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.
Every edge in this view
| Caliber | Relationship | To | Status | Detail | Sources |
|---|---|---|---|---|---|
| Rolex 4130 | successor of related | design:rolex-4030 | accepted | Commercial replacement, NOT descent. Sources describe the 4130 as Rolex's FIRST in-house chronograph and compare it to the 4030 only by contrast — fewer parts, vertical instead of horizontal clutch, longer reserve, sub-dial order changed. No source consulted asserts that the 4130 derives from the 4030 or from the Zenith El Primero, and no lineage edge is authored here. |
