The 6031 is a one-year 1949 reference and the pink-gold twin of ref 6030. It is one of the four references Le Monde Edmond names under the narrow “true Ovettone” reading — alongside [[Reference:4467|4467]], 6074, and [[Reference:6075|6075]] — and the only pink-gold entry in that cluster. Architecturally it returns to the 4467 idiom after the one-year experimental 5030/5031 pair~~: the~~ curved case flanks are back, the fine milled bezel is back, and the movement is still Cal. A.295. ~~What’s~~ new is the slightly larger crown and the settling of the Ovettone form into the shape it holds for the rest of the pre-Datejust-text era.

== What the 6031 is ==

The 6031 is a pink-gold 36mm Big Bubbleback Datejust made for approximately one year in 1949. It comes after the transitional 5030/5031 pair and before the 1950 platinum 6074 and the 1950–1953 yellow-gold 6075. Within the Ovettone line it occupies the position where the architecture settles~~: the~~ 4467’s curvier case flanks return, the bezel is the fine milled gold the 4467 used, and the crown is the larger Brevet that carries through the rest of the pre-6105 era. Cal. A.295 is unchanged from the 5030/5031 and the 4467.

A.295 is unchanged from the 5030/5031 and the 4467.

What makes the 6031 specifically notable in collector literature is its inclusion in the narrow “true Ovettone” cluster. Le Monde Edmond’s reading restricts the term to four references — 4467, 6031, 6074, 6075 — on the grounds that those four share the fully-settled Ovettone form and avoid the transitional 50xx experiments. Under the broader Italian auction usage (Pandolfini, Aste Bolaffi) and mainstream dealer copy, the Ovettone family also includes 5028, 5030, 5031, and 6030. The 6031 is the only reference that appears under both definitions as a pink-gold example.

== Pink gold and configuration ==

The 6031 is pink-gold only; the yellow-gold twin carries ref 6030. Dial configurations follow the broader Ovettone conventions with pink-gold matching: silvered or eggshell dials with applied pink gold dagger markers, pink gold alpha hands with radium inserts on lumed configurations, plain polished pink gold hands on dress configurations. Bubbleback coronet variants — including the “cut-off” truncated form — are documented alongside the full coronet; Chronometer and Certified Chronometer text above six on chronometer-grade examples.

Bubbleback coronet variants, including the “cut-off” truncated form, are documented alongside the full coronet. Chronometer and Certified Chronometer text above six on chronometer-grade examples.

Date wheels on 6031 examples are typically black on white. Roulette wheels (alternating red/black) appear sporadically in the broader Ovettone window and are documented on some 60xx peer examples. Period-correct bracelets are the 18K pink gold Jubilee or a leather strap with pink gold buckle.

Cal. A.295, unchanged from the 5031 and the 4467. 29.5mm diameter. Parts-catalogue cross-listings are Cal. 740 (base) and Cal. 745 (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. Dial feet positions are specific to the A.295 and differ from the A.296 that carries the 6105 and later references.

The A.295 → A.296 transition matters for authentication on adjacent references (a 6031 dial on a 6105 movement is not period-correct) but does not affect the 6031 itself, which is firmly inside the A.295 generation.

== Authentication priorities ==

Movement should be Cal. A.295 (Cal. 740 or Cal. 745 in parts-catalogue form); a later caliber in a 6031 case is a service swap. Case metal is 18K pink/rose gold throughout — case, crown, bezel, markers, hands, bracelet — and a yellow-gold example is ref 6030, not 6031. Case flanks are curved between the lugs, the 60xx signature; straight flanks on a claimed 6031 suggest a 5031 misidentification. The crown is the larger Brevet, matching pink gold, not the 50xx small crown. The bezel is fine milled or reeded pink gold. The dial reads "Oyster Perpetual" with Chronometer or Certified Chronometer above six on chronometer-grade examples, and no "Datejust" text. Dial feet position is specific to A.295.
