01 · MATERIALS

Natural Stone Dress Watch

Natural materials introduce variation into every stage of development. Stone thickness, reinforcement, marker fixing, hand clearance, and visual selection were engineered as one system rather than treated as a decorative dial change.

02 · PERFORMANCE

Compact 200M Diver

The challenge was not simply reaching 200 metres. Case thickness, crown sealing, bezel action, crystal geometry, lume, and bracelet fit were developed together to keep the watch compact without compromising functional targets.

03 · ARCHITECTURE

Integrated Sports Watch

Integrated-bracelet watches are developed as one metal architecture. Case geometry, first-link articulation, taper, tolerance, brushing direction and polished transitions were resolved together through multiple prototype iterations.

Mechanical Jump Hour

When the display changes, the entire watch architecture changes with it. Movement selection, module packaging, hand or disc clearance, dial structure, case height and serviceability were developed as one mechanical system.

PROCESS

A controlled path from design approval to production release

Design Review

Confirm design intent, target cost, movement, dimensions, materials, and production goals.

Engineering & DFM

Resolve manufacturability, interfaces, tolerances, materials, and critical component specifications.

Prototype Development

Build and review functional prototypes before production approval.

Revision Control

Record design changes, prototype issues, and approved specifications through each development round.

Golden Sample

Freeze the approved reference sample, BOM, drawings, finishes, and QC requirements.

Production Release

Move into production only after the approved sample, specifications, and inspection criteria are locked.

Manufacturing Network

Built around specialist manufacturing partners

HoroGrid is not tied to a single factory. We coordinate specialist partners across cases, dials, hands, bracelets, movements, assembly, and quality control based on each project's requirements.

ABOUT

Built around the product, not a single factory.

HoroGrid combines product development, engineering, and a specialist manufacturing network across Hong Kong and the Greater Bay Area to help independent watch brands move from concept to production.

Product-led development

Every project starts with the product — its design intent, engineering requirements, target cost, and production goals.

Specialist manufacturing network

Specialist manufacturing network

We are not tied to one factory. Each project is matched with manufacturing partners suited to its materials, construction, quality, and volume.

Prototypes, revisions, golden samples, production, and final inspection are managed through a structured development process.

Controlled through final release

Prototypes, revisions, golden samples, production, and final inspection are managed through a structured development process.

Bring the design. We’ll build the path to production.

Share your concept, rendering, CAD files, or existing prototype. HoroGrid will review the project and define the next steps toward engineering, prototyping, and production.
