This watch is a chronograph which means it tracks time, like a stop watch. What makes it unique is its tachometer. That's why they call it a driver's watch.
The bezel helps you measure the elapsed time over a pre-determined distance. You can measure up to 400 units per hour whether measured in kilometers or miles.
It's got a nice heavy feel to it and a look that from a distance is similar to a sub-mariner.
However, if you are more likely to be driving a sports-car than looking at fish, it's probably a better choice.
The Rolex Cosmograph Daytona that we have is in like new condition. It's got a two tone yellow gold and brushed steel Rolex oyster bracelet.
