All new Rolex watches purchased from one of the brand’s Official Jewelers come with a five-year international guarantee. When you buy a Rolex, the Official Jeweler 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. **Reference** 278343RBR **Model case** Oyster, 31 mm, Oystersteel, yellow gold and diamonds **Bezel** Domed, set with diamonds **Water-resistance** Waterproof to 100 metres / 330 feet **Movement** Perpetual, mechanical, self-winding **Calibre** 2236, Manufacture Rolex **Power reserve** Approximately 55 hours **Bracelet** Oyster, three-piece solid links **Dial** Olive green set with diamonds **Certification** Superlative Chronometer (official chronometer certification + Rolex certification after casing) **Reference** 278343RBR **Model case** Oyster, 31 mm, Oystersteel, yellow gold and diamonds **Bezel** Domed, set with diamonds **Water-resistance** Waterproof to 100 metres / 330 feet **Movement** Perpetual, mechanical, self-winding **Calibre** 2236, Manufacture Rolex **Power reserve** Approximately 55 hours **Bracelet** Oyster, three-piece solid links **Dial** Olive green set with diamonds **Certification** Superlative Chronometer (official chronometer certification + Rolex certification after casing) --- [Download brochure](https://assets.rolex.com/api/brochure/en-us/datejust/m278343rbr-0015.pdf "Rolex datejust Brochure") ## Olive-Green Dial This dial features a large VI set with 11 diamonds. The sunray finish creates delicate light reflections on many dials in the Oyster Perpetual collection. It is obtained using masterful brushing techniques that create grooves running outwards from the centre of the dial. Light is diffused consistently along each engraving, creating a characteristic subtle glow that moves depending on the position of the wrist. Once the sunray finish has been completed, the dial colour is applied using Physical Vapour Deposition or electroplating. A light coat of varnish gives the dial its final look. ![Rolex Datejust 31 in Oystersteel, yellow gold and diamonds with an Olive green Domed, set with diamonds dial, and Oyster bracelet, m278343rbr-0015 - Gandelman](https://www.gandelman.net/rolex/images/model-features/m278343rbr-0015_dial.webp "Rolex Datejust 31 in Oystersteel, yellow gold and diamonds with an Olive green Domed, set with diamonds dial, and Oyster bracelet, m278343rbr-0015 - Gandelman") ## Diamond-set bezel Gem-setters, like sculptors, finely carve the precious metal to hand-shape the seat in which each gemstone will be perfectly lodged. With the art and craft of a jeweller, the stone is placed and meticulously aligned with the others, then firmly secured in its gold or platinum setting. Besides the intrinsic quality of the stones, several other criteria contribute to the beauty of Rolex gem-setting: the precise alignment of the height of the gems, their orientation and position, the regularity, strength and proportions of the setting as well as the intricate finishing of the metalwork. A sparkling symphony to enhance the watch and enchant the wearer. ![Rolex Datejust 31 in Oystersteel, yellow gold and diamonds with an Olive green Domed, set with diamonds dial, and Oyster bracelet, m278343rbr-0015 - Gandelman](https://www.gandelman.net/rolex/images/model-features/m278343rbr-0015_bezel.webp "Rolex Datejust 31 in Oystersteel, yellow gold and diamonds with an Olive green Domed, set with diamonds dial, and Oyster bracelet, m278343rbr-0015 - Gandelman") ## Yellow Rolesor Gold is coveted for its lustre and nobility. Steel reinforces strength and reliability. Together, they harmoniously combine the best of their properties. A true Rolex signature, Rolesor has featured on Rolex models since the early 1930s, and was trademarked as a name in 1933. It is one of the prominent pillars of the Oyster Perpetual collection. ![Rolex Datejust 31 in Oystersteel, yellow gold and diamonds with an Olive green Domed, set with diamonds dial, and Oyster bracelet, m278343rbr-0015 - Gandelman](https://www.gandelman.net/rolex/images/model-features/m278343rbr-0015_material.webp "Rolex Datejust 31 in Oystersteel, yellow gold and diamonds with an Olive green Domed, set with diamonds dial, and Oyster bracelet, m278343rbr-0015 - Gandelman") ![Rolex watches at Gandelman - Aruba](https://www.gandelman.net/rolex/images/rolex-2024/crown-gold.png "Rolex watches at Gandelman - Aruba")### 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 Jewelers, who receive regular deliveries and independently manage the allocation and sales of watches to customers. Gandelman is proud to be part of the worldwide network of Official Rolex Jewelers and can provide information on the availability of Rolex watches.
