Seiko 5 Sports Retro - Black Dial - Stainless Steel Bracelet

If you wear the watch daily (8-10 hours), the automatic movement will generally keep it sufficiently wound. If you don't wear it for more than 40 hours, it will stop, and you'll need to manually wind it about 20-30 times before setting the time to restart it.

Yes, with 100 meters of water resistance, this watch is suitable for recreational swimming, snorkeling, and showering. Always ensure the crown is fully pushed in before any water exposure. Avoid exposing it to hot water or steam for prolonged periods, as this can affect the seals.

Hardlex is Seiko's proprietary hardened mineral crystal. It offers a good balance of scratch resistance and superior impact resistance compared to standard mineral glass. While more durable than regular glass, it is not as scratch-resistant as sapphire crystal.

The Caliber 4R36 movement is a robust and reliable workhorse. Officially, Seiko movements can vary, but typically expect an accuracy of around -15 to +25 seconds per day. Factors such as how active you are, the watch's position when resting, and temperature can influence its daily performance.

Yes, the hands and hour markers are treated with Seiko's Lumibrite, a highly effective luminous material. After exposure to light, it glows brightly in the dark, allowing for easy time reading in low-light conditions.

Absolutely. The 38mm case diameter is often considered an ideal 'midi' size, making it very versatile. It typically wears comfortably on smaller wrists without feeling too large, while still having a noticeable presence.

The Caliber 4R36 is an automatic movement, meaning it's powered by your wrist's motion. If unworn for more than 40 hours, it will stop. Try manually winding it about 30 times using the crown (with the crown pushed in) or wear it consistently for several hours. If it continues to stop or lose significant time, it may require servicing due to magnetism or a mechanical issue.

First, ensure the time is set correctly, especially the AM/PM. The day/date changes automatically around midnight. Avoid adjusting the day/date between 9:00 PM and 3:00 AM, as this is when the internal mechanism is engaged for the changeover and forcing it can cause damage. If you need to set the date within this window, first move the time outside of it (e.g., to 6:00 AM), set the date, then reset the time.

This indicates that moisture has entered the watch, compromising its water resistance. Immediately take the watch to a professional watchmaker for inspection and repair. Delaying this can lead to corrosion of the internal components.

Mechanical watches inherently have some variation in accuracy. The 4R36 movement is typically accurate within a range of about -15 to +25 seconds per day under normal conditions. Factors like position, temperature, and activity level can affect this. If the deviation is significantly outside this range, it might be magnetized or require regulation/servicing by a watchmaker.
