Setup
Setting Time and Date
- Pull out the crown: Gently pull the crown located on the side of the watch to the second click position.
- Set the time: Rotate the crown to move the hour and minute hands to the desired time. Ensure AM/PM is correctly set if your watch has a 24-hour indicator or if setting the date.
- Set the date: Push the crown in one click to the first click position. Rotate the crown to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement.
- Push in the crown: Once the time and date are set, push the crown back into its normal position to start the watch.
Charging the Solar Movement
Your Orient Mako Solar watch is powered by light. To ensure optimal performance, expose the watch dial to light regularly. The watch will charge from both natural and artificial light sources. For initial charging or after prolonged storage in darkness, place the watch in direct sunlight for several hours. Avoid extreme temperatures during charging.
Operating
Basic Timekeeping
Once set, your watch will maintain accurate time using its solar-powered quartz movement. The second hand will move in one-second intervals. If the watch stops or the second hand moves erratically, it may require charging.
Using the Chronograph
The Orient Mako Solar 20th Anniversary watch features a chronograph function, indicated by the sub-dials on the main face. The specific operation of the chronograph (start, stop, reset) is typically controlled by the pushers located above and below the crown. Refer to the detailed movement guide for precise instructions on using the chronograph sub-dials for measuring elapsed time.
Maintenance
Cleaning
To maintain the appearance of your watch, wipe the case and bracelet regularly with a soft, dry cloth. For stainless steel, a slightly damp cloth can be used, followed by drying. Avoid using harsh chemicals or abrasive materials.
Water Resistance
Your watch has a water resistance of 200 meters. This rating means it is suitable for showering, swimming, and snorkeling. However, it is not designed for scuba diving. Always ensure the crown is fully pushed in before exposing the watch to water. Avoid operating the crown or pushers while the watch is wet or submerged.
Solar Cell Care
To ensure the longevity of your solar cell, avoid prolonged storage in complete darkness. If the watch is stored in darkness for an extended period, it may enter a power-saving mode or stop completely. Expose it to light to reactivate and recharge it.

Troubleshooting
- Watch not running: Ensure the watch has been sufficiently charged by exposing it to light. If it still doesn't run, contact customer support.
- Date not changing: Check if the time is set correctly for AM/PM. If the date is stuck, try manually advancing it past 3 AM.
- Water ingress: If moisture appears inside the watch, immediately take it to an authorized service center.
