Explore our advanced structural watch components, custom smart wear solutions, and micro-engineered replacement parts.
The global watch market is experiencing a profound convergence between classic mechanical design and micro-electronic intelligence. Global enterprise procurers, high-end brands, and distributors face increasing challenges in maintaining supply chain continuity, material consistency, and structural compliance. The requirement is no longer just for a components supplier, but for a vertically integrated engineering partner capable of bridging the gap between raw metallurgy and luxury finishing.
From custom 316L/304 stainless steel watch lugs to complex carbon-fiber casings and cutting-edge wearable health rings, the threshold of precision manufacturing has narrowed down to the micron level. A successful OEM/ODM framework must assure exact tolerances, reliable structural integrity, and clean aesthetic values that scale from prototype designs to bulk international shipments.
By leveraging advanced multi-station CNC milling and rigorous testing matrices, modern manufacturing facilities can eliminate the traditional latency period between CAD blueprint design and physical production, offering brands a distinct competitive advantage in time-to-market.
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.
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.
Our workshop integrates advanced multi-station high-speed milling, automatic lathe machinery, and precise testing tools.
Our production floor is designed around Lean manufacturing systems that optimize material flow and structural efficiency. Utilizing advanced Medium Wire Precision Wire Cutting Machines and CAM Automatic Lathes, we execute complex tooling pathways that traditional machinery cannot achieve. This enables us to maintain a constant output of high-tolerance watch components, replacement crowns for automatic movements (such as NH34, NH35, and ETA series), and high-rigidity structural pins.
Bridging the gap between classical micro-engineering and smart technology integrations.
Developing light-weight carbon fiber composite watch cases with a thickness of 16mm and diameter of 40mm, guaranteeing 10ATM water resistance.
Designing wearable health rings with biocompatible metals, integrated sleep metrics, and heart-rate sensors paired with ultra-compact circuit boards.
Implementing optical high-resolution camera sorting for watch springs, pins, and custom 1.5mm to 1.8mm stainless steel spring bars.
Transitioning watch components to recycled 316L and 904L steel alloys to meet global ESG standards and eco-certifications.
Multi-axis milling machines maintain 0.005mm accuracy on structural items like watch crowns, stems, and double open-head silicone strap switches.
Proprietary smelting setups for 18K solid gold components, rose gold vacuum plating, and specialized jewelry-grade structural pins.
Custom ODM solutions integrating medical-grade optical heart-rate trackers into traditional case-backs without altering watch aesthetics.
Operating a high-capacity watch component facility in Dongguan allows us to bridge manufacturing logistics with international standards. We supply brands in Switzerland, Germany, Japan, and the United States with compliant raw materials and fully serialized custom components.
All silicone straps, steel components, and gold alloys undergo strict toxicological testing.
Quality management systems implemented at every station from wire cutting to final testing.
Your unique dial and casing designs are fully protected under strict corporate security measures.
Redundant raw material storage to prevent delivery delays during global transport fluctuations.
Expert answers addressing the standard, material, and manufacturing questions of global watch developers.
We primarily utilize high-grade 316L and 304 stainless steel alloys for our structural watch lugs and quick-release spring bars. These materials provide outstanding corrosion resistance, high tensile strength, and excellent biocompatibility, ensuring no allergic reactions on wearer skin.
Yes. Our CNC milling lines are calibrated to manufacture watch accessories matching popular automatic movements, including Seiko NH34, NH35, NH36, NH38, NH39, NH70, and ETA mechanical variants. This includes custom crowns, stems, pointers, and case backs.
We provide full hardware-level ODM support for smart watches and smart health rings. This includes manufacturing titanium outer casings, incorporating heart rate sensors, wireless charging modules, and custom micro-electronics inside highly aesthetic form factors.
Our MOQ varies depending on the complexity of the part. For custom CNC machined brass rings and watch crowns, the standard MOQ is 1,000 units. For complete OEM watch projects (custom case, dial, and custom hands), our threshold starts at 500 units per style.
