The early cushion-case Oyster references used manual movements, but the available catalogue descriptions do not support one movement assignment for every reference. For [[Reference:1069|ref. 1069]], Antiquorum describes a 15-jewel 11-ligne manual movement on its 2003 example; Christie's describes an unnamed 15-jewel lever movement, and a dealer-photographed example shows a 17-jewel Rolex movement. Keep each description with its watch. Aste Bolaffi's Marconi Oyster has a 15-jewel FHF 30-based movement and the number 1069 on its case, but the catalogue does not identify that number as the reference.

For [[Reference:1072|ref. 1072]], Antiquorum describes 10-ligne, 18-jewel movements in two examples. Bonhams calls a separate example a 15-jewel Prima. Cool Auction labels the movement Cal. 10½ and reports 15 jewels, 18,000 beats per hour and a maximum 38-hour reserve on a Bucherer-signed watch. The same dealer attributes a Superbalance and Breguet hairspring to that movement. Hess Fine Auctions reports a manual 15-jewel movement in its 2023 lot. Watch Collecting describes another example as manual-wind but gives no caliber or jewel count. Toovey’s title calls its circa-1938 example Ultra Prima but gives no movement specification. The Cool Auction caliber label has no corroboration in the other records; the lots do not establish a single movement assignment or grade across the reference.
