Ciso Tool
Explore our state-of-the-art instruments, calibration systems, and replacement mechanisms engineered to satisfy rigorous horological standards.
Dongguan Ciso Tool Co., Ltd. was founded in 2006 and is a professional manufacturer specializing in the research, development, and production of mid-to-high-end precision watch components and complete watch solutions. Formerly operating under an earlier corporate structure, the company has grown into a modern manufacturing enterprise with strong integrated capabilities across design, engineering, and precision production.
The company operates an independent industrial facility covering over 20,000 square meters and employs more than 500 skilled staff members, including a dedicated R&D team of over 60 professionals. With advanced production equipment, strict quality control systems, and experienced technical personnel, Ciso is committed to delivering high-precision, high-consistency products for global watch brands.
Ciso focuses on the R&D and manufacturing of premium watch accessories, including watch dials, watch cases, watch straps, watch buckles, and precious metal components such as 18K gold watch parts and fine jewelry accessories. In addition, the company provides full ODM and OEM services, supporting complete watch customization from concept design and prototyping to mass production and assembly.
A comprehensive analysis of manufacturing parameters, micromechanical calibration, and OEM/ODM engineering in contemporary horology.
The global horology market demands sub-micron tolerances, requiring specialized tools that prevent scratching, alignment deviation, and mechanical failure. Contemporary watch movement assembly, particularly for calibers like the NH35, ETA 2824, or custom luxury movements, depends heavily on the ergonomic, structural, and mechanical characteristics of the toolset utilized during assembly, servicing, and adjustment.
Historically, watch toolsets were generalized hand-tools. Modern manufacturing, dominated by automated CNC systems, laser etching, and ultra-precise mechanical linkages, has forced a shift. Tooling must now prevent torque overload on tiny screws, provide uniform tension on cases and crowns, and ensure that micro-machined components like dial indicators, hands, and stems are set without damaging surface platings, coatings, or delicate luminescent paint.
As a premier OEM watch tool set supplier, Dongguan Ciso Tool Co., Ltd. implements advanced metallurgy to balance hardness and ductility. Standard tooling often degrades under repetitive pressure, leaving metallic flakes in movement gear trains. Ciso addresses this by selecting and heat-treating materials for specific applications:
Our engineering team transforms concepts into production-ready watch components and assemblies through a rigorous multi-stage workflow:
Step inside Dongguan Ciso's industrial complex, featuring precision milling, wire cutting, and multi-station calibration machines.
Ensuring metallurgical integrity and dimensional consistency across international watchmaking hubs.
Guided by the principle of "Quality First, Integrity Supreme," Ciso emphasizes excellence in every production process. The company implements rigorous quality assurance protocols, ensuring that each product meets international standards for durability, precision, and aesthetic refinement.
Our manufacturing and processing techniques comply with REACH, RoHS, and CE guidelines. This ensures that accessories, including our premium rubber gaskets and nickel-free steel watch crowns, are safe for direct skin contact and long-term daily wear.
Operating a global supply chain, we offer specialized door-to-door air freight and customs clearance support to major watchmaking centers in Switzerland (Geneva, La Chaux-de-Fonds), Japan (Tokyo, Nagano), and the United States.
Through consistent quality and reliable service, Dongguan Ciso Tool Co., Ltd. has established long-term partnerships with well-known domestic brands and continues to expand its presence in global markets. The company is committed to honest cooperation, mutual growth, and long-term value creation with international watch brands, striving to elevate the artistry and innovation of modern watchmaking.
Over the next decade, the watchmaking industry will experience deeper integration with digital and micro-electronic systems. In response, Ciso's technical roadmap includes developing toolsets specifically calibrated for smart wearable assembly (such as OEM Smart Rings) and automated optical checking lines that test gasket seal integrity under high pressure. By combining heavy machinery, like CNC mills, with cleanroom manual assembly benches, we bridge the gap between traditional craftsmanship and modern technology.
Technical and logistics answers for watch brands, independent horologists, and tool distributors.
We utilize surgical-grade 316L and 304 stainless steel for mechanical strength and corrosion resistance. For movement-facing tools, we use non-magnetic beryllium copper, brass, and carbon fiber to prevent structural wear, scratching, or magnetic transfer to hairsprings.
Yes. We specialize in custom toolset organization, custom laser engraving on tools (utilizing our advanced fiber laser marking machines), and specialized kit designs for repair chains, distributors, and brand service centers.
Ciso uses automated multi-station precision drilling, milling, and wire-cutting machinery. Our quality inspection facility employs coordinate measuring machines (CMM) and optical comparators to verify dimensions to within ±0.002mm tolerances.
Standard prototype verification takes 7 to 14 days. Upon design approval, mass production cycles generally run 30 to 45 days, depending on geometry complexity, surface finishings, and batch quantity.
All seals, gaskets, stainless steel parts, and plating formulations strictly follow international RoHS, REACH, and California Proposition 65 mandates, ensuring safety for global export and distribution.
Refined case accessories, high-grade watch hands, smart wearables, and movement winding components for industrial production.
