Reference:6031: Difference between revisions

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.

Total production is not published by Rolex. The 1949 window is short and surviving examples are scarcer than the 4467 or 6075; the precise production count is not publicly documented.

The narrow and broad Ovettone definitions both include the 6031. The narrow reading (Le Monde Edmond) names four "true Ovettone" references and the 6031 is one of them. The broader reading (Italian auction usage) covers the full 5028–6075 range and the 6031 is inside it too.

Pink gold survival rate sits below yellow gold because pink alloys of the period were softer and were often polished heavily at service. No confident ratio has been published for the 6031 specifically.
