Identity and scope

Sjöö Sandström is an independent Swedish watch company based in Stockholm.

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 story dates the company, founded by engineers Christer Sjöö and Mikael Sandström, to 1986 and its first Automatic model to 1993.

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

What the source establishes

The cited Sjöö Sandström record is the evidence anchor used here for Sjöö Sandström. 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 1986 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 Sjöö Sandström 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
