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.

Frequently Asked Questions

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

What is the difference between meca-quartz and traditional quartz chronographs?

Meca-quartz utilizes a physical mechanical gear train and heart-piece reset hammer driven by a quartz step motor, giving crisp pusher clicks and instant reset.

Can you ensure chronograph subdial hands reset precisely to zero?

Yes. Our cleanroom technicians calibrate hand staking under high-magnification microscopes to guarantee dead-center zero alignment.

What bezel scales can be manufactured on chronographs?

We manufacture tachymeter (speed/distance), telemeter (sound/distance), pulsometer (heart rate), and countdown bezel inserts.

Are chronograph pushers safe to operate underwater?

Standard pump pushers should not be pressed submerged. For dive chronographs, we engineer screw-down locking collars rated to 20 ATM.
