The Cosmograph Daytona reference 116500LN represents a significant evolution within the Daytona collection, introducing a black Cerachrom bezel to the steel model. This reference succeeded the 116520 and quickly became a highly sought-after contemporary chronograph. It maintains the classic Daytona aesthetic while incorporating modern material technology for enhanced durability and scratch resistance on the bezel. This reference features a 40 mm Oyster case crafted from Oystersteel, paired with a fixed black Cerachrom bezel with an engraved tachymetric scale. It is powered by the in-house Rolex Caliber 4130, a self-winding mechanical chronograph movement known for its robust construction and precision. The movement offers a power reserve of approximately 72 hours and is protected by a scratch-resistant sapphire crystal, ensuring water resistance up to 100 meters. Appealing to collectors interested in modern Rolex chronographs, the 116500LN is available with either a white or black dial, both offering high contrast against the black bezel. Its combination of traditional steel construction with advanced ceramic technology positions it as a key reference in the ongoing development of the Cosmograph Daytona line, bridging classic design with contemporary material science.
