How does the Datejust 31 compare with the Datejust 36?

The 31 is smaller and lighter on the wrist, aimed at smaller wrists and buyers who want a subtler look. The 36 has more wrist presence and a wider choice of dials and configurations.

Is the Datejust 31 suitable for daily wear?

Yes. It is automatic, water resistant to 100 m and available on Oyster or Jubilee bracelets, so it handles everyday use. Many owners wear it as their only watch.

What movement does it use?

It uses a Rolex automatic movement, chronometer-certified, with a date function. Exact calibre and power reserve vary by production year.

Does it hold its value?

Rolex models generally retain value well on the secondary market, and the Datejust is one of the brand's most recognized lines. Resale depends on configuration, condition and box and papers.

A new Datejust typically comes with the watch, its box, warranty card and manuals. Confirm the contents with the seller, especially for pre-owned pieces.
