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 2834-2 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.

Where a property carries more than one value, the values have different scopes — an official spec sheet and observed hardware, say. Different scopes are not a disagreement, so both are accepted and both are shown with the scope they apply to.

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.

grain 49 reference — every record here sits at the same level, so the count is one kind of thing.

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.
