Ciso Tool
Explore our primary collection of high-specification watch movement parts, assemblies, and custom machining options engineered for reliability.
Founded in 2006, Dongguan Ciso Tool Co., Ltd. is a professional manufacturer specializing in the research, development, and production of mid-to-high-end precision watch components, timepieces assembly tools, 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.
Supporting complete custom watches from raw prototyping to final assembly.
CNC machining of titanium, carbon fiber, SUS304/316L, and precious metals.
Multi-station testing for dimensional accuracy, waterproofing, and chronographic deviation.
Inside Ciso's ISO-compliant production centers. Our heavy investment in multi-station tooling machinery ensures micron-level precision across all product runs.
As the mechanical watchmaking sector undergoes a revival in luxury tiers, the requirement for precision measurement and calibration has reached unprecedented levels. Watch calibration tools have transitioned from analog microphone-based timegraphers to highly integrated, multi-frequency optoelectronic and acoustic analysis systems. These systems evaluate not only rate stability (measured in seconds/day) but also mechanical health metrics like amplitude, beat error, and movement escapement efficiency.
Utilizing highly sensitive piezoelectric sensors that capture the escapement's ticking cycle (lift angle, lock, impulse, and drop) to diagnose minute friction variances within the gear train.
High-frequency photodiode arrays track the physical deflection of micro-components in quartz and hybrid smart wearable mechanisms, delivering calibration data down to the nanosecond.
Future-proof micro-stepper motors rotate movements automatically into 6 standard testing positions (CH, CB, 9U, 6U, 3U, 12U) to satisfy the ISO 3159 chronometer certification criteria.
Looking forward, Dongguan Ciso Tool Co., Ltd. is actively researching the integration of artificial intelligence (AI) with soundwave profile databases. By cross-referencing mechanical escapement noises against signature templates of popular calibers (such as Rolex 3135/4130, Miyota 9015, or Seiko NH35), our future systems will identify specific component defects—like a worn pallet jewel or unbalanced balance wheel—before disassembly is initiated.
Aligning high-precision tooling with international watch brands, large-scale distributors, and service centers.
Industrial-scale watch manufacturing and aftersales networks demand distinct, robust solutions. Small deviation rates can lead to warranty returns, brand erosion, and increased operational costs. Dongguan Ciso Tool Co., Ltd. resolves this vulnerability by supplying unified solutions that link component fabrication with calibration systems:
For luxury brands assembling mechanical watches, Ciso provides complete tooling setups. From high-tensile 65Mn spring steel movement parts to custom carbon fiber cases, all products are manufactured under tight tolerances. Implementing uniform tools reduces mechanical friction variances on assembly lines, stabilizing movement amplitudes.
Franchised service centers require reliable, repeatable test equipment. Our calibration devices deliver highly stable readings, preventing calibration errors. Technicians can measure rate deviations, amplitude levels, and beat errors with total confidence, regardless of local environment conditions.
"Manufacturing a quality watch requires more than fine components; it demands an ecosystem where the parts fit perfectly, and the calibration tools measure accurately. Vertical integration from raw materials to final calibration is our core methodology."
— Engineering Director, Dongguan Ciso Tool Co., Ltd.Operating from our 20,000 square meter facility in Dongguan, Ciso incorporates advanced CNC milling, drilling, tapping, and wire-cutting machinery. The integration of Factory 4.0 protocols guarantees that each run of precision components (e.g., custom adapters, spring bars, hands, or winding stems) maintains exact dimensional tolerance.
By retaining core processes—such as tooling design, CNC milling, precision stamping, sapphire crystal processing, and testing—in-house, we eliminate external supplier delays. Our automated CAM lathes and multi-station milling systems run on optimized schedules, helping to shield buyers from fluctuating raw material prices and logistics delays.
Navigating global trade compliance, safety guidelines, and environmental requirements.
Exporting technical equipment and high-end components to North America, Europe, and Asia-Pacific requires strict adherence to international regulatory systems. Ciso guarantees compliance through proactive validation and certified quality assurance steps:
Our watch components, including silicone O-rings, stainless steel spring bars, and copper watch hands, are fully certified lead-free and free of hazardous substances.
Our electronic calibration and laser engraving equipment meets CE electromagnetic safety and FCC standards, guaranteeing safe integration into Western workshop environments.
Ciso uses compliant export documentation, custom codes (HS Codes), and secure, moisture-controlled shipping materials to avoid transit delays.
