Our industrial roots trace back to 1966, when our founding enterprise (PA Group) began machining high-precision mechanical watch components using Swiss-imported Petermann lathes. Through strategic Swiss technical collaborations, our manufacturing facility expanded from component micro-machining to producing complete mechanical movement calibers.
By the late 1980s, we successfully transitioned into high-yield quartz movement assembly, followed by our landmark launch in 1996 of the industry's first guaranteed waterproof watch series. Today, as a leading Chinese watch movement factory and global exporter, our vertically integrated facilities encompass raw alloy machining, wheel cutting, hairspring poising, clean-room caliber assembly, and multi-stage testing under one unified quality management standard.
Sub-micron tolerance micro-milling for mainplates, bridges, and pivot jewels.
Custom skeleton bridges, enlarged date rings, and bespoke rotor engravings.
Two-tier pressure verification: vacuum seating followed by immersion condensation audit.
Every mechanical movement undergoes 5-position rate calibration before packaging.
Technical performance metrics designed to assist B2B procurement managers, horological engineers, and microbrand founders in selecting optimal movement platforms.

Key technological shifts reshaping the wholesale watch movement manufacturing ecosystem across China and global horological markets.
Global microbrands are shifting rapidly from entry-level 21,600 VPH (3Hz) movements toward high-beat 28,800 VPH (4Hz) platforms. This transition delivers smoother second-hand sweep mechanics and superior kinetic resistance to wrist agitation.
Chronograph buyers increasingly demand mechanical tactile feel without mechanical maintenance costs. Meca-quartz calibers (like the VK series) utilize stepping motors for timing alongside heart-piece reset levers, dominating mid-tier sport chronograph manufacturing.
Wholesale watch buyers no longer settle for stock calibers. Market growth is heavily driven by factory-level modifications: customized skeleton bridges, black PVD/DLC mainplates, customized rotor shapes, and dual-language calendar discs built right on the assembly line.
Strategic insights for procurement directors navigating global supply chains, material costs, and lead-time optimization.
Chinese movement manufacturing is undergoing rapid automation. High-speed optical sensors automatically verify jewel seating depths and escapement alignment, reducing human handling errors and bringing batch variance below 0.02%.
With modern daily exposure to magnetic fields (smartphones, laptops, magnetic clasps), movement factories are replacing standard Nivarox balance springs with anti-magnetic silicon and specialized nickel-phosphorus alloys to eliminate magnetic rate deviation.
Traditional multi-tiered distribution channels are giving way to direct manufacturer-exporter partnerships. This model cuts procurement costs by 18-30% and allows brands to lock in stable component pricing despite fluctuations in raw brass and stainless steel markets.
Environmental compliance is now mandatory for European and American imports. Modern watch movement factories utilize cyanide-free electroplating and closed-loop water recovery systems, ensuring full compliance with EU REACH and RoHS environmental standards.
Essential guidance for international watch buyers, product designers, and supply chain specialists.
For standard off-the-shelf mechanical and quartz calibers (such as Seiko NH35A or Miyota 9015), our standard factory MOQ starts at 50 to 100 units in sealed factory trays. For customized calibers involving modified rotors, bespoke skeleton plating, or custom date discs, the MOQ is typically 300 to 500 units depending on tooling requirements.
Every caliber passes through a 3-stage quality check: First, automated optical testing checks train gear clearance and hairspring flat balance. Second, mechanical calibers are placed on Witschi Chronoscope timing machines to calibrate beat error (ms), amplitude (deg), and daily rate deviation across 5 positions. Third, cased units undergo our signature dry-then-wet pressure test (vacuum test followed by immersion condensation test) to guarantee 100% water resistance integrity.
Yes. We offer comprehensive rotor customization including laser etching, CNC hollow skeleton shaping, Geneva stripe (Côtes de Genève) engraving, and custom PVD plating (Gold, Rose Gold, Gunmetal Black, or Iridescent Blue). Samples can be produced within 10-15 working days following vector art approval.
Original Japanese calibers (such as Miyota 9015 or TMI NH35) are imported directly from authorized manufacturer channels in standard industrial packaging. Modified movements (like our Dandong 3235 or 3502 Skeleton series) build upon verified base architectures with custom aesthetic plates, extended power reserve barrels, or specialized calendar complications engineered in our precision workshops.
All movements are securely packed in anti-static, dust-free plastic trays (typically 100 units per tray block) with custom vacuum-formed shock-absorbing lids. Trays are desiccated, heat-sealed in moisture-barrier foil bags, and packed into reinforced double-wall corrugated export cartons to withstand international air and courier transport.
We provide a 12 to 24-month manufacturer guarantee against mechanical defect on all movement exports. In the rare event of a functional defect exceeding agreed batch tolerances (<0.5%), replacement movements or credit notes are provided immediately upon technical verification by our quality control engineering team.
