Common questions about the Rolex Day-Date 6510

How big is the Rolex Day-Date 6510?

The case measures 36mm across. Case material: 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.

What movement is in the 6510?

Automatic (Perpetual). The caliber is the Rolex 1055. It beats at 18,000 vph. The movement uses 25 jewels.

When was the Rolex Day-Date 6510 made?

Rolex produced this reference from 1956 to 1957. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.

Does the 6510 have a nickname?

Day-Date 36. Collector nicknames are not official Rolex names, but they are what people actually search for and what they are called across a showroom.
