Custom Watch Manufacturing Capability

In custom watch production, different case materials — stainless steel, ceramic, titanium, tungsten steel — require distinct machining strategies. Below is our standard production workflow, demonstrating our technical strength and structured manufacturing system.

1. Engineering & Design Confirmation

Every project begins with professional design documentation. Watch drawings are typically divided into:

  • Complete watch visual drafts (appearance drawings)
  • 2D technical drawings
  • 3D structural models
  • Assembly drawings
  • Detailed part data drawings

Designers create flat layouts, 3D models, and high-quality renderings to confirm aesthetic details. After approval, structural drawings are delivered to engineers for dimensional validation.

Before production starts, we confirm with clients:

  • 3D model files
  • Assembly drawings
  • Component data drawings

We normally produce a prototype sample first. Only after sample approval do we proceed with mass production.

2. Case Machining Process

Based on confirmed drawings, raw watch case blanks are produced from solid steel plates through high-pressure extrusion.

Step-by-step machining:

  • Rough Opening (Oil Machine): Removing excess material while leaving approximately 0.5mm margin.
  • CNC Precision Machining: Automatic lathes finalize dimensions according to technical drawings.
  • Internal Structure Finishing: Key dimensions completed within tolerance of 3–5c (1c = 0.01mm).
  • Drilling Operations: Crown tube holes and lug holes processed with precision drilling machines.
  • Secondary Surface Grinding: Upper and lower surfaces finished last to prevent external damage.

Different materials such as titanium, ceramic, or tungsten steel require adjusted cutting speed, tool selection, and cooling strategy. Certain designs require additional small-lathe or multi-axis CNC equipment.

3. Case Quality Inspection

After machining and polishing, each watch case is ultrasonically cleaned and transferred to the Quality Inspection Department.

  • Dimensional verification
  • Surface finish inspection
  • Thread accuracy testing
  • Structural tolerance confirmation

4. Component Quality Control

The Quality Department also verifies all external accessories supplied by partner factories.

  • Watch glass (sapphire / mineral)
  • Ceramic bezel ring
  • Waterproof gaskets (crystal & caseback O-rings)
  • Luminous filling & oil filling
  • Hardware components (springs, screws, fixing rings)
  • Crown tube & crown assembly
  • Caseback

Only accessories meeting technical standards are approved for assembly.

5. Inventory Management

All qualified components are registered separately in the warehouse system. After confirming that every required accessory has arrived, materials are transferred to the assembly department.

6. Final Assembly & Packaging

The packaging and assembly department integrates all components to complete the watch.

  • Movement installation
  • Dial and hand fitting
  • Case sealing
  • Water resistance testing
  • Final cosmetic inspection

Only after full inspection approval are watches prepared for shipment.
