Rolex Datejust 31 Yellow Gold — Olive Green Diamond Dial | Ref. 278248

The Datejust 31 in yellow gold occupies a precise position within Rolex's mid-size offering — substantial enough to carry presence on the wrist yet refined enough to read as an explicitly dressy piece. Reference 278248 pairs an 18 ct yellow gold Oyster case with an olive green dial set with diamond hour markers, a combination that grounds the watch in naturalistic luxury without surrendering to ostentation. The 31 mm diameter has long been the sweet spot for wearers who want the full Datejust design language in a format that bridges formal and everyday contexts.

Power comes from the Calibre 2236, Rolex's proprietary movement developed for the mid-size Datejust family. The 2236 runs at 28,800 vph, incorporates a Syloxi silicon hairspring for enhanced magnetic resistance and thermal stability, and delivers a 55-hour power reserve — figures that place it firmly in the modern performance tier. The yellow gold case is fitted with a fluted or smooth bezel appropriate to the reference, and the Jubilee or Oyster bracelet in matching gold completes the integrated aesthetic that Rolex has refined over decades.

For collectors, 278248 represents an entry into full precious-metal Datejust territory with the added visual interest of a dial that departs from more conventional white or silver options. The olive green and diamond combination appeals to buyers seeking something distinctive without straying into avant-garde territory. Resale values for yellow gold Datejust 31 references have remained resilient, and factory diamond dials typically carry a premium over aftermarket stone-set alternatives. This is a compelling choice for anyone building a versatile fine-watch wardrobe.
