You won't find a better Chromalight! In 'brand new old stock' factory condition, (never worn or polished) this black dial steel Daytona represents the ultimate stage of Rolex's development of the iconic 116520 Cosmograph. These rare 'perfected' models were in production for less than 2 years before production shifted to the Cerachrom bezel version in 2016 and are identified by the characteristic blue glowing Chromalight luminous hands and markers that were introduced to the Daytona sometime in 2014. Prestigous 'Rolex London' stamp on the cerrtificate, original box, both swing tags and Daytona bezel protector.
