Even though most watches have water-resistant features, they have different resistant levels. For instance, 30M, 50M, 100M, and 200M are water resistant. The 30M water resistant is designed to withstand daily usage. So you can consider a 100M water-resistant rating where it can be used for surfing, snorkeling, kayaking, and swimming. In addition, if you prefer the highest resistance level, a 200M can be found in a diving watch that can be used for freediving and scuba diving.
