Seiko 5 Sports SKX GMT Watch - Seiko SSK035K1

GMT stands for Greenwich Mean Time, and in watches, it refers to the ability to track multiple time zones simultaneously. This watch features an independent 24-hour hand (the gold hand) that points to a 24-hour scale on the rotating bezel, allowing you to track a second or even third time zone alongside your local time.

The watch is water resistant to 100 meters (10 ATM). This means it's suitable for showering, swimming, snorkeling, and recreational water sports. It is *not* designed for scuba diving or prolonged underwater activity at significant depths. Always ensure the crown is fully pushed in before any contact with water.

Automatic mechanical watches, including the one in your Seiko 5 Sports SKX GMT, rely on internal gears and springs. They are not as precisely accurate as quartz watches. A typical automatic movement might gain or lose several seconds per day, which is considered normal. Regular wear helps maintain its power reserve and consistent performance.

Hardlex is Seiko's proprietary mineral crystal, which is toughened through a special process. It offers better scratch resistance than standard mineral glass and better shatter resistance than sapphire crystal. While durable, it's still susceptible to scratches and impacts, especially compared to the higher scratch resistance of sapphire.

The 'beads of rice' bracelet, with its intricate links, can accumulate dirt. Use a soft brush (like an old toothbrush) with mild soapy water to gently scrub between the links. Rinse thoroughly with clean, fresh water afterwards to remove all soap residue, and dry completely with a soft cloth to prevent water spots.

The watch is an automatic movement, meaning it self-winds with the motion of your wrist. If you wear it daily for at least 8-10 hours, you generally won't need to manually wind it. However, if the watch has stopped or you haven't worn it for a few days, you can manually wind it by gently shaking it or by rotating the crown about 20-30 times while it's in the pushed-in (neutral) position.

Lumi Brite is Seiko's original luminous paint. It absorbs light energy from sunlight or artificial light in a short time and stores it to emit light in the dark. It is entirely free of radioactive substances, ensuring safety, and provides long-lasting, bright luminescence for excellent readability in low-light conditions.

The Seiko 5 Sports SKX GMT is an automatic watch. It needs to be worn regularly or manually wound. If it has stopped, gently shake it side-to-side for about 30 seconds, or manually wind the crown 20-30 times while it's in the pushed-in position. If worn daily, ensure it's on your wrist for at least 8-10 hours. If the issue persists after winding/wearing, it may require professional servicing.

This indicates that the watch's internal AM/PM setting is incorrect. Pull the crown to the second click position (stopping the seconds hand). Advance the hour hand by 12 hours. Once corrected, push the crown back in. Remember to avoid setting the date/day between 9 PM and 4 AM to prevent damaging the movement.

The gold GMT hand moves once every 24 hours and is directly tied to the main hour hand. To set it, first set your local time. Then, pull the crown out to the second position and rotate the main hour hand until the GMT hand points to the correct 24-hour time of your desired second time zone. Once set, you can rotate the external bi-directional bezel to quickly reference a third time zone or adjust your primary GMT reference.

Immediately take the watch to a professional watchmaker. This indicates a breach in the water resistance seals. Do not attempt to dry it yourself, as moisture can quickly damage the movement. Avoid further water exposure until serviced.
