For sale at Debonar Watches: pre-owned Rolex Daytona 116520. This amazing Rolex watch sports a black dial.When the Ref 116520 launched in 2000, it was kind of a big deal for Rolex. It replaced the outgoing Ref 16520, better known as the Zenith Daytona.And it debuted the brand’s first ever, in-house self-winding chronograph. The Calibre 4130. Considered one of the best mass-produced chronograph movements ever.Comprised of 290 parts – far fewer than your standard chronograph movement at the time – Calibre 4130 set a high bar. Reducing the number of components made the movement easier to service. And more reliable. But it also freed up space, allowing Rolex to incorporate a larger mainspring. This increased the power reserve on the Ref 116520 to 72 hours (compared to 54 hours on the Zenith Daytona). All whilst still delivering timekeeping accuracy of -2/+2 seconds per day.The Daytona is a legendary model of the most iconic luxury watch maker company and it’s been continuously evolving for almost 50 years.It’s virtually indestructible “Oyster” case makes it a watch that can be enjoyed through generations.It is also a very cool looking and versatile watch which can match practically every kind of style.
