actual performance can vary based on individual wear patterns and environmental factors.

Yes, with 100 meters of water resistance, this watch is suitable for swimming, showering, and general water sports. However, it is not designed for saturation diving. Always ensure the crown is fully pushed in before any water exposure.

While Hardlex is impact-resistant, it can still scratch. Avoid direct contact with abrasive surfaces. If minor scratches occur, specialized polishing compounds might help, but deep scratches usually require crystal replacement by a professional.

No, the Seiko 5 Sports (SRPD51K1) features an automatic mechanical movement (Calibre 4R36) that powers itself through wrist motion. It does not use a battery.

Lumibrite is Seiko's proprietary luminous paint that absorbs light energy from sunlight or artificial light and stores it to emit light in the dark, providing excellent readability in low-light conditions without radioactivity.

It is generally recommended to have automatic mechanical watches serviced by a qualified watchmaker every 3 to 5 years. This servicing includes cleaning, lubricating, and adjusting the movement, as well as replacing seals to maintain water resistance.

Ensure the watch is fully wound. Wear it consistently for 8-10 hours, or manually wind it by turning the crown clockwise approximately 40 times if it has hand-winding capability (the 4R36 does). If the issue persists, avoid strong magnetic fields and consider professional servicing.

This indicates the watch is set to the incorrect AM/PM cycle. Pull the crown to the second click (time-setting position) and advance the time by 12 hours. Then, reset the current time.

This indicates moisture has entered the watch, potentially compromising its water resistance. Immediately take the watch to a qualified watchmaker for inspection and drying to prevent further damage to the movement.

Dirt, dust, or dried sweat may be lodged under the bezel. Rinse the watch thoroughly under lukewarm running water while rotating the bezel to help dislodge debris. Dry completely. If it remains stiff, professional cleaning may be required.
