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.
Study this alongside the SW200-1: similar basic dimensions and frequency make their different executions especially worth examining.
For the enthusiast
ETA’s current portal gives a typical 42-hour reserve. Historical documents and individual watch references may specify different figures; identify the execution rather than relying on the family name alone.
