Tudor Watch Dimensions: Diameter, Thickness, Lug-to-Lug

Tudor sizing follows two case families: the heritage Black Bay 39/41 with vintage proportions, and the modern Pelagos tool-watch line in titanium. Black Bay 58 (39mm × 11.9mm) sits as the reference small-diver pick; Pelagos 39 trades the gilt look for full-titanium 11.8mm thickness in the same diameter.
