Oyster Perpetual Cosmograph Daytona 40mm 16523

The Rolex Cosmograph Daytona Ref. 16523 embodies the spirit of high-performance motorsport—perfectly merging precise chronograph functionality with timeless aesthetics. Introduced in the late 1980s, the 16523 was the first “Zenith” Daytona to feature an automatic movement and marked a pivotal milestone as the first Daytona to combine Rolesor materials (stainless steel and 18k yellow gold) in a single model—something unprecedented at the time.

Its classic 40 mm dial design is complemented by a scratch-resistant sapphire crystal and an 18k yellow-gold tachymeter bezel, enabling highly accurate speed measurement—an essential tool for racing enthusiasts. The chronograph sub-dials at 3, 6, and 9 o’clock deliver a balanced, symmetrical layout infused with technical character.
