In the early 1960's the marking is still the same, like on this Explorer reference 1016:

Submariner ref. 5513:

This 1655 Freccione:



or this Cosmograph ref. 6263:



In the seventies, some rare birds have obviously been issued: here are several examples of Red Submariner ref. 1680 and Double Red Sea Dweller ref. 1665, with a Tiffany & Co. marking that may be either white or red:

A more important number of watches has been issued in the "sapphire era" until the early 1990's. These watches can more easily be found with the original box and papers. The box is a specific light green box and the papers bear the name of the retailer.Here's a rare Submariner ref. 16800:
