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.

|---|---|---|---|---|---|
| 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 |
