ETA SA Manufacture Horlogère Suisse

A cluster profile is a rule for what counts as descent, not an opinion about it. These are the lines this maker’s designs sit in under the site’s other rules — a broader one keeps edge types that the Heritage sense does not traverse, so the same root can appear here with more members. Nothing below is a relationship the corpus does not hold; it is the same claims read under a different filter, and each view says on its own page which edge types it traversed.
