Direct access to our advanced custom watch modifications, components, and precision repair adapters engineered for high-durability applications.
An industry pioneer established in 2006, delivering comprehensive OEM/ODM watch manufacturing, structural component engineering, and complete micro-machining solutions globally.
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.
Understanding the structural shifts in procurement requirements across European, North American, and Asian horological hubs.
Global brands require materials like 316L and 904L stainless steel, aerospace-grade titanium, and high-purity carbon fiber. Ensuring biocompatibility, corrosion resistance, and RoHS/REACH compliance is no longer optional—it is a critical entry barrier for Western luxury markets.
High-end horology demands component dimensional variations within ±0.005mm. From spring bars to customized threaded watch crowns and mechanical case gaskets, micron-level consistency guarantees optimal performance and waterproof ratings up to 20ATM.
Procurement directors seek single-source manufacturers capable of managing the full production lifecycle. Integrating 3D structural CAD modeling, rapid alloy prototyping, CNC machining, automated PVD plating, final clean-room assembly, and waterproof testing mitigates production delay risks.
Equipped with state-of-the-art multi-station machinery to ensure precision across complex watch geometries and sub-millimeter component dimensions.
Aligning our manufacturing workflow with the highest industry metrics and global quality standards.
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.
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.
Our strict quality verification includes:
Every phase of our assembly and machining lifecycle is documented, offering complete transparency and batch traceability to meet audit requirements for international luxury groups.
We deploy closed-loop oil filtration systems in our multi-station CNC and wire-cutting lines to minimize environmental impact and maintain green-compliant production facilities.
Investing in emerging manufacturing technologies, automation, and composite materials to lead the next generation of horological development.
We are integrating fully automated robotic arms with our multi-station CNC and tapping systems to minimize manual handling of micro-screws, gaskets, and crown assemblies, ensuring zero-defect production.
Merging classic mechanical components with smart wearable technologies, such as advanced health sensors, Bluetooth antennas, and bio-compatible metal connectors for modern watch systems.
Adapting manufacturing practices to use 100% recycled metals and biodegradable rubber compounds, supporting brands that aim for carbon neutrality.
Addressing specific mechanical pain points and structural requirements across diverse high-performance sectors.
Developing effective seals requires highly precise machining. Our custom crowns combine 316L stainless steel cores with high-density EPDM/HNBR O-ring seals, preventing water ingress at extreme depths. We ensure thread pitches align precisely to prevent thread striping during assembly.
As wearable tech evolves, smart rings require hybrid engineering. We fabricate bio-compatible metal casings with built-in channels for flexible PCBs, matching micro-screws, and customized charging ports, allowing electronics to fit seamlessly into small profiles.
Our micro-machining capabilities extend to high-precision gaskets and washers for automotive applications, such as specialized Mercedes Benz sprinter head gaskets. This demonstrates our ability to work with tough sealing alloys and maintain exact dimensional accuracy.
