Production Protocol

Precision Manufacturing Workflow

From technical design audit and rapid pilot prototyping to full-scale batch fabrication and white-glove quality assurance.

PHASE 01

DFM Review & Tooling Setup

Our engineers inspect your 3D digital CAD files to optimize machining toolpaths, clamping datums, and tolerance stack-ups for cost-effective fabrication.

PHASE 02

Master Prototyping & Quality Audit

First-article pilot samples are machined on high-rigidity CNC equipment, measured on 3D CMM coordinate probes, and delivered for tactile and functional approval.

PHASE 03

Batch Manufacturing & Surface Lapping

Batch manufacturing utilizes multi-axis Japanese CNC equipment, robotic surface buffing, and master hand-applied satin graining under strict statistical controls.

PHASE 04

Cleanroom Assembly & Worldwide Logistics

All critical sub-assembly and casing occurs in ISO Class 10,000 cleanrooms to eliminate airborne contaminants, followed by global fulfillment drop-shipping.

Technical Guidance

Frequently Asked Questions

Common technical, operational, and commercial questions regarding contract manufacturing standards for this industry sector.

Can Fullion assist with 3D CAD modeling and engineering for new watch concepts?

Yes. Our horological engineers evaluate your 2D design renders, translating them into parametric 3D CAD models (STEP) with fully resolved crystal seats, gasket compression ratios, and crown stem heights.

What movements do you regularly integrate into custom watches?

We regularly integrate Japanese automatic and quartz movements (Miyota 9015, 9039, 8215; Seiko NH35, NH34 GMT, VK63 Meca-Quartz) and Swiss calibers (Sellita SW200-1, SW300, SW510 Chronograph; ETA 2824-2, 2892).

How do you ensure dust does not enter watch dials during assembly?

All dial mounting, hand setting, and caseback screw-down operations take place inside our ISO Class 10,000 cleanrooms with laminar flow benches and electrostatic ion blowers that neutralize airborne particles.

What is the typical production timeline for a custom watch collection?

Engineering review and prototype production takes 25 to 30 working days. Following prototype sign-off, full batch manufacturing and testing takes approximately 45 to 60 days.
