Editorial
The Monaco Calibre Heuer 02 is the square chronograph that stopped needing apologies. TAG Heuer finally fitted its own column-wheel flyback movement inside the case in 2019, and the watch earned its price tag for the first time in years.
Jack Heuer and designer Jorg Hysek launched the original Monaco in 1969 as one of the first automatic chronographs, and Steve McQueen wore the ref 1133B on screen in Le Mans two years later. That association made the square blue dial a cultural fixture before most buyers were born. For decades after Heuer became TAG Heuer, the Monaco survived on the strength of that story while running Valjoux and later Sellita-based calibers that critics rightly found hard to justify at the price.
The Calibre Heuer 02, introduced across the Monaco line starting in 2019, replaced the outsourced base with an in-house column-wheel vertical-clutch flyback movement developed entirely by TAG Heuer. The CBL2111.FC6453 in dark blue carries that movement in the original 39mm steel square case with its left-side crown, the configuration unchanged in geometry from the original.
The square case measures 39mm corner to corner but wears larger than that number implies; buyers coming from round watches are frequently surprised by how much wrist presence it commands. Crown placement on the left side is deliberate and historically correct, but it is genuinely awkward to set if you are accustomed to right-side crowns. The blue textile strap on the CBL2111.FC6453 ages and shows wear faster than leather or bracelet alternatives; budget for a replacement strap sooner than you might expect.
Earlier Monaco references running the Calibre 11 (Sellita SW300 base) retail for considerably less and look nearly identical to untrained eyes, so confirm the movement designation before purchasing any Monaco described as "recent." Water resistance is 100m, which is adequate for daily wear but the square case geometry and the crown placement make accidental water exposure a higher risk than with conventional case designs.
