To ensure the precision and reliability of its timepieces, Rolex submits each watch after assembly to a stringent series of tests. All new Rolex watches purchased from one of the brand’s Official Retailers come with a five-year international guarantee. When you buy a Rolex, the Official Retailer fills out and dates the Rolex guarantee card that certifies your watch’s authenticity.

The five-year guarantee which applies to all Rolex models is coupled with the green seal, a symbol of its status as a Superlative Chronometer. This exclusive designation attests that the watch has successfully undergone a series of specific final controls by Rolex in its own laboratories according to its own criteria, in addition to the official COSC certification of its movement.
Every Rolex is delivered in a beautiful green presentation box that is both protector and keeper of the jewel that nests inside it. As the presentation box is also a symbol of giving, it is important, if you are purchasing a gift, that the recipient’s first contact with their Rolex sets the stage for revealing what lies within.

24-Hour Rotatable Bezel

This model features a black dial and a two-colour Cerachrom bezel insert in grey and black ceramic. In addition to conventional hour, minute and seconds hands, the GMT-Master II features an arrow-tipped hand, which circles the dial once every 24 hours, as well as a bidirectional rotatable 24-hour graduated bezel. The distinctively coloured 24-hour hand displays the “home” reference time in a first time zone which can be read on the graduations on the bezel. The traveller’s local time is easily set by “jumping” from hour to hour, thanks to an ingenious mechanism operated via the winding crown: the hour hand can be adjusted forwards or backwards independently of the minute and seconds hands. This allows travellers to adapt to their new time zone without affecting the precision of their timekeeping.

Black dial

Like all Rolex Professional watches, the GMT-Master II offers exceptional legibility in all circumstances, and especially in the dark, thanks to its Chromalight display. The broad hands and hour markers in simple shapes – triangles, circles, rectangles – are filled with a luminescent material emitting a long-lasting glow.

18 ct yellow 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 out-paces 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.

Simone Ventures is proud to be part of the worldwide network of Official Rolex Retailers and can provide information on the availability of Rolex watches.
