The Cosmograph Daytona is Rolx's most sought-after chronograph, and this 40 mm version in 18 ct yellow gold is one of the most eye-catching. The champagne dial has three black subdials that make it easy to read the 30-minute counter, the 12-hour counter, and the running seconds. Gold hour markers and hands are filled with Chromalight luminescence for legibility in low light. The black Cerachrom ceramic bezel resists scratches and fading, and its tachymetric scale measures average speed over a fixed distance.
Rolx's Oysterflex bracelet pairs flexible metal blades with black elastomer, so it's as comfortable as a rubber strap and as sturdy as metal. It adjusts with the Glidelock extension system and closes with the Oysterlock safety clasp. The watch is powered by Rolx's self-winding Calibre 4131, with about 72 hours of power reserve, and it's water resistant to 100 metres.
