The Rolex Cosmograph Daytona ref. 116520 keeps things straightforward: black dial, 40mm stainless steel case, and matching bracelet. The tachymeter bezel gives it the racing link the model is known for without making the watch feel busy. Inside is an automatic chronograph movement, which is exactly what buyers look for in a Daytona. At 12mm thick, it has the compact proportions that set this reference apart.
