Identity and scope

Steeldive is a Chinese watch brand focused on mechanical dive and sport watches.

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 storefront establishes the active brand and current catalogue; company and model chronology should be drawn from dated product and business records.

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

What the source establishes

The cited Steeldive record is the evidence anchor used here for Steeldive. 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

No specific date is established by this guide. Use only 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 Steeldive 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

Steeldive is a Chinese dive-watch brand that states it was established in Guangzhou in 2008.

The brand's 2008 origin is repeated by an independent watch-review source, but deeper company chronology remains thin.

U.S. trademark records identify Cheng Tianbao as owner of the STEELDIVE mark for wristwatches and related goods; the broader Chinese corporate structure was not independently established. 234

Ownership and continuity

The current evidence identifies Steeldive and establishes the bounded historical context above; an individual watch still needs reference-level documentation. 1

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.
