TWINLOCK WINDING CROWN
The Twinlock system guarantees that the screw-down winding crown is perfectly water-resistant, thanks to two sealed zones, one inside the tube, the other inside the crown. This principle is used on all the watches in the Oyster collection that are guaranteed waterproof to 100 meters (330 feet).
The Oyster Case, Symbol Of Waterproofness
The Explorer’s Oyster case, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness. Its characteristically shaped middle case is crafted from a solid block of particularly corrosion-resistant Oystersteel. The fluted case back is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. Fitted with the Twinlock double waterproofness system, the winding crown screws down securely against the case. The crystal is made of virtually scratchproof sapphire. The waterproof Oyster case provides optimum protection for the Explorer’s high-precision movement.

Solid-Link Bracelet And Safety Clasp
The Explorer is fitted on a solid-link Oyster bracelet in Oystersteel with an Oysterlock safety clasp that prevents accidental opening. It features the ingenious Rolex-patented Easylink rapid extension system that allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance.
To increase the resistance of its movements to shocks – especially if the watch is dropped – Rolex developed Paraflex, a highly efficient shock absorber designed to protect sensitive components of the movement, notably the staff of the balance wheel. Paraflex shock absorbers increase shock resistance by up to 50 per cent.
Perpetual Calibre 3132
The Explorer is equipped with calibre 3132, a self-winding mechanical movement entirely developed and manufactured by Rolex. Its architecture, manufacturing quality and innovative features make it singularly precise and reliable. The oscillator, the true heart of the watch, has a blue Parachrom hairspring patented and manufactured by Rolex in an exclusive alloy. Insensitive to magnetic fields, the Parachrom hairspring offers great stability in the face of temperature variations and remains up to 10 times more precise than a traditional hairspring in case of shocks.
It is equipped with a Rolex overcoil, ensuring its regularity in any position. The oscillator is held firmly in place by a height-adjustable traversing bridge and is fitted between high performance Paraflex shock absorbers, developed and patented by Rolex, that provide 50 per cent greater resistance to shocks. Calibre 3132 is equipped with a self-winding module via a Perpetual rotor and offers a power reserve of approximately 48 hours.
Superlative Chronometer Certification
The Explorer is covered by the Superlative Chronometer certification redefined by Rolex in 2015. This exclusive designation testifies that the watch has successfully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria, which exceed watchmaking norms and standards. The certification applies to the fully assembled watch, after casing the movement, guaranteeing superlative performance on the wrist in terms of precision, power reserve, waterproofness and self-winding. The precision of a Rolex Superlative Chronometer after casing is of the order of −2/+2 seconds per day, or more than twice that required of an official chronometer. The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.
