Rolex Datejust 31 Yellow Gold — 48 Diamond Bezel White Roman Dial | Ref. 178158

Reference 178158 represents the Datejust 31 at its most opulent — a 31 mm yellow gold case adorned with a factory diamond bezel set with 48 brilliant-cut stones, paired with a white Roman dial that balances classical legibility against the jewelry-grade embellishment. Sitting between the 28 mm Lady-Datejust and the 36 mm full-size model, the 31 mm case has long served collectors who prefer a more refined wrist presence without sacrificing the iconic Datejust silhouette.

Powering the ref. 178158 is Calibre 2235, Rolex's self-winding movement engineered specifically for the mid-size Datejust family. Beating at 28,800 vph, the movement incorporates a Parachrom hairspring for enhanced resistance to magnetic fields and shock, along with the Paraflex shock absorbers introduced to improve overall robustness. The 18 ct yellow gold case, fluted or smooth crown guards, and a Jubilee or Oyster bracelet in matching gold complete a composition that is unambiguously precious in character.

For collectors, the 178158 occupies a compelling position as a full-gold mid-size Datejust with diamond hardware — desirable as a daily companion for those who prefer a subtler case diameter than the 36 mm norm, yet entirely uncompromising in material quality. Its combination of yellow gold and diamond bezel speaks to a buyer who values traditional Rolex craftsmanship over contemporary sportiness, and examples in excellent condition with original bracelet and documentation consistently attract strong secondary-market interest.
