Casio Pro Trek (Fishing Gear) I have confirmed that it was working until the summer of 2025, but it seems the battery has died after being left unused. The battery has not been replaced, and it is unknown if it currently works, so it is being sold as junk. No claims or returns accepted. Purchased about 20 years ago, and used for mountain climbing and skiing. This is a decluttering sale. The following is a product description from Mercari AI: - Brand: CASIO - Model Name: Fishing Gear - Water Resistance: Up to 100m depth - Back Engraving: Fishing Gear - Light Function: Auto light switch Thank you for viewing.
