Tag Heuer released the Monza Caliber 36 Ref CR5110 in 2001, with several updates that included the use of a case shape similar to an early Heuer cushion-style case from the 1930s. The Monza timepiece line was initially released in 1976 to celebrate Niki Lauda’s third-place finish at the Italian Grand Prix at the Autodromo Nazionale di Monza, which secured his Formula 1 championship in 1975. The Heuer Monza Caliber 36 Ref CR5110 is fitted with the legendary El Primero movement, with its revolutionary 36,000 vibrations per hour and 50-hour power reserve.
