Ciso Tool
Explore our high-performance precision parts, customization structures, and industrial watchmaking tools engineered to meet extreme durability metrics.
Founded in 2006, Dongguan Ciso Tool Co., Ltd. is a prominent high-precision watch component manufacturer and developer of comprehensive production and diagnostic solutions. Over nearly two decades of engineering development, we have evolved from a specialized tooling facility into a state-of-the-art enterprise offering integrated services—from industrial prototype conceptualization to high-volume ODM/OEM production.
Operating a modernized manufacturing complex exceeding 20,000 square meters and staffed by 500+ professionals (including a dedicated R&D department of over 60 specialists), Ciso delivers components and precision testing setups for global watch manufacturers. Our core manufacturing expertise spans complex case fabrications, custom sapphire optics, high-durability gaskets, and components in premium alloys and 18K gold.
"Quality First, Integrity Supreme" underpins our commitment to Swiss-grade accuracy, high structural consistency, and reliable technical validation.
Undergoing rigorous testing is essential for horological products. Discover the standard configurations and precision tools that validate casing integrity, seal endurance, and chronometric accuracy.
High-performance diver watches and daily-wear sports casings must withstand structural pressure variables. Water testing equipment applies pneumatic differential testing to detect case deflection down to 0.1 microns, alongside high-pressure hydrostatic chambers capable of simulating depths up to 1,000 meters (100 Bar) in compliance with ISO 22810 and ISO 6425 standards.
Acoustic and optical timing systems measure movement behavior across multiple axis positions. By analyzing beat frequency vibration waveforms, the testing equipment calculates daily rate deviation (s/d), balance wheel amplitude, and escapement beat error (ms). Modern setups also incorporate magnetic field generation to test anti-magnetic threshold ratings.
Ensuring lifetime reliability requires cyclic stress testing of moving components. Automated mechanical arms perform winding crown torque testing, push-button click-cycling, bezel rotational wear profiling, and thermal shock chamber diagnostics (cycling from -10°C to +60°C) to prevent stress cracking or sealing ring degradation.
Ciso's 20,000+ sqm production facility houses precision tooling systems that achieve tolerances down to the micron level.
Why global brands look to South China—specifically the Dongguan-Shenzhen cluster—to optimize their testing instrumentation and precision engineering workflows.
The Dongguan industrial hub integrates raw material sourcing (such as medical-grade 316L/904L stainless steel, titanium alloys, and raw sapphire crystal boules), high-precision tooling design, specialized CNC milling, and surface treatment facilities within a 50-kilometer radius. This proximity shortens production cycles and accelerates engineering feedback loops compared to fragmented Western supply chains.
With a pool of over 60 mechanical design, electronic system, and metrology software engineers, Ciso translates custom OEM/ODM parameters into working prototypes. Our facility balances small-batch prototyping for independent watch brands with high-volume, automated production runs for mass-market enterprises.
Optimized production techniques, low-loss material nesting algorithms, and advanced multi-station machinery (such as our precision drilling, tapping, and wire-cutting units) enable competitive pricing. These savings allow brands to allocate more budget toward refining structural finishes and implementing multi-stage testing setups.
Navigating global import requirements and quality standards is critical for international watch brands, micro-brand developers, and laboratory managers. Ciso addresses these requirements through dedicated compliance protocols:
How quality control requirements shape the future of watch testing, from boutique micro-brands to high-volume assembly lines.
Smartwatches require testing setups that combine ingress protection testing (IP67/IP68) with optical-sensor clarity testing and high-frequency RF transmission checks. Ciso's testing equipment is designed to evaluate both mechanical seals and internal electronic performance without compromising diagnostic accuracy.
High-resolution camera arrays integrated with machine-learning algorithms are replacing manual loupe inspection. These systems automatically detect microscopic surface defects, dust particles under the crystal, dial print alignment errors, and bezel engraving deviations in seconds.
Global luxury brands are decentralizing their service centers. This shift drives the need for compact, multi-functional diagnostic units that combine timing, demagnetization, and waterproof verification into a single desktop footprint for retail boutiques and regional watch repair centers.
Technical answers to key questions about metrology, component integration, and manufacturing quality control.
Dry Testing: Uses air pressure and high-resolution displacement sensors. The watch is placed in a dry chamber where air pressure is increased. The sensor measures casing deformation down to fractions of a micron. If the casing expands and stays expanded, the watch is sealed. If it returns to its original size while under pressure, air has leaked inside. This method is non-destructive and safe for complete watches.
Wet Testing: The watch is placed in a chamber half-filled with water. The air above the water is pressurized, and the watch is then submerged. When the air pressure is slowly vented, bubbles will emerge from any leak points. This is useful for identifying the exact location of a seal failure but requires drying the watch afterward.
Engineered components built for durability, consistency, and compatibility with industry-standard movements.
