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 Rolex 3075 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.

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.
- Rolex 3085successor of
Recorded as commercial succession only, and even that with a caveat the source supplies: the 3085 launched ALONGSIDE the 3075 in 1982 rather than after it, and the GMT-Master line ran on until ref. 16700 was phased out in 1999. No source consulted states that the 3085 derives from the 3075, so no lineage edge is authored.
