For sale at Debonar Watches: pre-owned Rolex Daytona 116500LN, full set. The reference 116500LN is, as they say, one unit of pure Daytona: 904L Oystersteel case, 40mm x 12.2mm, with screw-down crowns, Cerachrom bezel, matching 904L Oystersteel bracelet.In terms of the tachymeter markings on the bezel, for the 116500LN (and other modern Daytona models) we have a units-per-hour engraving at 1:00, with a measurement range from 400 to 60.On the Cerachrom bezel, the tick marks from 100 to 60 are also connected with an underline and this element, plus the triangular markers and crisp depth of the numerals and markings, gives the 116500LN a very modern and slightly high-tech feel.The weight of the watch is not insignificant but it's pretty evenly distributed around the wrist.Its story starts all the way back to the year 1963, when the first Cosmograph chronograph was introduced. The first Cosmograph, the ref. 6239, wasn't a hit straight out of the gate for Rolex – in fact, it sold sluggishly at first.However, in the 59 years between the launch of the first reference and today, the watch has undergone a tremendous technical evolution as well, making the new version of the Daytona the most advanced chronograph Rolex has ever produced – by a considerable margin.
