Discover engineered solutions designed for mechanical movements, luxury modifications, and industrial precision testing.
Founded in 2006, Dongguan Ciso Tool Co., Ltd. has established itself as an industry-leading manufacturer specializing in the research, development, and production of mid-to-high-end precision watch components and complete horological solutions. Formerly operating under an earlier corporate structure, our organization has evolved into a modern, integrated manufacturing powerhouse with unified capabilities across aesthetic design, precision engineering, and specialized production.
Operating from an independent, state-of-the-art industrial facility in Dongguan, China—the epicenter of global micro-machining—Ciso coordinates over 500 professionals and a highly specialized R&D core. Guided by the core principle of "Quality First, Integrity Supreme," we implement rigorous quality assurance protocols to guarantee that every component aligns with international quality benchmarks.
Ciso focuses on the manufacturing of premium watch accessories, including high-accuracy dials, premium-grade cases, straps, clasps, and precious metal components such as 18K gold elements and fine jewelry accents. Furthermore, our comprehensive ODM and OEM setups facilitate complete horological customization—taking watch projects smoothly from conceptual visualization and CAD modeling to prototyping, structural testing, and scale assembly.
The international watchmaking landscape is undergoing a significant transformation. Traditional mechanical watches and advanced smartwatches now share critical dependencies on high-precision micro-components. Sourcing from a premier Chinese manufacturing facility is no longer just about optimizing costs; it has become a strategic step to access advanced manufacturing tech, agile R&D pipelines, and high-performance materials.
The term "Watch Manual" refers to both manual winding movement components (stems, winding assemblies, and mechanical adjustments) and watchmaker manual tools (connection shafts, spring needles, and lug tools). These products demand extreme tolerances, often within ±0.002mm. Precision watchmaking factories in China have invested heavily in high-performance CNC centers, automatic Swiss-type lathes, and optical testing machines to supply movements and cases that match Swiss and Japanese standards.
Modern watch manufacturers must satisfy diverse international standards. Consumers demand robust wear-resistance, hypoallergenic materials (such as SUS316L stainless steel or Grade 5 Titanium), and luxury aesthetics like hot-blued steel hands or iced moissanite bezels. Our engineering workflows adapt to these dynamic market trends by combining traditional metalcraft techniques with computer-controlled machining platforms.
To maintain strict quality consistency across millions of units, Dongguan Ciso Tool Co., Ltd. operates a highly optimized machine park. Here is an inside look at our manufacturing processes and in-house machining equipment:
Our factory features high-stability multi-station milling, drilling, and tapping machines that run on advanced CNC pathways. This setup enables high-throughput production of critical watch structures without sacrificing detail. Additionally, CAM automatic lathes and medium-wire precision cutting units handle the production of complex mechanical items like movement stems (NH35/NH36 compatible), spring bars, and case backs.
Shipping high-precision micro-hardware globally requires absolute alignment with complex customs rules and material regulations. As a reliable manufacturing partner, Ciso ensures all exported products meet standard global environmental requirements.
Every batch of 316L Stainless Steel, Titanium, and epoxy resin used in our production undergoes extensive composition verification. Our alloys comply with the European REACH Regulation and RoHS Directives, preventing heavy-metal contamination and ensuring all metal surfaces are hypoallergenic for long-term wear.
To support overseas brands, we customize our packaging solutions using shockproof, anti-static EVA foam inserts and moisture-sealed outers. These measures ensure delicate watch parts, decorated hands, and replacement bezels arrive in perfect condition. Our customs department handles export documentation, providing Harmonized System (HS) codes to ensure hassle-free clearance through international ports.
Our precision watch accessories support diverse business models across the global horological sector. We adjust our production setups to match these specific commercial contexts:
Providing high-tensile NH35/36 winding stems, ETA-compatible hands, and replacement crowns. Ideal for professional watchmakers, repair centers, and custom-mod brands.
Manufacturing premium bezels set with moissanite or amethyst. This gives watch brands access to high-end customization options without requiring in-house gemstone setting.
Producing high-durability epoxy resin gaskets and CNC insulation parts. These meet the demands of precision industrial equipment and watch testing machines.
Ciso is actively expanding its manufacturing capabilities to stay at the forefront of the industry. We are currently implementing three core technological updates:
Integrating automated camera inspections onto assembly lines to screen for micro-scratches and dimensional deviations below 1 micron.
Using high-precision fiber laser markers to create clean logos, serialized tracking codes, and detailed dial designs.
Adopting circular lubrication cooling systems and using recycled metal alloys to support green manufacturing practices.
