Manufacturing Protocol

Precision Production Workflow

From technical CAD validation to cleanroom quality inspection, our engineering workflow ensures strict repeatability.

PHASE 01

Engineering DFM & Blueprints

Our engineers inspect your 3D CAD files or reference samples to optimize wall thicknesses, gasket compression tolerances, and tooling paths. Comprehensive manufacturing blueprints are delivered for review.

PHASE 02

Master Prototyping & Testing

First-article prototypes are machined via 5-axis CNC and assembled in our cleanroom. Each prototype undergoes dimensional verification, dry vacuum and hydrostatic water testing, and hand fitment audits.

PHASE 03

Precision CNC Machining & Finishing

Batch manufacturing utilizes multi-axis Japanese CNC equipment, robotic surface polishing, and master hand-applied satin graining. Components undergo strict optical inspection before movement casing.

PHASE 04

Class 10,000 Cleanroom Assembly & QC

All watch casing and critical sub-assembly takes place in ISO 14644 Class 10,000 cleanrooms to eliminate airborne dust. Every completed piece passes 48-hour mechanical timing and dual pressure tests.

Procurement Guidance

Frequently Asked Questions

Common technical and commercial questions regarding custom horology manufacturing and private label supply.

How do screw-down crowns achieve water resistance?

When screwed in, internal gaskets are compressed against the crown tube and case wall, creating a hermetic seal that prevents water ingress under pressure.

Can you emboss our custom brand logo on the crown face?

Yes. We offer deep relief CNC micro-milling, fiber laser engraving, and color enamel infill to showcase your brand emblem.

Are replacement crown tubes included with crowns?

Yes. We supply matching precision-threaded crown tubes designed for press-fit or threaded assembly into your watch case.

What prevents threads from stripping on screw-down crowns?

We engineer specialized thread pitch geometry and utilize work-hardened 316L stainless steel to prevent cross-threading and thread fatigue.
