Operating Features

Luminous Hands

The hour and minute hands of your OLEVS watch are equipped with luminous material, allowing for readability in low-light conditions. For optimal luminescence, expose the watch dial to a light source for a period of time before entering a dark environment.

Water Resistance

This watch is water resistant up to 30 meters (100 feet). This means it can withstand splashes or brief immersion in water. It is not suitable for swimming, bathing, diving, or any prolonged water activities. Avoid pressing buttons or pulling the crown while the watch is wet or submerged, as this can compromise the water resistance.

Maintenance

  • Cleaning: Wipe the watch case and strap regularly with a soft, dry cloth to remove dust and dirt. For the leather strap, avoid excessive moisture and harsh chemicals.
  • Storage: When not in use, store your watch in a cool, dry place, away from direct sunlight and extreme temperatures.
  • Battery Replacement: The watch uses one LR44 battery. When the watch stops or the time becomes inaccurate, it may be time to replace the battery. It is recommended to have battery replacement performed by a qualified watch technician to ensure proper sealing and water resistance.
  • Glass Care: The watch features a high-strength mineral glass mirror designed to be wear-resistant and scratch-proof. While durable, avoid unnecessary impacts to prevent damage.
