Built around a 40mm 18k yellow gold case, the Daytona 16518 presents a white dial with black printed minute markers and three black subsidiary registers tracking elapsed hours, minutes, and constant seconds. The 18k yellow gold bezel carries an engraved tachymeter scale, rounding out the Daytona's enduring profile. A sapphire crystal protects the dial, while the solid case back and screw-in crown deliver water resistance to 100 meters / 330 feet.
At the heart of the 16518 sits the Caliber 4030, a manual-winding chronograph movement based on the Zenith platform and modified by Rolex to operate at 28,800 vph, featuring a Glucydur balance wheel and KIF shock protection. The movement delivers a power reserve of approximately 50 hours, a hallmark of the Zenith-era Daytona that collectors continue to hold in high regard.
The watch is worn on a brown alligator leather strap secured by an 18k yellow gold deployant clasp. This example is accompanied by the original Rolex box and store warranty papers, making it a well-documented piece from one of the most celebrated periods in Daytona production.
