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.

| Bulgari BVF 900 | derived from lineage | Bulgari BVL 180 | accepted | interchange note: A tourbillon regulator is added, and the hours and minutes displays are merged at 2 o'clock, replacing the BVL 180's separated regulator-style dials. The display change is not a component on the DE-1 list and is recorded here rather than invented as one. · component delta: complication_module |
