About the reference
This page is deliberately an identification file. We need a legible caseback, movement identification and source-supported date range before publication as a verified reference.
Why it belongs in the archive
The archive should document the playful and inexpensive models, not just the famous milestones.
Identification notes
Demo design record. Decade filter is provisional and should not be interpreted as a production date.
Proper identification compares the reference, movement stamp, dial code, caseback or case construction, observed hands and dial, and period catalogs. Replacement parts and past service can create contradictions without establishing fraud or a precise production date.
Sources & research quality
We distinguish direct manufacturer or museum evidence from collector observations, dealer descriptions and anecdotal reports. Claims not yet supported are left visibly open.
- Further archival source verification is still pending.
