Stainless steel back watch

When sourcing these watches, distinguish between 'All Stainless Steel' and 'Stainless Steel Back.' The latter usually features an alloy or brass case with a steel case back. Ensure the back is made of 304 or 316L surgical-grade stainless steel to prevent skin irritation and corrosion. For the crystal, prioritize hardened mineral glass or sapphire coating to ensure scratch resistance in B2B retail environments.

For high-volume orders, Japanese Quartz movements (e.g., Miyota or Seiko/Epson) are the industry standard, offering high precision and low failure rates at a competitive price. If targeting the budget segment, Chinese Sunon or SL movements are economically feasible, but you must verify battery life (typically 12-24 months) to avoid after-sales complaints.

Standard fashion watches should meet at least 3ATM (30 meters) water resistance, which protects against splashes and rain. For sports or premium lines, aim for 5ATM or 10ATM. Ensure the supplier provides vacuum leak test reports for each batch and uses high-quality O-ring gaskets to maintain seal integrity over time.

To ensure legal entry and consumer safety, products must comply with RoHS (Restriction of Hazardous Substances) to ensure no lead or cadmium is present. For the EU, REACH compliance regarding nickel release is critical to prevent allergic reactions. US-bound goods must adhere to FTC labeling requirements, clearly stating the country of origin for the movement and assembly.

Always request a Pre-Shipment Inspection (PSI) by a third-party agency. Focus on the 'Drop Test' to ensure movement stability and the 'Cross-Cut Test' for PVD plating durability. Utilizing platforms like Made-in-China.com allows you to select Audited Suppliers, reducing the risk of receiving sub-standard components that differ from the initial sample.

Watch factories often have high MOQs (e.g., 300-500 pcs) due to component sourcing. To negotiate, offer a long-term forecast or suggest using existing mold cases to lower the entry barrier. For pricing, ask for a breakdown of costs (movement, case, strap, assembly) to identify where volume discounts can be applied, typically targeting a 10-15% reduction for orders exceeding 2,000 units.

Watches contain lithium or silver oxide batteries, classified as Section II Dangerous Goods (UN3091/UN3481). Ensure the supplier provides a valid MSDS (Material Safety Data Sheet) and UN38.3 Test Report. For air freight, use specialized couriers familiar with battery handling regulations to avoid customs seizures or shipping delays.

Avoid direct wire transfers to private accounts. Use Secured Trading Services provided by reputable B2B platforms like Made-in-China.com, which offer payment escrow and trade insurance. This ensures that funds are only released to the supplier once bill of lading (B/L) confirmation or inspection reports are uploaded and verified.
