  • What cooperation models do you support? Are there any minimum order quantities (MOQ) requirements?
    We support two core models: ODM (Original Design Manufacturer) and OEM (Original Equipment Manufacturer). ODM provides a full-process service from requirement definition and solution design to mass production and delivery. OEM supports customization of appearance (watch strap/case), logo, boot screen, packaging, and instruction manual. Flexible minimum order quantities: basic logo engraving (watch buckle/case) starts at 100 units, boot screen customization at 5000 units, and packaging customization at 1000 units. Small-batch trial production can be negotiated to lower the entry barrier.
  • What is the product customization cycle? Can it meet the requirements for rapid time-to-market?
    Mature solutions can deliver samples in as little as 15 days. Customized solutions (including hardware function adjustments) have a sample cycle of 30-45 days, and mass production has a cycle of 45-60 days (including material preparation and quality control). We support a "solution reuse + partial customization" model to shorten the cycle, and also provide pre-certification services to help brands quickly seize the market window.
  • Can you provide global market compliance certification support? How is intellectual property protection handled?
    We can assist in obtaining mainstream global certifications such as CE, FCC, PSE, and BIS, ensuring that products meet the target market's access standards. Regarding intellectual property: the basic patents for customized solutions belong to us, while patents for exclusively developed functions/designs can be agreed upon to belong to the brand owner; both parties will sign a confidentiality agreement to strictly protect the client's brand information, design solutions, and other trade secrets.
  • Besides product manufacturing, what other supporting services do you provide?
    We provide full-chain support: ① Software: Custom APP development (iOS/Android), UI optimization, SDK/API integration; ② Localization services: Multilingual manuals, packaging design, regional compliance adjustments; ③ Supply chain services: Guaranteed inventory of core components, alternative supplier recommendations; ④ After-sales support: One-on-one technical customer service, bulk product repair guidance, and rapid replenishment response.
  • What are the support policies for order replenishment and product upgrades?
    Replenishment order production cycles are shortened to 30-45 days, and order quantities can be flexibly adjusted based on actual sales volume. Regarding product iteration, free software updates (including bug fixes and feature optimizations) are provided, and hardware upgrades (such as sensor replacement and battery life improvements) are available at cost price. Long-term partners enjoy priority production scheduling and reduced customized mold costs.
