Superlative Chronometer certification
Like all Rolex timepieces, the Yacht-Master is covered by the Superlative Chronometer certification. This designation testifies that every watch leaving the brand’s workshops has successfully undergone a series of tests conducted by Rolex in its own laboratories, according to its own criteria.
The Superlative Chronometer status is symbolized by a green seal and is coupled with an international five-year guarantee.
