Tudor Chronograph 7159

The case measures 40mm across, with a 20mm lug width. Case material: Steel. Case size alone is a poor guide to how a watch wears; lug-to-lug length and how the bracelet drops off the case matter more, which is why we suggest trying one on before you commit.

Manual wind, Valjoux 7734. It beats at 18,000 vph. The movement uses 17 jewels.

Tudor produced this reference from 1971 to 1977. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.
