Cosmograph Daytona 16523 - Zenith Inverted 6 Champagne Dial - Watch Only (1990)

An early Zenith-powered two-tone Cosmograph Daytona from the E-serial generation, this 16523 wears the sought-after champagne dial with black contrasting sub-registers, small sub-dials and the collectible "Inverted 6" configuration. Powered by Rolex's Zenith-based Caliber 4030 and finished with a period-correct P6 clasp code, it captures the transitional Daytona era before the in-house 4130 arrived.
