Authenticity & Servicing

What a vintage watch should look like, how to spot problems, and how to keep a mechanical movement healthy.

What “original” means

An original vintage watch has the dial, hands, case, crown, crystal and movement that were appropriate for its production period. Perfectly original watches are rare after decades of use. Collectors usually accept routine service parts, but replaced dials or hands can change both appearance and value.

Dials

  • Redialling means repainting or replacing a dial. Look for printing that is too sharp, fonts that differ from known originals or uneven lettering.
  • Patina is natural aging, such as warm cream tones or small spots. Some buyers value it, but it should look consistent across the whole dial.

Hands and luminous material

Mid-century watches used radium-based luminous paint, which was replaced by tritium during the 1960s, and later by non-radioactive materials. Hands and dial markers should have matching lume tone. Mismatched colours often indicate a replacement. Radium and tritium watches should be stored and handled sensibly; consult a qualified watchmaker if you have concerns.

Cases

Repeated polishing softens sharp edges and thins hallmarks. Compare case shape with reference photographs, and look for crisp bevels on the lugs. Check the case back and inside for engravings and serial numbers consistent with the reference.

“Franken” watches

A “franken” watch combines parts from different watches. It may keep time perfectly well but be worth less than an original example. The best protection is a seller who shows high-resolution photographs, movement images and documentation, and who offers a return period.

Servicing

  • Mechanical watches are commonly serviced every 5–10 years, depending on maker recommendations, usage and how the watch runs.
  • Choose a watchmaker experienced with vintage calibres and ask whether they can source or fabricate parts.
  • Request that replaced parts are returned to you. This helps document what changed.
  • Do not assume an old watch is water resistant. Gaskets age, so treat it as splash-resistant at best until a watchmaker has tested it.
