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.

The market

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.

Questions we are asked

Should the Monaco's crown be on the left?
On the original 1969 design, yes, because the movement dictated it. Later references moved it, so crown position is a reference question; but a watch presented as a 1969-style Monaco with a right-hand crown is being misdescribed.
Is the Monaco case square?
Yes, with a specific relationship between its brushed top and polished flanks, and a domed crystal on heritage references.
