Band: Steel Clasp: Rolex branded folded steel Glass: Hardlex mineral glass Water Resistant: Splash Proof When Hans Wilsdorf launched Tudor in 1952, he made the new marque an unusual promise: it would share two of Rolex's own inventions, the waterproof Oyster case and the self-winding (automatic) Perpetual rotor. Wilsdorf said he would allow no other watch that privilege. Tudor built on it by pairing those Rolex-made cases, crowns, and bracelets with movements bought in from established Swiss suppliers, rather than Rolex's own workshops. This aloowed the watches carry Rolex's quality at a friendlier price. The automatic line was named Prince, Tudor's own answer to Rolex's Perpetual. This 1977 example, reference 9101, follows that formula closely. The case is 38 mm across, in stainless steel pressure resistant to 10 bar (100 metres) when new.

Power comes from a Tudor-decorated ETA calibre 2784, an ébauche-based movement rather than an in-house Tudor design. It offers a 42-hour power reserve and runs at 4 Hz (28,800 vibrations per hour), with hacking seconds and a quick-set date.
