Pre-owned Rolex Cosmograph Daytona 116520 watches hold serious historical weight as the brand's first chronograph featuring an entirely in-house movement. Manufactured from 2000 until 2016, this 40mm stainless steel legend debuted the Caliber 4130, massively improving reliability and pushing the power reserve to 72 hours. Unlike current versions, it sports a polished steel tachymeter bezel instead of ceramic, giving it a bright, cohesive metallic look. Available strictly with black or white dials, this reference attracts motorsport fans and serious collectors chasing the raw, classic steel styling of early-2000s Rolex sports models.
