20 ATM (Atmospheres) or 200 meters means the watch is suitable for recreational scuba diving and high-board diving. It can withstand significant water pressure.

Yes, with 20 ATM water resistance, the watch is safe to wear while swimming and showering. However, it's recommended to rinse with fresh water and dry thoroughly after exposure to salt or chlorinated water.

Most solar watches do not have a specific indicator. You can infer charging by the watch running consistently. If it stops, it likely needs more light exposure.
