Rolex Submariner Date 126618LB

The case measures 41mm across, with a 21mm lug width. Case material: Solid 18k yellow gold. 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. 3235. Power reserve is 70 hours. It beats at 28,800 vph. The movement uses 31 jewels.

It is rated to 300 meters, about 984 feet. That is a diving rating: it is built for scuba use, not just for getting wet. One caution that applies to every watch on this page: a water resistance figure describes a new watch with fresh gaskets. On a piece that is years past its last service, treat the rating as unknown until it has been pressure tested.

Rolex produced this reference from 2020 to the present day. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.

126 = current Submariner case generation; 618 = solid yellow gold model; LB = Lunette Bleue (blue bezel). 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.

18k yellow gold, blue dial/bezel. Collector nicknames are not official Rolex names, but they are what people actually search for and what they are called across a showroom.
