The super luminous hands and hour markers make the watch easy to read time even in low light conditions (e.g. night, swimming, diving). A super luminous bezel dot above the 12 o'clock marker make it easier to see the time underwater, especially when you are a bit disoriented underwater. Multifunctional: The 4 o'clock screw-in crown doesn't dig into the back of your hand and keep water from entering your timepiece. Note: It's very important to make sure the crown is screwed down well before entering the water with your watch. If the crown is loose, water can enter the watch and damage the internal parts. The screw-in case back is sealed by a rubber seal to keep out liquids and prevent moisture from getting inside the watch case and movement.
