Authentication on the 6075 is straightforward. Movement should be A.295, dial should read "Oyster Perpetual" with chronometer text but not "Datejust," and the period coronet is the cut-off style. Cases are 18k yellow or pink gold only, with the early milled Datejust bezel and matching Jubilee or Oyster bracelets when bracelet-fitted. A 6075 with later Datejust dial text or a later caliber is a service swap or a misidentified watch.
Authentication on the 6075 is straightforward. Movement should be A.295, dial should read "Oyster Perpetual" with chronometer text but not "Datejust," and the period coronet is the cut-off style. Cases are documented almost exclusively in 18k yellow or pink gold, with the early milled Datejust bezel and matching Jubilee or Oyster bracelets when bracelet-fitted. One real exception is on record: a Bonhams Knightsbridge lot sold a stainless-steel-and-gold 6075 (case No. 613452, movement No. 15308, roulette date wheel, signed case/dial/movement, £3,328 inc. premium) — a single documented example, not evidence the material mix was a regular configuration. A 6075 with later Datejust dial text or a later caliber is a service swap or a misidentified watch.
