This watch features a bi-colour 24-hour bezel coated in Hardlex for enhanced durability. The GMT hand improves practicality, visibility, and legibility, making it ideal for international timekeeping. The 'beads of rice' bracelet is a nod to the SKX heritage, with a five-piece link design forming small X-shaped patterns. Designed for practical international timekeeping, the GMT hand, high visibility hour markers, and clear 24-hour bezel allow for easy multi-time zone calculations at a glance. The hands and indices are coated in Lumi Brite, a fluorescent luminous paint that absorbs light energy, glowing brighter and longer in low light conditions. Seiko 5 Sports has a legacy of over fifty years, known for reliability, durability, performance, and value. The '5' signifies the original five key features: Automatic movement, Day-date display, Water Resistance, Recessed crown, and Durable case and bracelet. Key specifications include a 4R34 Automatic movement with manual winding and a 41-hour power reserve. The dial is blue, and it features LumiBrite on the hands and indexes. The case is stainless steel, paired with a stainless steel bracelet and a three-fold clasp with a secure lock. The case measures 42.5mm in diameter, 13.56mm in thickness, and 46.0mm in length, with a lug width of 22.0mm. It has a water resistance of 10 bar and a Hardlex crystal with magnification. Additional features include a see-through case back, a rotating bezel, and a stop seconds hand function.

FAQs
What does '10 bar water resistance' mean for this watch?
10 bar (or 100 meters) water resistance means the watch is suitable for everyday use, including splashes, rain, showering, and swimming. It is not designed for high-impact water sports, diving, or prolonged submersion at depths.
How do I care for the Hardlex crystal?
While durable, Hardlex can scratch. Avoid direct contact with abrasive surfaces. Clean with a soft, damp cloth. If scratches occur, professional polishing might be an option, but prevention is best.
What is the power reserve of the 4R34 movement?
The Seiko 4R34 automatic movement has a power reserve of approximately 41 hours when fully wound. If unworn for longer than this, it will stop and need to be reset and wound.
Can I change the bracelet on this watch?
Yes, the watch has a lug width of 22.0mm, which is a common size. You can replace the 'beads of rice' bracelet with other 22mm straps (leather, nylon, rubber, etc.) to customize its look.
How accurate is the automatic movement?
Automatic movements typically have a stated accuracy range. While not as precise as quartz, the Seiko 4R34 is known for its robust and reliable performance within standard mechanical watch tolerances. *Info needed: Specific accuracy range from manufacturer.*
What is LumiBrite and how does it work?
LumiBrite is a non-radioactive, phosphorescent luminous paint developed by Seiko. It absorbs light energy from sunlight or artificial light and stores it, emitting light in the dark. The brightness and duration of the glow depend on the amount and intensity of light it has absorbed.
Troubleshooting
Watch stops or loses time frequently.
Ensure the watch is fully wound. For automatic movements, this means wearing it regularly (8-10 hours a day) or manually winding it using the crown if it has been stationary for more than 41 hours.
LumiBrite is not glowing brightly.
LumiBrite requires exposure to light to charge. Expose the dial to bright natural or artificial light for a few minutes. The glow duration and intensity depend on the charge time and light source.
GMT hand is not showing the correct time zone.
Re-set the GMT hand according to the instructions in the 'Setting the Time and GMT Hand' section. Ensure you are setting it to the desired second time zone's 24-hour format and not mistaking it for the main hour hand.

Setup, Compatibility & Care
Setting the Time and GMT Hand
Unscrew the crown (if applicable, though typically for higher water resistance ratings) and pull it out to the first position. For the 4R34, the crown usually pulls out directly.
First Click (Time & Date Adjustment): Pull the crown out to the first click. Rotate the crown counter-clockwise (or clockwise, consult the manual for exact direction) to advance the GMT hand independently. Rotate the crown clockwise (or counter-clockwise) to set the date (if present, though not explicitly stated for this model, standard GMT functionality often allows for this). *Info needed: Confirm exact crown positions and rotation for GMT/date setting.*.
Second Click (Main Time Adjustment): Pull the crown out to the second click. This will stop the seconds hand (stop seconds hand function). Rotate the crown to set the main hour and minute hands to the desired local time. Push the crown back in to start the watch.
Using the Bezel: Rotate the bi-color 24-hour bezel to align with the GMT hand for tracking a third time zone, as described in the Performance section.
Compatibility
With a case diameter of 42.5mm and a lug-to-lug length of 46.0mm, this watch is well-suited for a variety of wrist sizes. The 22.0mm lug width allows for easy strap changes if you wish to personalize the watch further.
Care and Maintenance
Cleaning: Regularly wipe the watch case, crystal, and bracelet with a soft, dry cloth to remove dirt and oils. For a deeper clean, use a mild soap and water solution with a soft brush, ensuring the crown is pushed in. Rinse thoroughly and dry completely.
Water Resistance: The watch is rated for 10 bar (100 meters) of water resistance. This means it is suitable for showering, swimming, and snorkeling. However, it is not recommended for scuba diving or high-impact water sports.
Winding: If the watch stops due to insufficient power reserve, you can manually wind it by turning the crown clockwise in its pushed-in position (or first position for some movements) about 40 times. The most effective way to keep it wound is by wearing it regularly.
Avoid Extreme Conditions: Protect the watch from extreme temperatures, strong magnetic fields, and harsh chemicals.
