Vertex

British heritage watch company with four current regular-production families, Swiss Sellita movement routes and current first-party wording that conflicts over whether completed watches are made or hand-assembled in the UK or manufactured in Switzerland.

Editorial classification

The British Bench editorial classification

The British Bench records documented facts about where design, development, component manufacture, assembly, regulation, testing, quality control and related work take place, then applies its own editorial provenance methodology to those facts. A tier is an editorial classification only. It does not determine whether a watch, company or claim is legally British or British-made; assess compliance with origin, advertising or consumer-protection rules; certify or approve a product or maker; or measure quality, value, legitimacy or company nationality. A higher tier confers no legal status, certification, approval or endorsement. A lower tier does not mean a less-British company, a worse watch, misconduct or an improper or unlawful origin claim.

Documented factual findings

What happens within the qualifying territory

Published operations are shown here; the route cards identify how The British Bench interprets them for each physical tier.

No qualifying-territory operations are currently established in the published record.

Documented factual findings

What is made or completed elsewhere

Documented imported components and international specialist work remain visible beside domestic operations.

Movement manufactureDocumented — attributable published primary source

Swiss movement manufacture across the current mechanical range

Current Vertex mechanical movements are Swiss Sellita calibres, with family-specific customisation and certification where stated.

Switzerland

Watch assemblyDocumented — attributable published primary source

Swiss manufacture wording on current M100 and M36 families

Current M100 and M36 product pages explicitly state manufacture by Vertex’s atelier in Switzerland; the pages do not separately decompose manufacture and final assembly.

Switzerland

Timing measurementDocumented — attributable published primary source

M60 movement testing and COSC certification before completed-watch route

M60 movement-level Swiss testing and COSC certification are disclosed separately and do not establish the completed-watch post-casing control sequence required by Tier III.

Switzerland

Unknown and unresolved

What the available evidence does not establish

These fields remain Unknown rather than being converted into a negative fact, inferred location or assumed production route.

Design and developmentMaker/published claim — process not documented

Current model-specific product definition with design location unresolved

Vertex publishes substantial model-specific product definition across its current range, but the current sources do not establish the location and responsibility of the design/development process to Provenance Framework v0.2 Tier IV depth.

Unknown — Current design and development location not publicly established

Watch assemblyUnknown — sources conflict

Current UK workshop and M100 hand-assembly wording conflicts with Swiss manufacture wording

Vertex currently publishes both UK-workshop / M100 UK hand-assembly wording and Swiss-manufacture wording. The British Bench does not infer which final assembly stages occur in each country until the route is reconciled.

Unknown — United Kingdom and Switzerland — current first-party statements conflict

M36 Desert Edition limited run

Collection · Under review

Current and orderable

The British Bench’s editorial interpretation

Vertex identifies the M36 Desert Edition as a finite run of 30 numbered watches using the M36 route.
The limited run remains visible but is excluded from current regular-production maker-summary arithmetic under the v0.2 special-edition rule.

International work

The M36 route is publicly described as manufactured by Vertex’s atelier in Switzerland and uses a Swiss Sellita SW260-1 movement.

Evidence gaps

The same UK-versus-Switzerland assembly/manufacture conflict affecting the regular M36 route remains unresolved for this finite run.

Collection · Under review

Current and orderable

The British Bench’s editorial interpretation

The current official catalogue establishes four regular-production families: M100, M60 AquaLion, MP45 and M36.
Current product pages establish Swiss Sellita movement manufacture across the four mechanical families and detailed model-specific product specifications.
Current M100 and M36 product pages explicitly state manufacture by Vertex’s atelier in Switzerland.
Current first-party material also carries UK-workshop and M100 UK hand-assembly wording, so the completed-watch production route is recorded as conflicting rather than resolved by assumption.

International work

M100 and M36 current product pages state manufacture by Vertex’s atelier in Switzerland.
M100 and M36 use Swiss Sellita SW260-1 movements; M60 AquaLion uses the Swiss Sellita SW300-1; MP45 uses the Swiss Sellita SW510 MP route.
M60 movement testing described on the current product page occurs at the Swiss manufacturer before COSC certification and is not evidence of completed-watch British regulation.

Evidence gaps

Reconcile the current first-party conflict between broad UK-workshop / Hand Made in the UK wording, the Heritage page’s M100 hand-assembled-in-the-UK statement, and current M100/M36 Swiss-manufacture statements.
Identify the current final-assembly country and exact assembly stages for M100, M60 AquaLion, MP45 and M36 by model or production route.
Establish which current British-based person or team controls model-specific design and product development, including prototyping, technical revisions, supplier feedback, sample approval and final product sign-off, before Tier IV can be responsibly assigned.
If any current route is finally assembled within the qualifying territory, establish dial fitting, hand fitting, casing-up, post-casing timing, corrective regulation/rework or controlled rejection and recheck, functional testing and final release QC before Tier III can be considered.
For water-resistant current families, document completed-watch pressure-test scope, method, test pressure, location and traceability separately from movement-level or design-level certification.
