User Tips
- Enhancing Luminous Display: To quickly achieve a brighter luminous effect, expose the watch dial to a strong light source (like a flashlight or the watch's own EL light) for approximately 40 seconds. This charges the luminous material.
- Strap Adjustment: If you have a steel strap, it may require professional adjustment to fit your wrist perfectly.
