Rolex Oyster Perpetual Date 34 15505

The case measures 34mm across, with a 19mm lug width. Case material: 14K yellow gold shell (gold-filled case over steel base). 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.

Automatic, Rolex Cal. 3035. Power reserve is 42 hours. It beats at 28,800 vph. The movement uses 27 jewels.

Rolex produced this reference from 1977 to 1986. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.

155 = Date 34mm 5-digit; 05 = 14K gold shell case. Reading the reference is the fastest way to confirm that a watch is what the seller says it is, before you get anywhere near the movement.
