This profile traverses clone_of · derived_from · design_imitation_of · ebauche_of · incorporates_module · licensed_copy_of · module_on · revision_of · tooling_transfer_of · variant_of and keeps disputed edges. Every edge in this view carries at least one reference.
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.

| Caliber | Relationship | To | Status | Detail | Sources |
|---|---|---|---|---|---|
| Audemars Piguet 7138 | derived from lineage | Audemars Piguet 7121 | accepted | interchange note: the SAME source also derives the calendar itself from the 5133. Only one lineage parent is asserted (the base), because two lineage edges of different types between overlapping pairs would read as conflicting topology; the 5133 debt is recorded here in the qualifier and in this design's summary rather than smoothed away. · component delta: calendar_mechanism,keyless_works | |
| Audemars Piguet 7121 | successor of related | design:ap-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. |
