Minerva arrow-shaped chronograph bridge

Probable

The arrow-shaped chronograph bridge that has been Minerva's visual signature since its 1920s chronograph calibers, sometimes called the devil's tail. Recorded as a component because it is the single most reliable identifier of a Villeret movement, and because it is visible through the display back these references always carry.

    The arrow form with hand-applied bevelling: bevel width varying slightly along its length and internal angles brought to a crisp point. Nothing in Montblanc's volume production carries this bridge and no generic movement does either.

  • Absent on a watch presented as Villeret Minerva

    CounterfeitProbable

    Whole production

    Conclusive. A Villeret piece without a Minerva caliber behind its display back is not a Villeret piece, whatever the dial, the box or the paperwork say. This is the strongest single check on the brand.
