Frequently asked questions about Submariner and Daytona references
Both the Submariner and Daytona have black ceramic bezels—do they function the same?
No. The Submariner has a unidirectional 60-minute dive bezel; the Daytona has a tachymetric bezel for its chronograph.
Do the LN of 126610LN and 126500LN represent the same series?
No. LN is a suffix within the reference number that indicates a black configuration. The complete reference and series name establish the model.
Can box and papers from another Rolex of the same period be treated as original?
No. Accessories must match the reference number, purchase date, region and provenance of the watch. Clearly disclose anything paired later.
