The Daytona 16520 reverse 6 single buckle has become particularly hard to find recently. The dial is Mark 4. And the bezel is also Mark 4. This is a good Rolex with a clean look that has been overhauled (last in 2016).
The serial number is N and it is believed to have been made in 1991.

As you can see from the picture, the needle was replaced during the overhaul. However, we have the original needle, so you can choose to either return it to the original or keep it as a spare.

With the current model 116500LN increasing in price, it would be wise to stick with something like the 16520 Zenith movement, inverted 6, single buckle.
Please take this opportunity.
