Dial

Fumé gradient dial

Probable

Moser's signature dial: a lacquer gradient running evenly and concentrically from a bright centre to a near-black periphery, with no visible step, band or transition line. Difficult to execute consistently, and on the Concept watches — which carry no printing whatever — it is the ONLY dial evidence there is.

  • Even, concentric, unstepped gradient

    FactoryProbable

    Whole production

    The gradient is centred on the dial, grades continuously with no visible banding, and stays even as the watch is rotated under diffuse light. That last point is the practical test: an uneven gradient reveals itself as the light moves across it, where a static photograph can conceal it.

  • Stepped, blotchy or off-centre gradient

    CounterfeitProbable

    Whole production

    Copies show banding where lacquer was built up in discrete passes, pooling where it was applied unevenly, or a gradient whose bright centre sits off the dial's axis. Since a Concept dial has nothing else printed on it, this is the whole dial check and it carries correspondingly more weight than a single dial observation usually would.

Photographic reference for fumé gradient quality

How does a genuine Moser fumé gradient behave under rotation and varied lighting, compared with the copies now in circulation?

Scope An unusual case where still photography is inadequate to the gap: the check depends on how the gradient behaves as light moves across it, so the reference material needed is video rather than images. Worth noting because it also implies the right instruction to a remote seller — ask for a rotating video, not more photographs.
