Rolex Datejust 31 Bronze — Diamond Roman VI Roman Dial | Ref. 178344

Reference 178344 presents the Rolex Datejust 31 in a distinctive bronze case, a material choice that lends the watch an organic warmth and an aged-copper patina unique to each individual timepiece. The 31 mm mid-size format bridges the classic Lady-Datejust and the full-sized Datejust 36, offering versatile wrist presence across a range of wearers. The dial is set with diamond hour markers and Roman VI indices, creating a lavishly decorated face that speaks directly to formal and jewellery-adjacent styling.

At its heart, the Ref. 178344 is driven by the Calibre 2235, Rolex's self-winding manufacture movement engineered specifically for the 31 mm Datejust family. The movement features a Parachrom hairspring for enhanced antimagnetic and shock resistance, a Perpetual rotor for efficient winding, and Rolex's patented Paraflex shock absorbers. The Quickset date function at 3 o'clock remains practical and precise, while the Cyclops lens magnifies the date 2.5×.

The bronze case version of the Datejust 31 occupies an unusual niche in the secondary market — less commonly encountered than the standard steel or gold variants, it attracts collectors drawn to patinating metals and a more artisanal aesthetic. The diamond and Roman numeral dial elevates the piece further into jewellery-watch territory. Whether acquired as a wearable or an appreciating collectible, Ref. 178344 rewards the buyer who appreciates rarity within an iconic lineage.
