This Aquaracer CAY2110.BA0927 features a 43mm stainless steel case with 300 meters of water resistance. The model retains the previous generation's dodecagonal bezel and integrated rider tabs, originally designed to provide grip underwater.
Beneath the sapphire crystal, a horizontally striated black dial organizes a 12-6-9 chronograph layout, accented by a yellow-tipped central seconds hand. Driven by the automatic Calibre 16 movement, this specific unit has been preserved in an unworn state with its factory protective plastics intact since 2019.
From its founding in 1860, Heuer established a reputation for precision built on foundational innovations. Edouard Heuer's 1887 patent for the oscillating pinion remains a critical component in modern chronographs, while the 1916 "Mikrograph," the first stopwatch capable of measuring 1/100th of a second, secured the brand's role as an official Olympic timekeeper. This early focus on accuracy naturally led to a deep-seated connection with motorsports, where the brand's dashboard timers became essential equipment for rally drivers, laying the groundwork for an identity forged on the racetrack.
The brand's ties with racing was immortalized in the 1960s with a trio of legendary chronographs: the Carrera, Autavia, and the avant-garde Monaco. The Monaco, with its distinctive square case, became an icon on the wrist of Steve McQueen in the film Le Mans and was one of the first watches to house the groundbreaking Calibre 11 automatic chronograph movement. After its acquisition by Techniques d'Avant Garde (TAG) in 1985, the brand solidified its legendary status through a decades-long partnership with Formula 1.
