The Rolex Datejust 126300-0017 showcases the brand's commitment to excellence through its Oystersteel case, a proprietary 904L steel known for exceptional corrosion resistance and durability, often used in high-tech and aerospace industries. This case, part of Rolex's groundbreaking 1926 Oyster design - the first waterproof wristwatch case - set new durability standards with a bezel, case back, and crown protecting intricate inner mechanisms. The lugs crafted from refined alloys connect the bracelet and watch, adding elegance through polished or satin finishes. Enhancing functionality, the Cyclops lens introduced in 1953 magnifies the date at 3 o'clock on scratch-resistant sapphire crystal with an anti-reflective coating, ensuring easy readability at a glance.

The Oyster bracelet exemplifies Rolex's blend of form and function, offering robust durability and comfort with an elegant design. Equipped with the exclusive Oysterclasp and the patented Easylink comfort extension link introduced in 1996, this innovative system allows wearers to adjust the bracelet length by approximately 5 mm with a simple movement, enhancing comfort in any situation.

The Oysterclasp, protected by a folding cover, opens effortlessly with a single motion, combining secure closure with easy opening for daily use. It delivers a unique, reassuring feel with a slight resistance followed by a sharp, confident click, symbolising its reliability. The subtle extension provided by Easylink transforms a well-fitted bracelet into a perfectly fitted one, showcasing Rolex's relentless pursuit of wearable perfection through even the most minor adjustments, ensuring continued comfort in everyday life.

The bright blue dial showcases a sunray finish. This watchmaking technique creates delicate light reflections on many dials in the Oyster Perpetual collection. Expert brushing techniques form grooves radiating from the dial's centre, allowing light to diffuse along each engraving and produce a subtle glow that shifts with the wrist's position. After completing the sunray finish, Rolex applies the blue colour using Physical Vapour Deposition or electroplating, then adds a light coat of varnish for the final touch.

Roman numerals are a popular choice for hour markers, and they are known for their elegance and classic appeal. Often featured on formal and luxury watches, they bring a touch of sophistication and tradition, making them a favoured option for high-end mechanical timepieces.

Rolex equips the Datejust 126300-0017 with the Calibre 3235, a self-winding mechanical movement known for its precision and durability. It has a 70-hour power reserve and uses the Chronergy escapement, which improves efficiency and resists magnetic interference. It includes a blue Parachrom hairspring for stability against shocks and temperature changes and Paraflex shock absorbers for extra durability. The Calibre 3235 highlights Rolex's dedication to high performance and reliability.

The Rolex Calibre 3235

The Rolex Calibre 3235 movement is a cutting-edge, self-winding mechanical movement that exemplifies Rolex's commitment to innovation and precision. This movement, developed entirely in-house, boasts a 70-hour power reserve, allowing it to maintain accuracy over extended periods without needing to be wound.

This innovative design improves the movement's efficiency by 15%, contributing to its impressive accuracy of -2/+2 seconds per day, surpassing COSC chronometer standards.

Additionally, the calibre 3235 is fitted with Rolex's blue Parachrom hairspring, which is highly shock-resistant and unaffected by temperature variations, ensuring stable performance in all conditions. The movement is also equipped with Paraflex shock absorbers for enhanced durability, making it exceptionally robust and reliable.
