When identifying a Tudor watch, the reference and serial numbers are typically the most important starting points. The reference number identifies the specific model and can be verified against Tudor's known catalog. Genuine Tudor watches display consistent, well-executed engravings between the lugs, and the font and depth of engraving are elements collectors often examine. The Tudor shield logo on the dial and case should match the style appropriate for the production era.
Movement inspection is another commonly recommended step. Vintage Tudor watches typically contain third-party movements from ETA or its predecessors, often modified to Tudor specifications with Tudor-specific rotor engravings. Modern Tudor watches with in-house MT5xxx calibers (such as the MT5602, MT5612, or MT5813) feature distinctive architecture recognizable to qualified watchmakers. The movement should be consistent with the model reference and era.
Dial authenticity is an area of particular scrutiny, as dials significantly impact a vintage Tudor's value. Genuine dials typically feature precise printing, correct font styles for the era, and appropriate lume application. Key details include the rose or shield logo rendering and the aging of luminous material. Given Tudor's historical relationship with Rolex, some vintage components may bear Rolex markings, which is generally expected. For significant purchases, professional authentication by a Tudor specialist is commonly recommended.
