ZF is one of the most frequently used factory labels in dealer catalogues (37 of 1,285 listings in the snapshot this site checked), and is usually described as a generalist covering Audemars Piguet, Tudor, Breitling and Rolex references. There is no published test of ZF comparable to the RWI 2026 Submariner comparison, so nothing here about its quality comes from a measured source. Buyers should treat "ZF" as a label on a listing rather than a verified identity.
