People talk about space as a new and exciting world, one that is yet to be fully explored. It’s true: we don’t know much about what’s happening beyond our moon, but the same can be said about the depths of our oceans. Just over 70% of the Earth is covered in water, and it’s almost seven miles deep in places. Down there, it’s so dark you can’t see an inch in front of you; there are deep-sea animal species that will probably never be known to man. Space has nothing on the dark and hidden nooks of the ocean. It’s the fascination with this unknown world, and a desire to equip us when exploring it, that drives Rolex to develop watches able to tell time when deep-sea diving at record-breaking depths. Cue the new Oyster Perpetual Rolex Deepsea watch. Water-resistant down to 3,900 metres, it is state of the art technology, whether for personal or professional use. Made out of oyster steel, the watch features a patented Ringlock system composed of three elements: a domed 5.5mm-thick sapphire crystal, a high-performance nitrogen-alloyed stainless steel ring, positioned inside the middle case of the watch, and a case back made out of grade-5 titanium. The Triplock winding crown, equipped with three seals, screws down securely against the case, completing the waterproofness system and guaranteeing watertight security akin to a submarine’s hatch.
