Authenticity Guaranteed
We certify all our items as authentic, providing you with a guarantee of quality and craftsmanship.
Reference 278240 is the Rolex Datejust Steel and White Gold 31. 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. The 31mm case is made of Oystersteel and 18k white gold. This steel-and-gold combination is what Rolex calls Rolesor, a signature of the brand since 1933.
The dark grey Roman dial uses Roman numerals. The dial is surrounded by a polished domed bezel. The case is paired with the five-piece-link Jubilee bracelet.
It is powered by the self-winding Rolex caliber 2236, with roughly 55 hours of power reserve. Every movement of this generation is tested as a Superlative Chronometer, accurate to within −2/+2 seconds a day. The screw-down crown and sapphire crystal keep it water resistant to 100 meters.
