Dark gray dial
The dial has an 18K gold base set with diamonds. Many dial styles in the Oyster series use the sunray effect to reflect an elegant luster. This effect requires extraordinary brushing techniques to create engravings that extend outward from the center of the dial. The light is dispersed along the engraving, creating a subtle and unique effect, showing different luster as the wrist moves. After the solar ray effect process is completed, the dial is added with color through physical vapor deposition or electroplating technology, and is finally decorated with varnish.
Triangular grooved outer ring
Rolex’s triangular pit pattern is a characteristic of the brand’s watches. Initially, the triangular grooves on the Oyster outer ring served a practical purpose, helping to tighten the outer ring to the case and ensure the waterproof performance of the watch. The pit design of the bottom cover is also based on the same considerations, and is screwed to the case with specific Rolex tools. Later, the triangular pit pattern evolved into an aesthetic design element and became a signature feature of Rolex. To this day, the triangular pit pattern has become a characteristic of the brand's watches. The outer ring of this Datejust 31 is made of gold.
18K gold
Rolex has its own foundry to cast high-quality 18K gold alloy. By mixing different amounts of silver, copper, platinum or palladium, different types of 18K gold can be extracted: yellow gold, pink gold or white gold. All raw materials are made from high-purity metals. Before the gold is formed, they must be carefully tested with advanced equipment in the self-operated laboratory. Each process is meticulous. The unremitting pursuit of excellence since the beginning of production is Rolex's consistent insistence.
Model Availability
All Rolex watches are assembled by hand with the utmost care to ensure exceptional quality. Such high standards naturally restrict Rolex production capacity and, at times, the demand for Rolex watches outpaces this capacity.
Therefore, the availability of certain models may be limited. New Rolex watches are exclusively sold by Official Rolex Retailers, who receive regular deliveries and independently manage the allocation and sales of watches to customers.
Unique Timepieces Watches Holidings Limited is proud to be part of the worldwide network of Official Rolex Retailers and can provide information on the availability of Rolex watches.
