Authenticate TAG Heuer Monaco
The square case with the crown on the left, which counterfeits routinely put on the right.
Introduced 1969La Chaux-de-Fonds
The Monaco's original design places the crown on the left side of the case, because the movement it was built around dictated it. Many later references moved it, so crown position is a reference question rather than a universal rule — but a watch presented as a 1969-style Monaco with a right-hand crown is being misdescribed.
The case is square with a specific relationship between its brushed top and polished flanks, and its water resistance comes from a gasket arrangement that counterfeits do not reproduce. The crystal is domed on heritage references.
Subdial placement and the chronograph's reset behaviour are the mechanical reads, as on any chronograph.
What a Monaco does on the secondary market
The maison's strongest heritage market, driven by the model's film association. Original-dial vintage pieces command real premiums.
An orientation for honest, unrestored condition — never an appraisal, and never a quotation.
