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.

| Caliber | Relationship | To | Status | Detail | Sources |
|---|---|---|---|---|---|
| Omega 8508 | derived from lineage | Omega 8500 | accepted | interchange note: the source lists the 8508 as one of the movements based on the 8500 series, differentiated by the antimagnetic material set rather than by architecture · component delta: balance_spring,pallet_fork,escape_wheel_treatment | |
| Omega 8900 | derived from lineage | Omega 8500 | accepted | interchange note: the source lists the 8900/1 among the movements based on the 8500 series, distinguished by METAS Master Chronometer certification · component delta: balance_spring,regulation_method,certification | |
| Omega 8500 | successor of related | design:omega-2500 | accepted | succeeds the 2500 in the lineup; the source explicitly denies derivation | |
| Omega 8500 | no derivation between related | design:eta-2892-a2 | accepted | — |
