Edge types in this family
accepteddisputedcontested region
Generations run left to right, ancestors first, and the axis along the top is ordinal rather than linear: each band is one generation, labelled with the range of sourced introduction years it contains. A band reads “—” when no caliber in it has a year anyone published — the gap is the finding, not a rendering failure. Dotted arcs above and below the drawing are related edges — successor, drop-in, no-derivation — which are stored in a different table from lineage and can never form part of an ancestry path.

| design:ap-7121 | successor of related | Audemars Piguet 2121 | accepted | the source calls the 7121 brand new and in-house-developed, and lists its differences from the 2121 as improvements rather than as a derivation. Commercial succession only — this row lives in related_edge and can never be walked into the JLC 920 ancestry. |
