did u see the Water in the watch? my friend swam with this casual fashion watch in his condo pool!
according to a Watch Guide, a watch that's marked 10 atm or 100m up is safe for swimming. if your watch has no such indication then Don't ever swim with it. whether it's a casual or hi-end brand, Don't take risk.
recall a super rich china man murdered his brand new Patek by bringing it to sauna!
