Dark Rhodium Dial
The sunray finish on Rolex dials is a predominant method in watchmaking of achieving pure metallic colour dials such as shades of silver grey, rhodium or ruthenium.
The Fluted Bezel
The Rolex fluted bezel is a mark of distinction. Originally, the fluting of the Oyster bezel had a functional purpose: it served to screw the bezel onto the case helping to ensure the waterproofness of the watch. It was therefore identical to the fluting on the case back, which was also screwed onto the case for waterproofness, using specific Rolex tools. Over time, the fluting became an aesthetic element, a genuine Rolex signature feature. Today the fluted bezel is a mark of distinction, always in gold.
18 ct Everose gold
To preserve the beauty of its pink gold watches, Rolex created and patented an exclusive 18 ct pink gold alloy cast in its own foundry: Everose gold. Introduced in 2005, 18 ct Everose is used on all Rolex Oyster models in pink gold.
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.
Official Rolex Time Midas is proud to be part of the worldwide network of Official Rolex Retailers and can provide information on the availability of Rolex watches.
The classic Rolex Datejust is the archetype of the modern watch, thanks to aesthetics and functions that transcend changes in fashion. This year, Rolex presents four new white Rolesor versions (combining Oystersteel and 18 ct white gold) of the Datejust 31. Aesthetically, the Datejust has spanned eras, while retaining the enduring codes that make it one of the most recognized and recognizable of watches.
