Reference sources reviewed 7 November 2026. Published specifications, not independent measurements. Versions and complete-watch specifications can differ; fields without a verified figure are omitted or identified.

What distinguishes it

Look beyond the reference.

Its second time reference is read from the additional hand against a 24-hour scale. Quick correction acts on that hand rather than giving the local-hour jump associated with a traveller GMT.

For the enthusiast

Compare it with the SW330-2 for another slim GMT architecture, or with the Miyota 9075 for different crown operation. ETA’s current portal lists a typical 50-hour reserve; use the specification of a particular watch when identifying an older execution.
