Ciso Tool
Discover our high-precision custom modules, calibration accessories, and advanced marking systems engineered to achieve micro-level tolerances and meet strict Swiss-grade parameters.
The contemporary watchmaking industry demands extreme precision. A microsecond variance in a mechanical movement can determine the positioning of a luxury brand in the global market. As a pioneering force, Dongguan Ciso Tool Co., Ltd. (founded in 2006) operates at the vital nexus of modern technology, micromechanical engineering, and premium watch component fabrication.
From complete horological diagnostic tools to custom-engineered steel, rubber, and precious metal components, our operation meets the rigorous technical standards defined by ISO certifications and Swiss-level test criteria. This white paper highlights how integration, high-tech manufacturing, and state-of-the-art diagnostic timing systems empower manufacturers and repair facilities around the world.
Dongguan Ciso Tool Co., Ltd. has evolved from an early precision engineering facility into a modern manufacturing enterprise with integrated capabilities. Operating an independent industrial complex in Dongguan, China, we specialize in the research, development, design, and high-volume production of mid-to-high-end watch components and complete horological calibration systems.
Our infrastructure contains advanced multi-axis CNC machines, computerized lathes, automatic spring-bar headers, and Swiss-grade optical testing laboratories. Our engineering team translates design blueprints into components with sub-micron accuracy. We focus on premium watch accessories—such as cases, custom dials, luminous hands, straps, buckles, and 18K gold/precious metal components—and supply high-speed laser marking systems and custom rubber/plastic gaskets for specialized industrial sealing applications.
Integrating acoustic sensor technology, micro-vibration analysis, and real-time processing to calibrate and verify luxury mechanical watch movements.
Captures the escapement wheel's ticks and tocks via high-sensitivity piezo-electric microphones. Translates raw vibration signals into clean waveform data to measure beat rate error and amplitude.
Supports rate testing across six standard positions (CH, CB, 9U, 6U, 3U, 12U) in line with COSC chronometer criteria. Identifies gravity-induced balance wheel imbalances.
Integrates with low-noise signal filtering circuits. Measures timing deviation down to ±0.1 seconds/day, providing watchmakers with immediate, actionable calibration data.
Each production step at Ciso—from raw material machining to final quality inspection—is documented, traceably measured, and continuously optimized.
Dongguan, located in China's Pearl River Delta, is a global hub for high-end micro-mechanics. The region's watch component manufacturing network offers distinct structural advantages for international brands:
Every step of the production process—from raw Swiss-grade steel and custom sapphire crystal growth to chemical gold-plating and high-accuracy surface treatment—is managed within a 50-kilometer radius. This close integration reduces transit times, minimizes logistics costs, and speeds up prototyping cycles compared to fragmented supply networks.
Our Dongguan facility combines skilled manual watchmaking assembly with modern robotic automation. Utilizing automated multi-station drilling, tapping, and wire-cutting machinery, we produce complex components with consistent structural integrity across high-volume production runs.
Ciso matches European and Japanese quality standards. We run incoming material spectroscopy, perform optical coordinate-measuring machine (CMM) testing, and run pressure chambers to verify water resistance up to 10ATM and higher. This robust process control ensures reliable long-term performance.
We provide full design-to-delivery production for global micro-brands and luxury watch houses. This includes custom 316L/titanium cases, unique chapter rings, and customized luminous hands with Swiss Super-LumiNova coatings.
We supply horological service centers, calibration laboratories, and watch repair chains with high-accuracy diagnostic tools, premium replacement parts, and high-performance marking lasers.
We manufacture precise custom gears, spring bars, crown stems, and micro-elastomer gaskets designed for high-stress industrial applications demanding long-term chemical resistance and durability.
We streamline international procurement with transparent operations, providing complete material certifications (RoHS, REACH), raw material spectroscopy reports, and insured air cargo delivery. Our dedicated international support team handles customs clearance documentation to ensure smooth delivery directly to your production facility or distribution centers.
