Yema

Identity and scope

Yema is a French watch brand based in Morteau.

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 watchmaker Henry Louis Belmont's founding of Yema to 1948 and documents its French sport-watch heritage.

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

What the source establishes

The cited Yema record is the evidence anchor used here for Yema. 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 1948 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 Yema 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

Yema identifies an independent French watchmaker based in Morteau, founded by Henry-Louis Belmont in 1948.

The brand's own chronology separates Belmont, Matra/Richard Mille, Hattori-Seiko and Ambre France periods, so continuity should be described through ownership eras.

Yema states that design, prototyping, manufacturing and assembly occur in Morteau, while current pages also qualify which caliber components are made in-house.

Yema's current history says the Bôle family manages the company and records Ambre France from 2009 to date. 234
