Rolex Daytona Cosmograph 116523 Mens Watch. 
The Rolex 116523 Daytona relies on the calibre 4130 Perpetual movement - the very first in-house chronograph movement. It boasts every modern amenity available to the Rolex catalog, including a Paramagnetic blue Parachrom hairspring, 70-hour power reserve, and accuracy up to -2/+2 seconds per day. It is singularly reliable and is prepared to keep perfect time, on or off the racetrack. Reference 116523 is a Yellow Rolesor Daytona featuring Oystersteel and 18k yellow gold. It's luxurious while maintaining the sporty aesthetic that has accompanied the Daytona collection for decades. The example you see here also features a handsome black dial decorated with Superluminova plots. This Rolex has since been discontinued and is a very prized collector's item.
