A stated 1790 heritage
The current Cortébert site presents the brand as Swiss watchmaking heritage since 1790. Maison Tellus's related history says Adam-Louis Juillard founded a watchmaking business in Sonvilier in 1790.
This origin context should not automatically date a specific Cortébert-marked object. 12
Factory identity evolved over time
Maison Tellus describes an ébauches factory in Cortébert inaugurated in 1865 and renamed Fabrique d'ébauches de Cortébert in 1880. It presents these as stages in a longer family and industrial story.
The business name, dial name and movement provenance can therefore be distinct research questions. 2
Current brand claims need model-level limits
The present Cortébert site describes historical pilot, railway and ocean-carrier watches alongside an in-house-movement identity. Such positioning is useful context but is not a technical sheet for each vintage watch.
Verify calibre and reference details from period evidence. 1
Movement supply is a separate attribution
Cortébert's current site states that it supplied movements to brands including Rolex and Panerai. Treat this as a high-level historical claim that requires a named calibre and watch context before it is applied to any individual object.
A dial signature alone does not prove who made every component. 1
Tellus documents later separation
Maison Tellus says the Cortébert group took over Tellus in 1942, that the Juillard family sold its Cortébert Watch Co stake in 1962, and that Tellus left the Cortébert group in 1993. These events show why continuity claims need precise dates and entities.
Do not merge a Tellus watch and a Cortébert watch into one undiscriminating history. 2
Keep conclusions source-bounded
Current Cortébert and Tellus sources support a stated 1790 heritage, factory-development context and later organizational changes. They do not authenticate a vintage watch or establish its value.
Use movement, case, dial and reference evidence for consequential conclusions. 12
Key dates
Ownership and continuity
Official current and related-brand sources place Cortébert in a long Swiss watchmaking story while documenting important factory and ownership changes that must not be collapsed into one uninterrupted product narrative. 12
Watchmakers and designers linked to Cortébert
These people have a sourced relationship to this brand in the Enjoy Watches register. The label beside each name states the relationship recorded; it should not be read as a broader employment or ownership claim.

Identification and service
For an individual watch, record the complete reference, serial, dial, case, and movement markings and compare them with dated primary documentation.
A brand history cannot authenticate, appraise, or establish the provenance of a particular watch.
