	Italian auction houses (Pandolfini, Aste Bolaffi) and mainstream dealer usage include the 5030/5031 pair in the Ovettone family, alongside Edmond ~~Saran’s~~ 2022 Le Monde Edmond treatment that names the 5030 explicitly. The narrower dealer convention excludes the 50xx pair and reserves the term for 4467, 6031, 6074, and 6075. Both framings coexist in current literature.

	Case architecture on the 5031 is identical to the 5030 and follows the same two one-year deviations from the 4467 and 60xx standard: the perfectly straight flanks between the lugs, and the small Brevet crown carried over from the 32mm small Bubblebacks. Three-piece Oyster construction, 36mm diameter, domed caseback housing the Perpetual rotor, fine milled/reeded bezel. In pink gold the straight-flank profile reads slightly differently on the wrist than it does in yellow (the pink ~~alloy’s~~ warmer tone softens the visual angularity) but dimensionally the case is the same.

	The crown on the 5031 is the small screw-down Brevet in matching pink gold, cross-center, ~~“Rolex~~ + ~~Oyster”~~ marking. By the 1949 60xx generation, Rolex had switched to a larger crown that sat more naturally on the 36mm case. The 5031 is the one pink-gold Big Bubbleback that still wears the old small crown; the 6031 that replaces it in 1949 wears the new one.

	The 5031 is pink-gold only. Period-correct dials match the case metal: silvered or eggshell dials with applied pink gold dagger markers, pink gold alpha hands with radium inserts on the lumed configurations, plain polished pink gold hands on dress configurations.

	== What the 5031 is ==		== What the 5031 is ==

	The 5031 is ~~a 36mm Big Bubbleback Datejust in 18K~~ pink gold~~, made for approximately one year in 1948. Structurally it shares~~ the 5030 ~~at every level~~: ~~case shape~~, movement, ~~bezel, crystal, crown style, dial architecture. The difference is case metal and~~, ~~by extension, matching hands and markers~~ in pink gold. Within the Ovettone sequence the 5031 occupies the same position as its yellow-gold twin, directly after the 4467 and directly before the 60xx references. [https://le-monde-edmond.com/datejust-a-closer-look-at-a-rolex-icon-2/ Le Monde Edmond] (2022) and Italian auction houses use "Ovettone" for the whole Big Bubbleback cluster including the 50xx pair; the narrower dealer reading restricting the term to 4467/6031/6074/6075 would exclude the 5031.		The 5031 is the pink-gold twin to the 5030: same 36mm Big Bubbleback Datejust architecture, same movement, same transitional place in the line, but in 18k pink gold.

	Pink and rose gold dress watches were a European preference through the 1940s. Markets in France, Italy, Switzerland, and German-speaking Europe favoured pink for formal wear, and Rolex produced pink-gold twins of most Ovettone references to meet that demand. Survival rates on the pink variants run below yellow, because pink alloys of the period were softer and more prone to polishing-out at service.

	== Movement: Cal. A.295 ==		== Movement: Cal. A.295 ==

	Same as the 5030: ~~Cal~~. A.295, the automatic movement that powered the 4467 from 1945 and carries through the 50xx transitional pair into the 6030/6031 of 1949. 29.5mm diameter (the “295”). Rolex parts catalogues cross-list the movement within the 740 / 745 family~~: Cal. 740 for the base grade, Cal. 745 for the Chronometer grade. Self-winding Perpetual rotor, 18 jewels, Rolex Superbalance, Breguet overcoil hairspring~~, center seconds, date~~. No~~ shock protection~~. No quickset. Slow creep at midnight~~ rather than ~~instantaneous snap-change; the~~ snap-change ~~arrives with Cal. 1065 in 1956–57 and ends the Bubbleback silhouette~~.		Same as the 5030 mechanically: cal. A.295 in the 740/745 family, with center seconds, date, no shock protection, and the old slow date change rather than a later snap change.

	Dial feet positions are specific to the A.295 and differ from the A.296 used in ref 6105 and later. A 5031 dial on an A.296 movement is not period-correct. The Vintage Rolex Forum documentation by specialist Xeramic (thread t-274914) is the standard reference on this check.
