The Engineer Hydrocarbon Deep QUEST is a response tool for all divers who are willing to reach the deepest depths. It features BALLs patented automatic helium release valve directly integrated into the crown. The ultra-tough monobloc titanium case reduces potential interfaces and thus diminishes effects of water pressure. Titanium not only offers extreme corrosion resistance in water, but also outstanding everyday durability and strength. The Deep QUEST is water resistant up to 1, 000 meters and is meant to reach dark environments. Strengthening the crown seals has contributed to avoid any entry of water when it is maintained in the screwed-in position. The rotating diving bezel has been designed to be easily gripped even with gloves on and its unidirectional rotation is an additional source of safety. The dial and the hands feature wider Hgas tubes in green color, one of the brightest tones that glows in the dark. This astonishing state-of-the-art Swiss technology - the iconic sign
