Rolex Day-Date 40mm Black 228348RBR

Onyx Dial

A True Expression of Art and Innovation

Every Rolex dial is crafted as a refined work of art, where colour, light, texture, and design elements combine to define the watch’s unique identity. The onyx dial reflects this dedication to detail, delivering a deep, elegant surface that enhances the timepiece’s character.

Rolex manages the entire dial-making process in-house, from the initial design sketches to the final quality inspection. Each stage—whether it involves colouring, finishing, or applying decorative elements—requires specialized expertise. Traditional crafts such as enamelling continue to play an important role, while advanced technologies like magnetron sputtering are also used. This sophisticated process involves depositing an ultra-thin layer of material in a vacuum environment to achieve precise and durable colouring.

By combining time-honoured craftsmanship with cutting-edge innovation, Rolex ensures that every dial meets the highest standards of quality, precision, and longevity—reflecting the brand’s commitment to excellence in every detail.

Diamond-Set Bezel

Precision, Balance, and Lasting Brilliance

The diamond-set bezel demonstrates the refined craftsmanship behind expert gem-setting. Skilled artisans carefully shape the precious metal to create precisely engineered settings, ensuring that each gemstone is securely positioned with accuracy and care. Every diamond is individually placed and aligned in perfect harmony with the surrounding stones, then firmly set within a finely crafted gold or platinum framework.

Beyond the natural quality of the gemstones, Rolex maintains strict standards to achieve exceptional visual symmetry and durability. These include precise control of each stone’s height, accurate orientation and placement, consistent proportions, structural strength, and meticulous finishing of the metal surface. The result is a radiant, well-balanced design that enhances the watch’s elegance and delivers enduring brilliance.

18 ct Yellow Gold

Crafted with Absolute Precision

Rolex maintains full control over the creation of its 18 ct gold by operating an exclusive in-house foundry. This independence allows the brand to produce gold alloys of exceptional purity, consistency, and performance. By carefully adjusting the proportions of silver, copper, platinum, or palladium, Rolex achieves distinct variations of 18 ct gold, including yellow, pink, and white tones.

Only the finest raw materials are selected, and every alloy undergoes rigorous inspection in a modern laboratory equipped with advanced testing technology. From casting to shaping and final finishing, each step is executed with meticulous attention to detail. This comprehensive process reflects Rolex’s commitment to excellence, ensuring that quality begins at the very foundation of every timepiece.

The President Bracelet

A Signature of Prestige and Craftsmanship

The President bracelet reflects Rolex’s dedication to innovation, precision, and refined design. From initial development to final production, both the bracelet and its clasp undergo advanced manufacturing processes and rigorous testing to ensure exceptional strength, reliability, and long-term performance.

In addition to technical excellence, every bracelet is carefully inspected to guarantee outstanding visual quality. Introduced in 1956 for the launch of the Oyster Perpetual Day-Date, the President bracelet is distinguished by its elegant semi-circular three-piece links. It is crafted exclusively from carefully selected precious metals, offering superior comfort, timeless sophistication, and enduring prestige.
