Family tree · none recorded
No lineage link to any other caliber is recorded for this design under the Heritage profile. That is a gap in the research, not a claim that none exists.

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.
