Divers need timepieces that are reliable and readable in even the toughest of conditions. The Ball Engineer Master II Diver timepiece is designed to perform impeccably. The bezel, numerals and hands are illuminated through the use of 53 self-powered micro gas tubes that glow 100 times brighter than regular luminous paint. The timepiece is equipped with Swiss-made ETA 2836-2 automatic calibre that has 25 bearing jewels. The inner rotating bezel is operated through a screw-down crown. This watch is protected from water penetration, shock and magnetic influences. Additional functionalities include a day and date display, elapsed time bezel, screwed-in crown, factory engraved case back and convex sapphire crystal glass with anti-reflective coating.
