Squale

Identity and scope

Squale is a Swiss-Italian dive-watch brand associated with the von Büren family.

This guide treats that identity as the starting point. It does not transfer line-level history to an individual watch without matching reference evidence. 1

Historical position

The official history dates Charles von Büren's work making watch cases to 1946 and the Squale shark trademark to 1959.

The date and context belong to the event described, not automatically to every object bearing the name. 1

What the source establishes

The cited Squale record is the evidence anchor used here for Squale. Its documented scope is narrower than a complete corporate, calibre, or model archive.

Where the source speaks for the brand, its historical statements remain attributed rather than converted into independent verification. 1

Identify the exact watch

Record every visible dial signature, the complete case-back reference and serial markings, movement or module markings, dimensions, materials, and complications. Compare those details with a dated catalogue, manual, archive extract, or service document for the exact reference.

A shared logo or broadly similar case is an identification lead, not proof of age, originality, or authenticity. 1

Keep entities and dates separate

Use 1946 only in the documented context described above. Names may survive ownership changes, disappear and return, or refer to a founder, historic maker, product line, and present operator at different times.

Build an object-level chronology before making continuity claims. 1

Research a Squale watch

Start with clear photographs of the dial, case back, crown, clasp, and movement where safely accessible. Search the exact markings in primary documentation and retain the document date and page or section.

For authentication, servicing, or valuation, use a qualified specialist and preserve provenance, invoices, and prior service records. 1

Independent research update

Squale is a Swiss-Italian dive-watch brand whose history is tied to Charles von Büren and specialist dive-watch case production.

Both brand and specialist histories connect the Squale name to mid-century von Büren activity, though they differ on whether the precursor start date is 1946 or 1948.

Independent specialist history reports later control by the Maggi family, Squale's longtime Italian distributor; current legal ownership was not registry-verified here.

Historical case making is well documented; current assembly and supplier structure should be verified by reference rather than inferred from the historic manufacture. 23
