The Cosmograph Daytona 126508 earned its “John Mayer” nickname after the musician and watch collector was repeatedly spotted wearing this green-dial, yellow-gold reference. The combination of a vivid green sunburst dial against an 18k yellow gold case proved so popular that the 126508 became one of the most discussed Daytona variants of its generation, sitting alongside the Paul Newman as a pop-culture touchstone.

The 126508 Up Close
The green sunburst dial radiates depth as light moves across its surface. Three champagne gold subdials — small seconds at six, 30-minute counter at three, and 12-hour totaliser at nine — create a warm contrast against the green. A matching green Cerachrom bezel with moulded tachymeter scale ties the dial colour into the case exterior.
The 40mm yellow gold case connects to a matching three-piece link Oyster bracelet with an Oysterclasp featuring Easylink comfort extension. The weight and warmth of full yellow gold distinguish this reference from steel Daytonas. See all chronograph references in the Daytona collection.
Movement
An automatic chronograph movement drives the central chronograph seconds hand and two sub-counters for elapsed minutes and hours. The column-wheel mechanism provides crisp engagement, and the small seconds at six o’clock run independently of the chronograph start-stop function.
