Rolex Datejust 31 Yellow Rolesor — 46-Diamond Bezel Mother-of-Pearl Roman Dial | Ref. 178383

Reference 178383 occupies a distinct position within the Datejust family as a 31 mm gem-set model rendered in Yellow Rolesor — Rolex's proprietary blend of Oystersteel and 18-carat yellow gold. The combination of a 46-diamond-set bezel and a mother-of-pearl dial with Roman numeral hour markers synthesises the Datejust's enduring architectural elegance with jewellery-grade craftsmanship, producing a piece that transitions seamlessly from formal occasions to everyday refinement.

Powering the watch is Calibre 2235, a self-winding movement with a bidirectional Perpetual rotor and a Parachrom hairspring that delivers exceptional resistance to magnetic fields and thermal variation. The 31 mm Oyster case features the characteristic two-tone aesthetic of Rolesor, with Oystersteel forming the mid-case and 18-carat yellow gold used for the bezel setting, crown, and bracelet centre links. The mother-of-pearl dial, a naturally occurring material unique to each watch, provides luminous depth against the warmth of the gold elements.

For those who prefer a mid-size Datejust with a pronounced jewellery presence, this reference strikes the ideal balance between horological substance and decorative intent. Yellow Rolesor models such as the 178383 have maintained consistent collector interest for their versatility and the visual impact of their gem-set bezels, making them reliable choices on the pre-owned market for buyers who value both heritage and aesthetics.
