The crown of the watch screws down securely, and the sapphire crystal is nearly 4 mm thick, making it ideal for professional divers. The case includes a helium valve, protecting the watch from damage from pressure changes while a diver is ascending or descending in a diving bell. The large hands and prominent hour markers are all coated with Super-LumiNova, which glows light blue in the dark, making them more legible under water.
