Manufacturer
Valjoux SA
Attribution is time-dependent in this model: a design keeps its identity when a company is absorbed, and only the maker record moves. Every row of the designs table below carries the source for its own attribution.
Family lines
40 designs are attributed to Valjoux SA. 16 of them sit in 14 recorded family lines under the Heritage sense of the word — the 3 largest are drawn below, the rest listed under them. The other 24 stand alone in this sense, and no other sense of “family” puts them in one either: this corpus records no relative for them — not that none exists.

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.

Corporate history
These edges move ownership and names, never designs. This is why “who made the 7750 in 1978” and “who makes it now” are different questions with different answers about the same construction.

The export gives these edges a claim id but no inline reference, so the claim id is shown as the citation anchor rather than a source link.
