Benrus DS1D (AS 1475)
bounding evidence — no range is drawn on the era axis
not after 1970

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.
