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.
The shallow 3.60 mm movement gives it a different packaging role from ETA’s taller 2824-2. For an enthusiast, it is a useful starting point for understanding the architecture behind many slim Swiss automatics.
For the enthusiast
ETA writes the reference as 2892A2 in its portal. The 50-hour reserve shown here is the portal’s current typical figure; an older watch or brand-specific derivative can differ. The name alone does not establish the finished watch’s regulation, decoration or certification.
