The Cosmograph Daytona 126509 delivers a bright blue sunburst dial inside a full 18k white gold case and bracelet. Where most precious-metal Daytonas pair with Oysterflex rubber, this reference keeps a traditional three-piece link Oyster bracelet in matching white gold, giving it a more classic, integrated look. The blue dial radiates depth and dimensional shifts that flat-colour dials cannot replicate, making the 126509 one of the most photogenic references in the current Daytona catalogue.

The 126509 Up Close: Case, Dial and Bracelet
The bright blue sunburst dial plays with light in ways that photographs struggle to capture. Under direct illumination, the dial flashes a vivid electric blue; in shade, it deepens toward navy. Three silver-toned subdials — small seconds, 30-minute counter, and 12-hour totaliser — sit recessed into the blue surface. Applied white gold hour markers with luminescent fill ensure legibility in low light.
The steel-colour Cerachrom bezel insert gives the appearance of brushed stainless steel while retaining the scratch-resistance of ceramic. The white gold Oyster bracelet terminates in an Oysterclasp with Easylink comfort extension. Compare all white gold Daytona references in the Daytona collection.
Movement
An automatic chronograph movement powers the central chrono seconds hand, 30-minute counter at three, and 12-hour totaliser at nine. The column-wheel design delivers crisp pushpiece feel during start, stop, and reset operations. Small seconds run continuously at six o’clock, independent of the chronograph mechanism.
