Bracelet

Nautilus integrated tapering bracelet

Probable

An integrated bracelet designed as part of the case rather than attached to it, tapering toward the clasp, with each link carrying the same brushed-top and polished-chamfer treatment as the bezel. Articulation is close and even, and the bracelet should drape as a continuous curve rather than hanging in segments.

  • Stretched bracelet

    FactoryProbable

    Whole production

    Wear at the link pins produces play that reads as looseness. Normal on a watch of age, a condition observation rather than a finding — and it removes tightness as a check, which is worth recording.

  • Replacement bracelet fitted at service

    ServiceProbable

    Whole production

    Patek supplies replacement bracelets. Correct, and an originality observation on a watch where the bracelet is a substantial part of the value.
