Diamonds, sapphires, rubies, emeralds - the noblest and most precious stones are selected to grace Rolex timepieces. The brand has in-house expertise and equipment enabling it to bejewel any model in its catalogue. Experienced gemmologists first select gemstones of the highest quality. For this, they can rely on their own seasoned judgement as well as state-of-the-art analysis equipment. The stones are then entrusted to the gem-setters, who skilfully place each precious stone onto the watch by hand, one by one, assuring precision to within hundredths of a millimetre. Such stringent tolerances guarantee that each stone shines with optimal brilliance and is perfectly aligned with those around it. These time-honoured gestures, which may be repeated many hundreds of times, ensure that each gem-set watch produced by Rolex sparkles with exceptional intensity and reflects the standard of excellence required by the brand.

The Yacht-Master's bidirectional rotatable 60-minute graduated bezel is made entirely from precious metals or fitted with a Cerachrom insert in high-tech ceramic. The raised polished numerals and graduations stand out clearly against a matt, sand-blasted background. This functional bezel - which allows the wearer to calculate, for example, the sailing time between two buoys - is also a key component in the model's distinctive visual identity.

The Yacht-Master's new Oysterflex bracelet, developed by Rolex and patented, offers a sporty alternative to metal bracelets. The bracelet attaches to the watch case and the Oysterlock safety clasp by a flexible titanium and nickel alloy metal blade. The blade is overmoulded with high-performance black elastomer which is particularly resistant to environmental effects, very durable and perfectly inert for the wearer of the watch. For enhanced comfort, the inside of the Oysterflex bracelet is equipped with a patented longitudinal cushion system that stabilizes the watch on the wrist and fitted with an 18 kt Everose gold Oysterlock safety clasp. It also features the Rolex Glidelock extension system, designed by the brand and patented. This inventive toothed mechanism, integrated beneath the clasp, allows fine adjustment of the bracelet length by some 15 mm in increments of approximately 2.5 mm, without the use of tools.
