Rolex Datejust 31 Yellow Rolesor — Silver Diamond Roman Six Dial | Domed Diamond Bezel

Yellow Rolesor — Rolex's proprietary combination of Oystersteel and 18 ct yellow gold — brings a warm two-tone aesthetic to this Datejust 31, a format that has proven perennially popular since its introduction in the mid-20th century. The silver dial features diamond hour markers with Roman numeral six, a configuration that balances classical typography with the brilliance of set stones. The domed diamond bezel adds further sparkle without overwhelming the dial's structured layout.

At 31 mm this Datejust houses Calibre 2236, Rolex's manufacture movement developed specifically for mid-size references. Calibre 2236 incorporates the Syloxi hairspring — a silicon component that improves resistance to magnetic fields and temperature variation — and delivers a 55-hour power reserve. The yellow gold elements of the Rolesor case extend to the crown and the fluted detail of the middle links on the Jubilee bracelet, tying the warm tones together cohesively.

The Datejust 31 in Rolesor occupies a sweet spot in Rolex's catalogue: substantial enough to wear as a statement piece, yet refined enough for daily formal wear. Diamond-dial variants in this configuration are particularly sought after, as the Roman numeral six marker adds a distinctly classical character that plain index dials cannot replicate. For collectors entering the mid-size Datejust market, this configuration represents excellent long-term value.
