The ref. 16528 has a mechanical automatic self-winding Zenith El Primero caliber 4030 (Zenith base 400) movement. It's rhodium-plated, with oeil-de-perdrix embellishment. It's constructed with 31 jewels, a blue Parachrom hairspring, an Incabloc shock absorber device, and a straight-line lever escapement. It includes a monometallic balance that's adjusted to temperatures and 5 positions, a self-compensating free-sprung Breguet balance spring, and Microstella regulating screws.
This mechanism oscillates at a frequency of 28,800 vph (4 Hz).
Introduced in 1963 as a sports companion for professional race car drivers, the Daytona comes equipped with a Tachymeter bezel that can be used alongside the sub-dials to calculate speeds of up to 400 kilometers per hour.
