	The full Ovettone arc runs: 4467 (1945) → 5028 / 5030 / 5031 (1947–48) → 6030 / 6031 (1949) → 6074 / 6075 (1950) → 6105 (1953, first ~~“Datejust”~~ text) → 6305 (1954, first Cyclops) → 6604 / 6605 (1956–57, first instantaneous date via Cal. 1065).

	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. Bubbleback-style coronet logos — often the ~~“cut~~-~~off”~~ truncated variant — and Chronometer or Certified Chronometer dial text above six on chronometer-grade examples are both documented.

	Date wheels follow the broader Ovettone convention: typically black on white by the 5031 era, with roulette (alternating red/black) wheels documented on some peer examples in the same window. A 5031 with a roulette wheel is not impossible, but it is less common than on earlier 4467 examples.
