Our take on the Rolex Steel and White Gold Datejust 31 - Domed Bezel - Silver Index Dial - Oyster Bracelet — Ref. 278240

The Datejust 31 ref. 278240 is a midsize Rolex with a 31 mm Oystersteel case, an 18k white gold domed bezel and a silver dial with applied index markers. It runs on the self-winding caliber 2236 with about 55 hours of power reserve and is certified as a Superlative Chronometer to −2/+2 seconds a day. The date sits under the Cyclops lens at 3 o'clock, and the watch is water resistant to 100 meters. It suits someone who wants a smaller, dressier Rolex that still works daily; against the fluted-bezel Datejust 31 and two-tone Rolesor versions, the domed white gold bezel and all-steel case read quieter and less flashy.

About the Rolex Steel and White Gold Datejust 31 - Domed Bezel - Silver Index Dial - Oyster Bracelet — Ref. 278240

The Rolex Datejust 31 (reference 278240) is a self-winding wristwatch with a 31 mm case in Oystersteel and 18k white gold. Rolex calls this steel-and-gold combination Rolesor. The date shows in a window at 3 o'clock under a Cyclops lens.

The silver dial has applied index hour markers, and a polished domed bezel surrounds it. The watch is fitted with an Oyster bracelet with three-piece links.

It runs on the self-winding Rolex caliber 2236, with a power reserve of about 55 hours. It is certified as a Superlative Chronometer, with accuracy of −2/+2 seconds per day once cased. A screw-down crown and a sapphire crystal give it water resistance to 100 meters.

Questions and answers

Is the 31 mm case too small for a man?
It depends on wrist size. At 31 mm the Datejust reads as a dress watch on most men's wrists; many prefer the 36 mm or 41 mm Datejust. It is a common size for women and for men who like a smaller watch.
What is the difference between this and a fluted-bezel Datejust 31?
This ref. 278240 has a polished domed bezel in 18k white gold. Fluted-bezel Datejust 31 models use a different bezel finish and reference. The domed bezel is the quieter, less reflective look.
How accurate is the caliber 2236?
Rolex certifies it as a Superlative Chronometer at −2/+2 seconds per day once cased. That is tighter than the COSC chronometer standard.
What is the power reserve?
About 55 hours when fully wound. That covers a weekend off the wrist without stopping.
Is it safe to swim with?
Yes. The screw-down crown and sapphire crystal give 100 m water resistance, which covers swimming and showering. It is not a dive watch, so avoid deep diving.
What comes in the box?
A Rolex watch is normally supplied with its presentation box, warranty card and manuals. Confirm the specific contents and card date with the seller before buying.
