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 Rolex 1575 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.

Where a property carries more than one value, the values have different scopes — an official spec sheet and observed hardware, say. Different scopes are not a disagreement, so both are accepted and both are shown with the scope they apply to.

Commercial replacement. The sources contrast the 3035 with "the previous calibre 1575" on frequency and quick-set date but never state a derivation, so no lineage edge is authored.
- Rolex 3075successor of
Commercial replacement in the GMT-Master line: ref. 16750 (cal. 3075) replaced ref. 1675. The GMT article names only the reference ("19,600vph on the 1675 models"); the Submariner article supplies the calibre inside the 1675 (the 1575). The join between the two is recorded here rather than hidden.
