Ciso Tool
Explore our industrial-grade components, manufactured to rigorous engineering standards for high reliability and perfect performance
Established in 2006, Dongguan Ciso Tool Co., Ltd. is a premier manufacturing enterprise focused on the research, development, engineering, and precision production of mid-to-high-end watch components and complete horological micro-system designs. Guided by our foundational core philosophy, "Quality First, Integrity Supreme", we have transformed from a traditional component house into a vertically integrated, state-of-the-art facility serving global horological markets.
Operating an independent, specialized industrial plant spanning over 20,000 square meters in Dongguan, China, Ciso hosts over 500 skilled technicians. Our active R&D department features a specialized engineering cohort of over 60 senior engineers who continuously refine production workflows, material science applications, and structural optimizations for premium watch cases, custom dials, high-frequency oscillators, straps, and intricate micro-components.
We support global watch brands, industrial instrument manufacturers, and timekeeping suppliers through our full-suite OEM and ODM operations. Whether your business requires high-durability mechanical cases or custom structural movements, Ciso brings uncompromised mechanical integrity to every batch.
Technical insights into precision crystal oscillators, mechanical balance systems, and market evolution
As smartwatches, micro-electronics, and IoT terminals continue to shrink, there is a rising demand for ultra-compact crystal oscillators (such as the 1612 and 1210 packages). Our R&D team targets mechanical stability and structural optimization to withstand high-frequency vibrations while maintaining thermal equilibrium, preventing timekeeping drift across extreme temperatures.
The industry is transitioning toward Silicon MEMS (Micro-Electro-Mechanical Systems) technology due to its superior shock resistance and lower power consumption. As a forward-thinking supplier, we monitor material innovations to offer watch components and cases engineered to minimize electromagnetic interference, optimizing the performance of integrated silicon time-bases.
Global regulatory bodies like the EU demand strict compliance with RoHS, REACH, and CE certifications for all watch components. Our lead-free soldering, eco-friendly rubber gaskets, and low-emission metal treatments ensure that our entire catalog matches these international benchmarks, safeguarding your brand's regulatory compliance.
For global brands and industrial timing manufacturers, choosing a manufacturing partner requires balancing cost-efficiency with high consistency. A variation of even 1 micron in a watch winding stem or a bezel connector can cause assembly issues and compromise water protection.
Ciso addresses these demands with specialized manufacturing protocols:
By choosing Ciso, global procurement managers receive certified components, reliable shipping tracking, and comprehensive technical documentation for smooth international customs clearance.
Combining advanced automation, strict process controls, and specialized craftsmanship
Our facility features multi-station precision milling, drilling, and tapping setups. This allows us to complete complex machining steps in a single operation, reducing alignment errors and boosting production efficiency.
Our modern Swiss-type automatic lathes and CAM setups allow us to machine thin stems, custom crowns, and micro-pins down to tolerances of ±0.005mm, ensuring consistent quality for high-volume orders.
Located in Dongguan's manufacturing hub, we maintain direct partnerships with premium material suppliers for 904L/316L stainless steel, titanium alloys, ceramics, and specialty elastomers, protecting our production runs from material shortages.
Providing precision engineering across varied industries and environmental conditions
Our 10ATM and 20ATM turtle-style cases, complete with helium release valves and tight O-ring seals, prevent dust and moisture from reaching the movement during deep-sea dives.
Featuring custom 904L stainless steel links, VVS moissanite stone settings, and sapphire crystal backs, we supply high-end watchmakers with refined custom cases and bezels.
We manufacture lightweight, durable components like TPU bumpers, quick-release adapters, and protective frames for modern smartwatches, balancing impact protection with a slim profile.
Our custom mechanical components, winding stems, and micro-gears are widely used in specialized scientific meters and timing systems where mechanical reliability is key.
