A watch marked as water resistant with no specific depth can handle light exposure to water, such as accidental splashes. This type of watch is not meant to be submerged in water. If the watch has a measured depth on the dial, then it can withstand exposure to water up till the depth indicated on the watch. Some watches, specifically divers, have a screw-in crown that seals the watch from water. Please make sure this type of watch is properly sealed in order to prevent water damage.
0-30 Meters- Can withstand splashing, rain, and accidental water exposure. Should not be used to swim. 50 Meters- Can be worn in a shower or while swimming in shallow waters. 100 Meters- Can be used for Snorkeling and Swimming. We recommend 100 Meters as a minimum for swimming. 200 Meters- Skin Diving. If it is a Diver's 200, then it meets ISO standards for Scuba Diving. Please be aware that if the band is made out of canvas or leather, it may sustain water damage even if the watch case is resistant. For swimming, a stainless steel, titanium, or rubber band is a more resilient choice.
