| [[Reference:6106|6106]] || Auction examples dated 1951 and circa 1952 || Antiquorum identifies Cal. 645; Monaco Legend uses A260, a size-family code shared with Cal. 645 || Steel 34 mm examples with several dial layouts, including a 3-6-9 dial described as Explorer-style. Production span and dial originality are not established

|-

| [[Reference:6502|6502]] || Auction examples mostly dated to the 1950s; case 994893 has a circa-1964 auction date that conflicts with its circa-1954 serial-chart estimate || Cal. 1030 in auction catalogues and Watch-Wiki || No-date, gold Oyster Perpetual, 34–35 mm in catalogues. The article consolidates duplicate case 36675 and explains the disputed 6502/6603 attribution for case 36701
