Rolex Datejust 34 Gold — 12 Diamond Bezel Purple Diamond Roman VI Dial | Ref. 81315

Reference 81315, the Datejust 34 in 18 ct gold, occupies a now-discontinued mid-size niche that Rolex no longer actively produces — a 34 mm Oyster case that sits between the current 31 mm and 36 mm standards. This particular example is appointed with one of the most vivid dial configurations ever to appear in the Datejust range: a purple diamond-set dial with Roman VI numeral in a twelve-diamond-set bezel, an arrangement that speaks directly to Rolex's tradition of high jewellery watchmaking.

Driving this reference is a movement from Rolex's mid-size calibre family, engineered to the same chronometric standards that define the entire Datejust line. The gold Oyster case provides 100 m water resistance, and the traditional triplock crown ensures the integrity of the seal. The diamond-set bezel — twelve stones precisely set at each hour position around the flange — adds both sparkle and structural elegance, while the purple dial retains the chromatic rarity that made this colour a long-standing collector favourite.

As a discontinued 34 mm reference in solid gold with an unusual purple dial, the 81315 possesses multiple layers of collectibility. The case size itself is sought by collectors who find the 31 mm too delicate and the 36 mm too substantial; the purple dial colour is among the most distinctive in Rolex's history; and the solid gold construction ensures intrinsic material value. For the dedicated Datejust archivist, this reference represents a fascinating chapter in Rolex's pre-rationalisation catalogue.
