Setup and Initial Use
Before wearing your Oulm 3595 watch, please follow these steps for initial setup.
1. Setting the Time
The Oulm 3595 watch features three independent movements, each controlled by its own crown. Identify the crowns corresponding to each sub-dial.
- Main Dial (Center): Pull out the crown located on the right side of the watch case to the first position. Rotate the crown clockwise or counter-clockwise to set the desired time. Once set, push the crown back in to secure the time.
- Upper Left Sub-dial: This sub-dial typically displays a second time zone. Pull out its dedicated crown (usually on the upper left side of the case) and rotate to set the time. Push the crown back in when finished.
- Lower Left Sub-dial: Similar to the upper left, this sub-dial can be used for a third time zone. Pull out its dedicated crown (usually on the lower left side of the case) and rotate to set the time. Push the crown back in when finished.
2. Adjusting the Strap
The watch comes with a comfortable leather strap with a buckle closure. To adjust the fit:
- Insert the pin of the buckle into one of the holes on the strap that provides a snug yet comfortable fit around your wrist.
- Ensure the watch is not too tight, which could restrict circulation, nor too loose, which could cause it to slide excessively.

Maintenance and Care
Proper care will extend the life and maintain the appearance of your Oulm 3595 watch.
- Cleaning: Wipe the watch case and crystal with a soft, dry cloth. For the leather strap, use a slightly damp cloth if necessary, and allow it to air dry completely. Avoid harsh chemicals or abrasive materials.
- Water Resistance: This watch is not specified as water-resistant. Avoid exposure to water, including showering, swimming, or heavy rain, to prevent damage to the internal components.
- Temperature: Avoid exposing the watch to extreme temperatures, both hot and cold, as this can affect the accuracy of the movement and the integrity of the materials.
- Battery Replacement: The watch uses 3 Lithium Metal batteries. When the watch stops keeping accurate time or stops completely, it is likely time to replace the batteries. It is recommended to have battery replacement performed by a qualified watch technician to avoid damaging the watch.
- Strap Care: Leather straps can show wear over time. Avoid prolonged exposure to direct sunlight or moisture, which can cause the leather to crack or fade.
