Ciso Tool
High-precision replacement components, advanced engineering materials, and premium watch case solutions engineered for strict global standards.
Established in 2006, Dongguan Ciso Tool Co., Ltd. has established itself as an industry-leading manufacturer specializing in the engineering, design, and large-scale manufacturing of high-end precision watch components and complete horological OEM/ODM solutions. Over the past two decades, Ciso has transitioned from a specialized component vendor into a vertically integrated global supplier powering mid-to-high-end watch brands across North America, Europe, and the Asia-Pacific region.
Operating out of a state-of-the-art 20,000 square meter industrial facility, Ciso employs a specialized taskforce of over 500 skilled professionals, backed by a dedicated R&D engineering division exceeding 60 specialists. Our facility utilizes dynamic manufacturing systems, integrating advanced computer-aided design (CAD), computer-aided manufacturing (CAM), and multi-axis CNC Swiss machining center technologies to ensure high dimensional accuracy across millions of units produced annually.
Decoding how enterprise buyers evaluate quality, risk, and manufacturing partners in China's horology export ecosystems.
Enterprise watch brands require watch components with micro-level tolerances. Precision parts like Swiss-caliber matching watch hands (such as NH35, NH36, or NH34 movements), sapphire crystals, and dimensional spring bars must measure precisely to ensure automated assembly lines function without component jamming. Ciso mitigates deviations by enforcing ISO 9001:2015 standards across all batches.
Global procurement teams are shifting away from standard metals toward advanced ceramics (Zirconium Dioxide bezel inserts), aerospace-grade carbon fiber watch cases, and S925 silver bezels set with VVS Moissanite. Sourcing professionals prioritize export suppliers who possess in-house materials sciences capabilities to manufacture scratch-proof, highly dense bezels and cases.
Managing multiple tier-2 and tier-3 component vendors introduces assembly misalignment risks. Ciso's consolidated B2B solutions cover everything from raw structural metal preparation (e.g., cold-drawn 65Mn spring steel, 304/316L stainless steel) to fully assembled wristwatches, simplifying importing logistics and lowering total cost of ownership (TCO).

Streamlining the path from raw billet processing to logistics clearance for global horological enterprises.
The durability of a watch movement relies on the tensile properties of its springs. We utilize premium, cold-drawn 65Mn spring steel for mechanical components, ensuring reliable tension recovery. For case and band components, we use 316L and 304 stainless steel alloys that are resistant to pitting corrosion, which is essential for marine-grade dive watches.
We process these materials using advanced wire cutting and Swiss-type auto-lathes, maintaining dimensional tolerances within ±0.005mm to prevent issues during final component assembly.
Ciso operates cleanrooms to prevent dust particles from entering case components during final assembly. Watch dial setting, hand installation, and case-back sealing are all performed under controlled environmental conditions.
Horology is evolving to bridge traditional craftsmanship with modern technology. Ciso's R&D division is focusing on three key technology areas:
First, we are engineering wearable tech integrations, such as our IP68 waterproof digital finger watches. This combines smart ring electronics with traditional quartz movements, utilizing micro-space packaging to protect components from moisture and dust.
Second, we are expanding our structural materials line with carbon fiber composites. These materials offer the light weight of polymer resins along with the high tensile strength of metal alloys, which is ideal for motorsport and outdoor sports-oriented watch lines.
Third, we are upgrading our dial engraving processes. By using high-speed 3D dynamic focusing Galvo laser marking systems, we can etch complex patterns onto hard ceramic, sapphire, and base-metal surfaces with high precision and speed.
Expanding CNC milling toolpaths for custom carbon composite watch cases and ceramic bezels.
Refining structural seals to improve IP68 ratings for smart rings and ultra-thin watch movements.
Deploying multi-station tapping and drilling equipment to scale up volume production while keeping labor overhead low.
Our quality-first philosophy is supported by documented testing processes and international regulatory compliance.
Every batch of 316L stainless steel, titanium, and 65Mn spring steel is chemically analyzed before processing. We provide raw material mill test certificates (MTC) to verify alloy composition and mechanical integrity.
Our components comply with EU REACH and RoHS environmental standards. For smart and electronic models, we maintain CE and FCC certifications to ensure smooth customs clearance worldwide.
All cases, back covers, and bezels undergo systematic inspections. This includes coordinates measuring machine (CMM) dimensional checks, salt spray corrosion testing, and water resistance verification.
