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 |
|---|---|---|---|---|---|
| Breguet 502.3.QSE1 | variant of lineage | Breguet 502.3 | accepted | interchange note: the edge rests on Breguet's own calibre numbering — 502.3.QSE1 is the 502.3 root plus a suffix — corroborated by identical power reserve (45 h) and frequency (3 Hz) with a larger component count (236 vs 162) and greater height (3.8 vs 2.4 mm). No source read states the derivation in words, so the basis is recorded here rather than implied. · component delta: calendar_mechanism,complication_module,dimensions |
