Something deep down in the human psyche compels us to continually push our limits, attempting to go faster, higher and deeper than ever before. And just as humankind has always sought to test the boundaries and achieve the unachievable, watchmakers have attempted to follow suit, creating expertly engineered mechanical marvels that not only keep pace with the parameters of human achievement but have the capability to far exceed them.

In the Oyster Perpetual Deepsea Challenge, best selling clone Rolex watches have created the horological embodiment of that limit-defying spirit. Inspired by the experimental replica watches UK that accompanied filmmaker and explorer James Cameron on his historic 10,908m descent into the Mariana Trench in March 2012, the Deepsea Challenge is an extension of that prototype, making the ground-breaking technology tested on the epic mission available to buy for the first time.

Guaranteed waterproof to a jaw-dropping depth of 11,000m—far deeper than any human could conceive of venturing without a pressurised vessel—the Deepsea Challenge more than lives up to Rolex’s claim that it is “the ultimate AAA Rolex replica watches of the deep”. In fact, so rigorous were the testing criteria that Rolex partnered with marine engineering company Comex to develop a custom-made, ultra-high-pressure tank capable of creating a test pressure environment equivalent to that exerted by water at a depth of 13,750m.

While the pioneering prototype attached to the manipulator arm of Cameron’s 2012 submersible was made from heavy stainless steel to withstand the rigours of the Mariana Trench, the Swiss fake Rolex Deepsea Challenge watches are crafted using grade 5 RLX titanium, resulting in a 30 per cent weight reduction—meaning that, while there’s no denying the heft of this 50mm beast from the deep, it is certainly designed with wearability in mind.

Powered by cheap Rolex fake watches’ calibre 3230 self-winding movement, the timepiece offers a power reserve of about 70 hours, and is accurate to -2/+2 seconds per day.

The 1:1 copy Rolex Deepsea Challenge watches boast the full gamut of Rolex’s famed divers Fwatch expertise, including the patented Ringlock system, a case architecture that enables it to withstand extreme pressure; the helium escape value, which allows surplus gas to be released during the diver’s decompression phase; the Triplock crown, with three sealed zones; and the long-lasting luminescence of a Chromalight display.
