Thank you very much for viewing. CASIO Baby-G BLX-100-7 watch. The color is white. Mineral glass, 20-bar water resistance. It has a tide graph. The battery has been replaced with a new one. Replaced on 2026.02.05 A tide graph visually represents the ebb and flow of the tide (tidal changes) over time, and is used to predict the times and changes in water level of low and high tides at a specific location. It is essential for fishing, surfing, clamming, etc., to determine when the tide will go out and allow access to the rocks, or when the high tide will provide sufficient water depth at a point. Although slightly faded, it is in very good condition with no damage, cracks, or defects. This is a used item. Please refrain from purchasing if you are sensitive to such things. Immediate purchase is welcome. Thank you for your consideration.
