The Orient Sports Mako 40 mm is a robust timepiece designed for sports and outdoor enthusiasts. It features a precise mechanical movement (Calibre F6722) with both manual and automatic winding capabilities, a durable sapphire crystal, and a high level of water resistance suitable for swimming and shallow diving.
Setup and Initial Operation
1. Winding the Watch
Your Orient Sports Mako watch is powered by a mechanical movement that can be wound manually or automatically through wrist motion.
- Manual Winding: To initiate power or if the watch has stopped, unscrew the crown (if applicable) and turn it clockwise approximately 30-40 times. This will build up a power reserve.
- Automatic Winding: The watch will automatically wind itself through the natural motion of your wrist while wearing it. For optimal performance, wear the watch for at least 8-10 hours daily.
2. Setting the Time and Date
- Unscrew the Crown: Gently unscrew the crown counter-clockwise until it is free from the case.
- Pull to Position 1 (Date Setting): Pull the crown out to the first click. Turn the crown clockwise or counter-clockwise to set the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement.
- Pull to Position 2 (Time Setting): Pull the crown out to the second click. The second hand will stop. Turn the crown to set the hour and minute hands. To ensure accuracy, set the time a few minutes ahead and then turn the crown counter-clockwise to move the hands back to the correct time.
- Push and Screw Down the Crown: Once the time and date are set, push the crown back in fully and screw it down clockwise tightly against the case. This ensures water resistance.
3. Adjusting the Bracelet
The stainless steel bracelet can be adjusted by adding or removing links. This procedure typically requires specialized tools and is best performed by a qualified watchmaker or jeweler to prevent damage to the bracelet or watch.

Operating Guidelines
Water Resistance
Your Orient Sports Mako watch is water resistant to 20 atmospheres (200 meters / 660 feet). This rating makes it suitable for swimming, snorkeling, and non-deep diving activities. Important:
- Ensure the crown is always fully screwed down before any contact with water.
- Do not operate the crown or pushers (if any) while the watch is wet or submerged.
- Avoid exposing the watch to hot water, steam, or sudden temperature changes, as this can compromise the seals.
- Water resistance is not a permanent condition and may be affected by aging gaskets or accidental shocks to the crown. It is recommended to have the water resistance checked periodically by an authorized service center.
Maintenance and Care
- Cleaning: Wipe the watch case and bracelet regularly with a soft, dry cloth. For stubborn dirt, especially on the bracelet, use a soft brush with mild soapy water, then rinse thoroughly with clean water and dry completely. Ensure the crown is screwed down before cleaning with water.
- Avoid Chemicals: Do not expose your watch to solvents, detergents, perfumes, or cosmetics, as these can damage the gaskets, case, or bracelet.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures (above 60°C / 140°F or below 0°C / 32°F) or sudden temperature changes.
- Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, mobile phones, airport security scanners), as magnetism can affect the accuracy of the mechanical movement.
- Shocks: While durable, avoid dropping the watch or subjecting it to severe impacts.
- Service: Mechanical watches require periodic servicing (typically every 3-5 years) to ensure optimal performance and longevity. This includes cleaning, lubrication, and checking of seals. Contact an authorized Orient service center for professional service.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch has stopped or runs intermittently. | Insufficient power reserve. | Manually wind the watch by turning the crown clockwise 30-40 times. Wear the watch regularly to allow automatic winding. |
| Watch is running too fast or too slow. | Exposure to strong magnetic fields; need for regulation; internal issue. | Keep away from magnetic sources. If problem persists, seek professional service for demagnetization or regulation. |
| Date changes at noon instead of midnight. | AM/PM setting is incorrect. | Advance the time by 12 hours. |
| Condensation under the crystal. | Compromised water resistance. | Immediately take the watch to an authorized service center. Do not attempt to dry it yourself. |
