Authenticity Guaranteed
We certify all our items as authentic, providing you with a guarantee of quality and craftsmanship.
The Rolex Datejust 31 Steel and Yellow Gold (Ref. 278343) is part of the Datejust line. The Datejust introduced the self-winding wristwatch with a date window in 1945, and the date sits under the Cyclops lens at 3 o'clock. This reference has a 31mm case in Oystersteel and 18k yellow gold. This steel-and-gold combination is what Rolex calls Rolesor, a signature of the brand since 1933.
On the front, the dark grey diamond Roman six dial has diamond hour markers, and uses Roman numerals. The dial is surrounded by a domed bezel set with diamonds. It is worn on the three-piece-link Oyster bracelet.
It is powered by the self-winding Rolex caliber 2236, with roughly 55 hours of power reserve. It is certified as a Superlative Chronometer, Rolex's standard of accuracy within −2/+2 seconds per day once cased. The screw-down crown and sapphire crystal keep it water resistant to 100 meters.
