Dial

Dial signature: Heuer or TAG Heuer

Probable

The dial signature changed from Heuer to TAG Heuer when Techniques d'Avant Garde acquired the company in 1985, and the modern heritage reissues have revived the plain Heuer signature. The shield logo accompanies both in varying executions.

    Whole production

    Correct for anything made before 1985 and correct again on a modern heritage reissue. The signature therefore dates a DIAL and not a watch, and reasoning straight from it to a production year is the error the boundary invites.

  • TAG Heuer signature on a pre-1985 watch

    ServiceProbable

    Whole production

    An inconsistency requiring an explanation — most often a service dial fitted after the ownership change, which is a genuine part correctly fitted and an originality finding rather than an authenticity one. Establish the case and movement period first and read the dial against it.
