The Rolex Daytona reference 16520 is a famous chronograph among watch fans. It has a solid 40mm stainless steel case. This model uses a modified Zenith El Primero movement, reworked heavily into the Rolex Caliber 4030. Its white dial shows contrasting black rings on the three sub-dials. Instead of hour numerals, you get simple applied markers. The fixed steel bezel holds an engraved tachymeter scale to track speed. This piece is in like-new condition and comes as a watch-only set. But we give you a limited one-year warranty for your peace of mind.
The watch sits on a stainless steel Oyster bracelet. Inside, the automatic movement beats at 28,800 vibrations per hour. Rolex actually lowered this beat rate from the original Zenith base to reduce parts wear. You can easily spot the screw-down pushers on the right side. They block water and dust from reaching the caliber. The 16520 has a slightly slimmer case profile than modern Daytonas. It fits comfortably on men, acting as a reliable daily watch with real mechanical history.
