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.

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.
