Authentication

The Urban Jurgensen 1140 is a manual-wind dress watch with enamel or guilloché dial and Roman numeral hour markers. It carries the same high finishing standard as the rest of the UJ line. Authentication concerns are the same as the P8: condition misrepresentation and provenance verification.

Known issues in the market
  • Enamel dials on genuine 1140 examples are visually distinctive: depth, color saturation, and translucency not achievable by printing.
  • Roman numeral printing quality on genuine dials is precise; any variation in stroke weight or spacing under magnification is a concern.
  • The 1140 is small production; any example should have a documented transaction history.
