Features

Eco-Drive (solar powered) watch

The watch operates by converting sunlight and other light into electrical energy. Once the rechargeable cell is fully charged, the watch will function for approximately 8 months.

Insufficient charge warning

If the power becomes very low, the second hand advances at 2-second intervals, indicating that charging is necessary. When the second hand starts to advance at 2-second intervals, expose the watch to light until it is fully charged.

If the watch is not exposed to light within approximately 5 days after the insufficient charge warning starts, the watch will stop.

Quick start function

When the stopped watch is exposed to light, it starts operating again.

After quick start, expose the watch to light until it is fully charged. Set the correct time before using the watch.

Notes Before Use

Notes before use - Protective stickers

Prior to the watch being shipped from the manufacturing plant, its glass, case, metal band, and metal parts of the clasp are covered with stickers to protect them from getting fingerprints or scratches during transit from the plant to the store. If the watch is worn without first removing these stickers, perspiration or moisture may enter the gaps between the protective stickers and the parts, which may result in a skin rash and/or corrosion of the metal parts.

For this reason, please be sure to peel off the stickers before wearing the watch.
