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

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.

No source in this corpus states which grade any Omega 252 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.
