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 designation is recorded for this design yet.
No source in this corpus states which grade any Grand Seiko 9S66 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.
These figures belong to this caliber at this grade, and to nothing else. The same grade name on another caliber from the same maker carries different numbers.

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

grain 7 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.
