Liuzhou Yingyang Trading Co., Ltd

Manufacturing Scale and Annual Output
Operating from a 5,000sqm vertically integrated production facility in Liuzhou, China, we leverage 12 semi-automatic assembly lines to achieve an annual output of 80,000 timepieces. Our factory features dedicated zones for precision injection molding (for cases and straps), movement calibration, and quality control, enabling flexible large-batch and small-custom orders. Advanced CNC machining centers ensure micron-level tolerances for components like bezels and dials.

Expert Team and Craftsmanship Innovation
With over 100 skilled technicians, including over 20 horology specialists formerly employed by Swiss-certified factories, we combine traditional craftsmanship with modern technology. Our R&D team holds 15 patents in movement stabilization and decorative techniques (e.g., diamond-cut indices, anti-tarnish plating). All production supervisors are certified by ISO 9001:2025 and Horotec Precision Assembly, ensuring expertise in handling Miyota/Seagull movements and custom modifications.

Stringent Quality Control Protocol
Every timepiece undergoes a 72-hour, 7-stage validation cycle:

1. Material Screening: XRF testing for hypoallergenic alloys (316L steel/IP rose gold plating)
2. Movement Accuracy: COSC-style chronometry checks (5 sec/day tolerance)
3. Environmental Stress: 3ATM water resistance, 15 deg C/0 deg C thermal cycling
4. Aesthetic Durability: 500-cycle scratch/UV fade resistance verification. Rejection rates are maintained below 0.8% through AI-powered optical inspection systems.

Agile Customization and Market Responsiveness
We support end-to-end OEM/ODM solutions with 15-day rapid prototyping (3D modeling functional sample). Current market-driven offerings include:

• Luxury-Inspired Designs: Skeletonized dials with turbine motifs, ceramic bezel inserts
• Material Innovations: Bio-based silicone straps, recycled tungsten cases
• Smart Integration: Hybrid quartz movements with Bluetooth 5.3 fitness tracking

Design teams analyze global trend data weekly to refresh our catalog quarterly.

Global Compliance and Ethical Operations
Certified by SGS for RoHS/REACH materials compliance, we strictly avoid counterfeit branding. All products are shipped with generic packaging and unbranded dials, aligning with international IP regulations. Our transparent supply chain traces conflict-free minerals and audited labor practices.
