Rolex blue dial

A blue dial Rolex typically comes with a 5-year warranty from the manufacturer, not just one year. This warranty covers manufacturing defects in materials and craftsmanship but doesn't extend to damage caused by accidents, misuse, or external factors.

If you're referring to a pre-owned Rolex with a 1-year warranty, this may be a warranty offered by the retailer or an authorized reseller rather than the standard Rolex warranty. Always check with the seller for specifics about the warranty.
