Case

Articulated floating lugs

High confidence

Lugs that pivot relative to the case body so the watch conforms to the wrist. A moving mechanical assembly with bearings and tolerances, not a case shape — which is what makes it the fastest and most decisive physical check on the brand.

  • Lugs that articulate smoothly

    FactoryProbable

    Whole production

    The lugs pivot with controlled resistance and no play, returning the watch to the wrist's contour. Move them: the mechanism either works or it does not.

  • Fixed lugs shaped to suggest articulation

    CounterfeitProbable

    Whole production

    The copy's economy. Reproducing the appearance of a pivot is cheap; reproducing a working pivot with correct tolerances is not. Lugs that look articulated and do not move are conclusive.

  • Worn or loose pivots on a used example

    FactoryProbable

    Whole production

    A moving assembly wears. Excessive play in the lugs of a genuine watch is a condition and service finding rather than an authenticity one — the presence of a functioning mechanism is the check, not its tightness.

  • Whole production

    Move them. This is the fastest decisive check on the brand.
