Technical Scope

Finishing Textures & Treatments

From high-gloss luxury reflections to technical non-reflective matte surfaces for tactical instruments.

Distortion-Free Glare

Zaratsu-Inspired 8K Mirror Polishing

Flat lapidary disc polishing that produces razor-sharp reflections without the wavy distortion typical of standard soft buffing wheels.

  • Reflectance True black mirror reflection
  • Surface Roughness Ra < 0.015 µm
  • Bevel Preservation Zero edge rounding on chamfers
Directional Texture

Hairline Satin Brushing

Uniform, uninterrupted straight-line or circular graining applied along lugs, case flanks, and jewelry shanks for clean modern contrast.

  • Grit Options Fine 400 grit to bold 180 grit satin
  • Grain Alignment Strict linear parallel repeatability
  • Durability Resistant to light surface scratches
Technical Tactile Matte

Micro-Ceramic Bead Blasting

Automated pressure blasting with spherical zirconia beads producing smooth, non-reflective matte satin finishes ideal for field and dive watches.

  • Media Type Non-contaminating ceramic microspheres
  • Texture Feel Smooth velvet tactile touch
  • Reflectivity Zero specular glare
Engineering Precision

Surface Finishing Metrology Standards

Strict metrology criteria, equipment standards, and verification methodologies applied across every production batch.

Finish Designation Roughness Parameter (Ra) Visual Characteristic Primary Horological Application
8K Optical Mirror Ra 0.010 to 0.015 µm Distortion-free specular reflection Case chamfers, bezel tops, dress watches
Hairline Satin Brush Ra 0.15 to 0.25 µm Fine parallel directional linear grain Case sides, bracelet links, sports bezels
Ceramic Bead Blast Ra 0.35 to 0.60 µm Even diffuse matte non-directional texture Field cases, military timepieces, tool watches
Circular Geneva Wave Ra 0.08 to 0.15 µm Interlocking concentric ribbed arcs Oscillating rotor weights, movement bridges
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 physical reference parts to optimize toolpaths, clamping datums, and tolerance stack-ups. Comprehensive 2D manufacturing blueprints are delivered for review.

PHASE 02

Master Prototyping & CMM Audit

First-article pilot samples are machined on 5-axis equipment and routed directly to the metrology lab. Every critical datum, gasket seat, and thread pitch is measured using 3D CMM coordinate probes.

PHASE 03

Batch Machining & Artisanal Finishing

Batch manufacturing utilizes multi-axis Japanese CNC equipment, robotic surface buffing, 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.

Technical Guidance

Frequently Asked Questions

Common technical and commercial questions regarding our machinery capabilities, materials, and contract manufacturing standards.

How do you maintain sharp edges between polished and brushed surfaces?

We apply high-temperature protective masking tapes and precision CNC milled polyoxymethylene jigs to isolate individual facets, preventing edge rounding during buffing.

Can you polish Grade 5 titanium to a high mirror shine?

Yes. While titanium requires specialized diamond paste compounds and tailored wheel speeds, our master polishers achieve deep mirror reflections on Grade 5 titanium.

How do you clean polishing compounds from parts before plating?

All parts undergo a 5-stage automated ultrasonic cleaning line using heated alkaline baths and reverse-osmosis deionized water rinses to remove every trace of wax compound.

Will bead-blasted surfaces collect dirt or oil fingerprints?

Our use of spherical ceramic micro-beads peens the metal surface rather than tearing it, creating a closed microscopic texture that resists skin oils and dirt accumulation.
