Authentication guide

Last reviewed June 2026

The Classics Index Automatic is FC's accessible three-hand dress watch; clean dial, applied indices, and the FC-303 manufacture movement are the authentication anchors.

Known reproduction risks

LOW

Not a reproduction target; value proposition is the brand and movement, not a trophy reference.

Hands

Original: Leaf-style or baton hands in polished steel; luminous fill.

Replacement tells

  • Mismatched lume color between hands and indices (green vs. blue-white) suggests mixed parts.
Case

Original: Polished bezel with brushed case flanks; no engraving.

Replacement tells
  • Fully polished case indicates refinishing; the brushed flanks are part of the original finishing spec.
