Thanks! Do you know if either of those will fit on the 44mm submersible or only the Luminor case?
The new style bracelets can be different and go both to the bettarini case (for example, PAM299), and to the old 1950 case (for example, PAM329). The SEL will differ (by the way, they are removable, separate). But REP bracelets are almost always adjusted with end links for a good fit to a specific watch, and on others they may not sit so comfortably. As for other 1950 cases, for example, on 44mm submersibles, then everything is individual, and there will be no guarantee of a good fit, or even a basic fit, because the shape of the end of the case is different, and the factories do not have bracelets made for submersibles. Especially if you mean some 1950 case for p.9010, which has a unique end shape (it is thicker and has a different proportion of the end width along the planes between the lugs than gen).
