Identity

A caliber is three separate things and this reference keeps them apart: the construction, the names it is sold under, and the article a brand actually bought. A watch model points at an execution — never at a bare construction — which is why “same caliber” is almost never a complete answer.

No source in this corpus states which grade any ETA 2892-A2 was bought at. That unknown is stored as a real row rather than left blank, so it can be counted, filtered and excluded from any comparison that would otherwise assume parity.

no source states which grade this article was bought at — this row exists so 'unknown' stays countable instead of becoming an assumption

Lineage

The same relationships as the tree at the top of this page, with their sources. An absence in a column means no source stated one.

None recorded. An absence here means no source stated one, not that none exists.

Descendants · 19

What came from it — revisions, variants, clones, licensed copies.

grain 8 model · 99 reference — the count above mixes levels. A family record is one the source states a movement for family-wide; a reference record is one case reference. They are not the same unit and are never summed silently.

Every brand here is on the strength of a source that names a watch and states this movement. Brands that use this caliber and nobody has sourced yet are absent — this is what has been researched, not what exists.
