At 40mm wide, around 47mm lug-to-lug and just 12.2mm thick, the Rolex Daytona 116520 comes as a compact package. Most impressive is its thinness: at the moment I cannot think of another automatic chronograph with a vertical clutch that is as thin as the Daytona equipped with its 4130 caliber. This noted, it has to be said that the lack of a second timezone or a date indication helps shave off important millimeters, but even so, there are many non-chronograph watches out there these days that appear considerably chunkier on the wrist than the 116520... the Rolex Daytona 116520 is a true classic and one that will look good forever – and some more after that. Its overall wearability and functionality both as a luxury chronograph and a luxury accessory is solid, but its ubiquity and lack of easy-to-attain exciting features expose it to the competition now more than ever.
