Rolex: Simple, Robust and Corrosion Resistant.

With a new model, the Oyster Perpetual Explorer 40, measuring 40 mm in diameter, Rolex expands the Explorer line.

Like the Explorer 36, the Explorer 40 stays true to the original design that was introduced in 1953 following the first successful ascent of Mount Everest. The Professional hands and the numbers 3, 6, and 9 are prominently displayed on its black lacquered dial, all of which are inextricably linked to the identity of this clock that personifies the spirit of exploration and tenacity. The Chromalight display of the Explorer 40, which is made of Oystersteel and attached to an Oyster bracelet, provides exceptional visibility in all lighting settings. In the daytime, it stands out for its noticeably bright white colour.

The cutting-edge watchmaking technology of the calibre 3230, which delivers the main functions of hours, minutes, and seconds, is fitted with the Explorer 40. The Oyster Perpetual Explorer 40, like other Rolex watches, has the Superlative Chronometer certification, which guarantees outstanding performance while worn.

The Explorer, which was introduced in 1953, stands for Rolex's intimate connection to adventure. The company started outfitting multiple Himalayan expeditions with Oyster watches in the 1930s. The team that featured Sir Edmund Hillary and Tenzing Norgay, the first climbers to reach the summit of the world at 8,848 metres, was one of these (29,028 feet). This innovative approach exemplified the company's desire to use the actual world as a testing ground for its watches, allowing it to make constant improvements. Rolex's watches evolved as a result of the input they got from the participants in these various excursions, becoming more accurate and durable.

A model of durability and dependability, the Explorer 40's 40 mm Oyster casing is warranted waterproof up to a depth of 100 metres (330 feet). This new model's central casing is made from a whole block of oystersteel. Only Rolex watchmakers are able to access the mechanism through the hermetically sealed case back, which is bordered with delicate fluting. The Twinlock winding crown is screwed down firmly against the casing and equipped with a double waterproofing system. The crystal is composed of almost indestructible sapphire and has an anti-reflective coating. The movement it houses is protected to the highest standard by the waterproof Oyster casing.

The calibre 3230 that powers the Explorer 40 was designed and created solely by Rolex, and it was unveiled in that year. Its self-winding mechanical movement, a distillation of technology, performs admirably in terms of accuracy, power reserve, convenience, and dependability.

The Chronergy escapement, which is patented and has a high energy economy and outstanding reliability, is a feature of the Calibre 3230. This escapement, which is made of nickel-phosphorus, can withstand powerful magnetic fields. A paramagnetic alloy blue Parachrom hairspring made by Rolex is installed in the mechanism. The hairspring provides strong shock resistance and excellent stability in the face of temperature changes. It has a Rolex overcoil, which ensures the calibre's consistency in any setting. The movement's shock resistance is increased by mounting the oscillator on the high-performance Paraflex shock absorbers, which were created by Rolex and are patented. An improved ball bearing has been added to the oscillating weight.

The perpetual rotor of Calibre 3230 serves as the self-winding mechanism. The power reserve of the calibre 3230 extends to almost 70 hours as a result of the barrel design and the higher efficiency of the escapement.
