The Cosmograph Daytona reference 126503 in Oystersteel and yellow gold represents the accessible entry point into precious-metal Daytona territory. The two-tone configuration pairs a steel case body with an 18k yellow gold bezel and matching gold centre bracelet links, delivering the visual impact of gold at a lower price point than full-gold references.

The 126503 Up Close: Case, Dial and Bracelet
The fixed 18k yellow gold bezel carries the engraved tachymeter scale, framing a champagne gold dial that harmonises with the precious-metal accents. Three contrasting subdials provide the chronograph readouts, while applied gold hour markers and luminescent-fill hands ensure readability. The Cyclops-free crystal keeps the look purely sporting.
The two-tone Oyster bracelet alternates steel outer links with gold centre links, terminating in an Oysterclasp with Easylink micro-adjustment. Explore more two-tone and full-gold options in the Daytona collection.
Movement Options: Swiss vs Japanese
Two automatic chronograph movements are available for this reference:
- Swiss Automatic — elevated beat rate for a fluid chronograph seconds sweep, extended power reserve, and refined rotor finishing. The preferred tier for collectors.
- Japanese Automatic (Miyota) — robust 21,600 vph caliber with approximately 40-hour reserve. Easy to service globally and suited to everyday chronograph duties.
Both offer automatic winding and hacking seconds functionality.
