Davosa
Davosa is a Swiss watch brand whose model families include Ternos and Argonautic. Its own history relates its background to watchmaking within the Hasler family. The family, earlier companies and the Davosa brand should not be treated as one unchanged business throughout that history.
What does DAV mean on a movement?
The manufacturer states that DAV calibres are produced in Switzerland by movement makers such as ETA, Sellita and Soprod. The DAV designation alone therefore does not establish a movement made entirely from scratch by Davosa. Check the specific calibre number. The brand's own overview lists several calibres with different functions and power reserves.
Identifying a pre-owned example
Record the complete model name, reference, calibre and case-back information. Compare the correct size and variant with documentation from the relevant period. A name such as Ternos can cover different versions, so a single specification sheet does not automatically describe the entire family. Note service history and replacement parts. Original water-resistance specifications are not a condition report for the watch today. Assess secondary-market value through the particular example's execution, condition and documentation.
