Setup and Time Setting
Your Oulm 3595 watch requires individual time setting for each of its three dials. Each dial operates independently.
- Identify the Crowns: Each of the three dials (one large, two small) has a corresponding crown located on the side of the watch case.
- Pull Out the Crown: Gently pull out the crown associated with the dial you wish to set. You should feel a slight click.
- Set the Time: Rotate the crown clockwise or counter-clockwise to adjust the hour and minute hands to the desired time.
- Push In the Crown: Once the time is set, push the crown back into its original position. This locks the time and starts the movement.
- Repeat for All Dials: Follow these steps for each of the three dials to set your desired time zones.
Battery Information:
The Oulm 3595 watch requires 3 LR44 batteries, one for each quartz movement. When the watch stops or runs inaccurately, it is likely time to replace the batteries. Battery replacement should ideally be performed by a qualified watch technician to avoid damage to the watch's internal components.
Operating Instructions
Once the time is set on all three dials, your Oulm 3595 watch will continuously display the three chosen time zones. There are no additional operating functions beyond time display.
- The main dial is typically used for your local time.
- The two smaller sub-dials can be set to display times in other cities or regions, useful for travel or international communication.
Maintenance and Care
Cleaning:
To maintain the appearance of your watch, wipe the case and crystal with a soft, dry cloth. For the leather strap, avoid excessive moisture and harsh chemicals. If the strap becomes dirty, gently wipe it with a slightly damp cloth and allow it to air dry completely.
Water Resistance:
IMPORTANT: This watch is NOT water resistant.
Avoid all contact with water, including rain, splashes, showering, swimming, or any other water-related activities. Exposure to water can cause severe damage to the internal quartz movements and is not covered under any potential warranty.
Storage:
When not in use, store your watch in a cool, dry place away from direct sunlight and extreme temperatures. Avoid exposing the watch to strong magnetic fields, which can affect the accuracy of the quartz movements.
Troubleshooting
- Watch is not running or running inaccurately:
This is typically an indication of a depleted battery. As the watch uses three separate movements, one or more dials might stop while others continue. Replace the 3 LR44 batteries. If the issue persists after battery replacement, consult a professional watch repair service.
- Hands are not moving after setting:
Ensure the crown for that specific dial is fully pushed back into its normal operating position. If the crown is pulled out, the movement will remain stopped.
- Condensation under the crystal:
This indicates moisture has entered the watch case. As the watch is not water resistant, this can cause significant damage. Immediately seek professional watch repair to prevent further corrosion.
