2. Setup and Time Setting
Your OULM HP9415 watch is equipped with two separate quartz movements, each controlled by its own crown. This allows for independent time setting for two different time zones.
2.1 Setting the Main Time Zone (Large Dial)
- Locate the crown on the right side of the watch case, adjacent to the large time dial.
- Gently pull the crown outwards until you feel a click. The watch hands will stop moving.
- Rotate the crown clockwise or counter-clockwise to adjust the hour and minute hands to the desired time.
- Once the time is set, push the crown back into its original position. The watch hands will resume movement.
2.2 Setting the Second Time Zone (Smaller Dial)
- Locate the crown on the left side of the watch case, adjacent to the smaller time dial.
- Gently pull the crown outwards until you feel a click. The watch hands will stop moving.
- Rotate the crown clockwise or counter-clockwise to adjust the hour and minute hands to the desired second time zone.
- Once the time is set, push the crown back into its original position. The watch hands will resume movement.

3. Operating Your Watch
Your OULM HP9415 watch is designed for straightforward operation once the time is set.
3.1 Time Display
- The large dial displays the primary time zone.
- The smaller dial displays the secondary time zone.
3.2 Decorative Dials
As mentioned, the small dials resembling a compass and a thermometer are purely for aesthetic purposes and do not provide functional readings. They are integrated into the watch's design to enhance its unique military-inspired appearance.
4. Care and Maintenance
Proper care will help maintain the appearance and functionality of your OULM HP9415 watch.
4.1 Cleaning
- Wipe the watch case and crystal with a soft, dry cloth to remove dust and fingerprints.
- For the leather band, avoid excessive moisture. If it gets wet, allow it to air dry naturally, away from direct heat.
4.2 Water Resistance
This watch is water resistant. However, it is not suitable for swimming, showering, or diving. Avoid direct contact with water to prevent damage to the internal components and the leather band. Water resistance ratings typically protect against splashes and brief exposure to rain.
4.3 Battery Replacement
The watch is powered by a quartz movement, which requires a battery. When the watch stops running or the time becomes inconsistent, it is likely time for a battery replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and prevent damage to the movement.
4.4 Storage
When not in use, store your watch in a cool, dry place, away from direct sunlight, extreme temperatures, and strong magnetic fields, which can affect the accuracy of the quartz movement.

5. Troubleshooting
If you encounter any issues with your watch, please refer to the following common troubleshooting steps:
- Watch Not Running: Ensure that both crowns are fully pushed in. If the watch still does not run, the battery may need replacement.
- Incorrect Time: Follow the time setting instructions in Section 2 to reset the time for both dials.
- Condensation Inside Crystal: This may indicate a breach in the watch's water resistance. It is recommended to seek professional service immediately to prevent further damage to the movement.
