Wrist watches dial

The foundation of a premium dial is usually Brass, though Stainless Steel or Carbon Fiber are used for specialized designs. Surface treatments are critical: Electroplating (such as PVD coating) ensures color longevity, while Sunray brushing, Enamel coating, or Guilloché patterns define the aesthetic value. For luxury segments, ensure the supplier uses genuine Mother of Pearl or applied indices (rather than printed) to enhance three-dimensional depth.

Compatibility is determined by the Dial Feet position, which must align perfectly with the specific movement model (e.g., Miyota, NH35, or ETA). You must verify the Center Hole diameter for hand fitment and the Total Thickness (usually 0.4mm to 0.8mm); a dial that is too thick may interfere with the clearance of the hands or the casing ring.

The most critical compliance factor is the Luminous Material. Ensure the supplier uses non-radioactive pigments like Super-LumiNova or Swiss C3/BGW9. For entry into the EU, the dial must be RoHS compliant, ensuring it is free from hazardous substances like lead or cadmium. If the dial features a brand logo, Trademark Authorization is mandatory to prevent customs seizure.

For Diver watches, high-contrast legibility and ISO 6425 standards for luminosity are essential. For Chronographs, the precision of the sub-dial alignment is paramount; even a 0.1mm deviation can lead to mechanical failure during assembly. Ensure the printing resolution is sharp enough to be legible under a 10x loupe.

Request a Pre-production Sample (PPS) before the full run. Watch dials are prone to micro-scratches and dust contamination; therefore, you should mandate that the supplier performs final inspection in a Class 1000 cleanroom and uses vacuum-sealed blister packaging for shipping to prevent oxidation and physical damage during transit.

Focus on the Mold Fee (Tooling Cost) and MOQ. Many suppliers on Made-in-China.com will waive mold fees for orders exceeding 500-1,000 pieces. Negotiate a Defect Rate Allowance (typically 1-2%) and agree on a Unit Price Tier that scales down as your volume increases. Always clarify if the price includes customized packaging.

Utilize the Secured Trading Services provided by Made-in-China.com to ensure funds are only released upon proof of shipment. For large orders, consider a 30/70 payment structure (30% deposit, 70% balance after passing a third-party pre-shipment inspection). This protects you against receiving sub-standard batches.

Since watch dials are small, lightweight, but high-value, Air Express (DHL, FedEx, or UPS) is the most efficient method, offering door-to-door tracking and faster customs clearance. Ensure the commercial invoice uses the correct HS Code (9114.30) to avoid tariff misclassification and ensure the goods are insured for their full replacement value.
