How do I adjust the strap size?
The resin strap uses pins and can be resized by removing links. Use a pin remover tool or a small screwdriver to push the pins out. Alternatively, visit a jeweler for quick adjustment.

Yes, it has an electroluminescent backlight. Press the LIGHT button to illuminate the display for a few seconds. The light is especially useful in low-light conditions.
