Ciso Tool
Explore our flagship horological parts, custom dials, structural scale components, and manufacturing machinery.
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.
Our focus revolves around the engineering of micro-components where a single micron dictates the difference between flawless operation and mechanical failure. By combining cutting-edge CAD design paradigms with state-of-the-art multi-station CNC machinery, Ciso has positioned itself as a critical player in the global horological component supply chain.
Whether manufacturing highly calibrated watch scales, custom luminous ceramic bezels, or titanium winders, our processes adhere to rigid Swiss horological standards, establishing us as a top trusted supplier for luxury brands, modern micro-brands, and wearable-tech companies alike.
Our manufacturing hub integrates design, raw metal forging, CNC milling, laser-guided dial calibration, and dust-free assembly lines under one roof.
Providing enterprise-level OEM/ODM solutions to address the evolving structural demands of the modern timepiece industry.
Our watch dial scales use dynamic fiber laser marking systems capable of etching precise tachymeter, telemeter, and chronometer markers. This guarantees absolute compliance with micro-measurement tolerances down to ±0.002mm.
Utilizing high-grade TC4 titanium, 316L, and 904L stainless steel to forge robust outer hardware. Designed specifically for professional dive watches, aviation chronographs, and outdoor tactical smart wearables.
Bridging mechanical elegance and modern technology. Our production lines supply custom smart rings, antenna-retaining smartwatch bezels, and highly durable lug adaptors compatible with multiple operating systems.
The global luxury watch and smart wearable market demands unparalleled consistency. Fluctuations in raw material purity, thermal expansion in components, and incorrect scaling of dimensional parts can disrupt the balance wheel or winder systems of a mechanical caliber. As a global watch scale manufacturer and component supplier, Ciso maintains localized support nodes and high-volume output capacity to mitigate supply chain delays.
Our operations leverage advanced automated Swiss-style lathes, 5-axis CNC machining centers, and automated wire cutters to scale up manufacturing without sacrificing precision. We supply watch brands across Europe, North America, Japan, and Southeast Asia, adapting our logistics and customs procedures to guarantee streamlined delivery pipelines.
Each machine within our 20,000 square meter industrial facility is calibrated for extreme repeatability.
Strict quality assurance protocols deployed across specialized production divisions to guarantee high-consistency components.
Operating as a reliable partner in the horological space requires strict compliance with international manufacturing guidelines. Our manufacturing workflows are fully certified under ISO 9001:2015 quality systems, and our raw materials undergo periodic spectroscopy assays to guarantee chemical purity. Furthermore, all structural components meet EU REACH and RoHS environmental standards, ensuring complete safety for direct skin contact.
For our clients in Switzerland, Germany, and the United States, Ciso offers dedicated localized documentation support, including complete metallurgical certificates of conformity, material safety data sheets (MSDS), and strict mechanical tolerance data sheets. This level of transparency streamlines customs clearance and facilitates rapid integration of our components into assembly hubs in Europe and North America.
Our bespoke precision-engineered parts are highly adaptable across multiple industry applications:
How we are preparing to meet the micro-engineering and material demands of the next decade.
We are continuously upgrading our factory floors to feature sub-micron CNC centers with multi-axis robots. This automation minimizes dimensional variances between production runs. Concurrently, our newly integrated ultra-short pulse (femtosecond) laser marking machines allow for cold laser ablation, producing highly legible, razor-sharp watch dial scales and bezels without causing thermal distortion to the raw metal alloys.
Ciso is committed to integrating recycled titanium and bio-compatible alloys into our standard production portfolio. In addition, we are expanding our Physical Vapor Deposition (PVD) and Diamond-Like Carbon (DLC) coating processes. These innovations provide watch parts with superior scratch resistance, high aesthetic value, and enhanced resistance against corrosion from sweat and sea water.
Industry-standard technical insights concerning custom watch parts manufacturing and order processing.
Our advanced CNC and dynamic laser marking systems consistently achieve structural and dimensional tolerances within ±0.002mm. This level of precision is critical for the correct alignment of watch dials with the hands and the watch movement (such as NH35 or NH36 calibers) inside the watch case.
We specialize in manufacturing parts using premium materials, including TC4 Titanium (excellent strength-to-weight ratio and corrosion resistance), 316L and 904L Stainless Steel, Zirconia Ceramic (for scratch-proof luminous bezels), and premium cultured diamonds or Moissanite sets for custom iced-out designs.
Yes. We offer fully integrated ODM services where our 60+ engineering team develops concepts, creates CAD mockups, drafts production schematics, and designs molds. We also offer OEM services, manufacturing watch components strictly according to technical designs and blueprints provided by the client.
Each batch of watch crowns (such as screw-down options) and watch cases undergoes pressure testing inside specialized air and water chambers. We perform leak testing up to 10 ATM, 20 ATM, or higher depending on the specific requirements of our clients' dive watch or utility models.
Ensure superior performance and cosmetic appeal with our high-grade bands, connectors, spring bars, and custom modding parts.
