Bracelet

PRX integrated bracelet

Probable

A bracelet that is structurally part of the case rather than attached to it: no spring bars, no conventional lugs, and a first link machined to meet the case with no visible gap. It is the most expensive part of the watch to make correctly and therefore the most informative part to examine.

  • Correct integrated join

    FactoryProbable

    Whole production

    No perceptible gap at the case join, no lateral play, and articulation that is even from link to link. The bracelet cannot be levered away from the case because there is nothing to lever against.

  • Concealed conventional lug

    CounterfeitProbable

    Whole production

    A counterfeit built on a standard lugged case with a cosmetic cover at the join. Detectable as a visible step, a rattle, or the ability to move the bracelet relative to the case. Conclusive when found.

  • Stretched period bracelet on a 1978 Seastar PRX

    PeriodProbable

    1978 →

    Forty-year-old integrated bracelets stretch at the pins and cannot readily be replaced, because the bracelet is specific to the case. Stretch is expected wear on a period example; a period PRX with a tight, unworn bracelet has been rebuilt or re-fitted.

    Whole production

    Examine the case join before anything else. It is the hardest part of the watch to counterfeit and the cheapest to inspect.

  • Tissot Seastar PRX (1978)Period

    1978 →

    Stretch is expected. A tight period bracelet needs explaining.
