Rolex Datejust 31 White Rolesor — 46 Diamond Bezel Blue Index | Ref. 178384

Another configuration of reference 178384, this Datejust 31 in White Rolesor pairs the 46-stone factory diamond bezel with a blue index dial — a combination that shifts the overall character of the piece toward a cooler, more contemporary palette. Blue dials across Rolex's Datejust range have attracted growing collector interest over the past decade, and within the 31 mm size this variant stands out by contrasting the cool diamond bezel with a rich blue ground that reads differently depending on light conditions. The 31 mm Oyster case in White Rolesor occupies a practical intermediate position between the 28 mm Lady-Datejust and the 36 mm unisex standard.

Calibre 2235 drives this reference — the established automatic movement for the 31 mm class, built on Rolex's in-house architecture with a Parachrom hairspring, Paraflex shock protection, and 48 hours of power reserve. The bidirectional Perpetual rotor maintains reliable winding during daily wear. Case construction adheres to Oyster standards, with a screwed-down crown and screw-in case back providing 100 metres of water resistance. The Jubilee bracelet in steel and white gold links provides a supple fit and is an appropriate complement to the dressed character of the diamond bezel configuration.

Buyers comparing the blue index variant to the silver dial version of 178384 often find that the blue dial commands a modest secondary market premium, reflecting its relative scarcity and the enduring demand for blue-dialed Rolex pieces. The 46-diamond bezel on this smaller case creates a proportionally striking effect. Prospective buyers should confirm the factory-original status of the diamond setting, as aftermarket modifications in this price tier are not uncommon and significantly affect resale value.
