Rolex Datejust 31 Everose Rolesor — 24 Diamond Bezel Black Diamond Roman Dial | Ref. 178341

Among the 178xxx Datejust 31 references, 178341 distinguishes itself through the combination of Everose Rolesor — the proprietary blend of stainless steel and 18k Everose gold — with one of Rolex's most statement-forward dial configurations: a black diamond-set dial paired with Roman numeral indices framed by a 24-diamond bezel. This is a reference engineered deliberately for those who regard the watch as the centrepiece of a look rather than a background accessory.

Inside the 31 mm Oyster case sits the Calibre 2235, the predecessor to the current 2236 and a movement with a long track record of reliability in this case size. The two-tone Rolesor construction pairs a stainless steel case body and bracelet centre links with 18k Everose gold crown guards, lugs, and bracelet outer links — a formula Rolex has refined across decades. The dial itself is set with diamonds in place of conventional hour markers, and the Roman numerals provide a classical counterpoint to the gem-set surrounds. The 24-diamond bezel frames the whole composition with continuous brilliance at the chapter ring.

This reference appeals to collectors who value Rolesor construction for its durability advantages over full gold, while still achieving an unambiguously luxurious aesthetic. The 178xxx generation, now superseded by the 278xxx line, represents the last iteration before the Calibre 2236 upgrade, making surviving examples with original components increasingly coherent as a defined collecting tier.
