Seiko 5 Sports - Green Dial

To set the time, pull the crown out to the second click and rotate. For day/date, pull the crown out to the first click; rotate clockwise for the date and counter-clockwise for the day. Push the crown back in completely after setting.

An automatic movement means the watch is powered by the natural motion of your wrist. It doesn't require a battery but needs to be worn regularly or manually wound to maintain its power reserve. The Calibre 4R36 has a power reserve of approximately 41 hours.

Yes, with 100 meters (10 ATM) of water resistance, your watch is suitable for swimming, snorkeling, and showering. However, it is not designed for diving with tanks or high-impact water sports. Always ensure the crown is fully pushed in before any water exposure.

Hardlex is Seiko's proprietary hardened mineral crystal. It offers better scratch resistance than standard mineral glass and is more shatter-resistant than sapphire. While durable for everyday use, it can still be scratched by harder materials like concrete or granite.

It is generally recommended to have an automatic mechanical watch serviced every 3 to 5 years. This helps to clean, lubricate, and adjust the movement, ensuring optimal performance and extending its lifespan.

Regularly wipe the case and bracelet with a soft, damp cloth. For deeper cleaning, you can use a mild soap and water solution, ensuring the crown is fully closed. Rinse thoroughly with fresh water afterwards, especially after saltwater exposure.

The unidirectional rotating bezel is primarily used to measure elapsed time. You align the bezel's triangle marker with the minute hand, and as minutes pass, you can read the elapsed time from the bezel scale. It rotates only counter-clockwise to prevent accidental shortening of timed intervals.

Ensure the watch is fully wound. Wear it for 8-10 hours or manually wind it by turning the crown clockwise for 60 turns with the crown in the normal position. Automatic watches need movement to maintain power.

First, check if the AM/PM is correctly set. The date change typically occurs around midnight. If it's changing at noon, you need to advance the time by 12 hours. Avoid setting the day/date manually between 9 PM and 3 AM to prevent damage to the movement.

This indicates a breach in water resistance. Take the watch to a qualified watchmaker immediately to prevent further damage to the movement. Avoid temperature extremes and ensure the crown is always pushed in when exposed to water.

Automatic watches may have slight variations in accuracy. If the deviation is significant (e.g., more than +/- 20-30 seconds per day), it might need regulation by a professional watchmaker. Strong magnetic fields can also affect accuracy; keep the watch away from magnets.
