Ciso Tool
Explore our elite engineering portfolio of custom OEM parts crafted for global luxury watch houses and enterprise brands.
Founded in 2006, Dongguan Ciso Tool Co., Ltd. has scaled from a dedicated precision tooling studio into an elite, internationally certified manufacturing enterprise. We specialize in the research, development, and high-precision production of mid-to-high-end watch components and complete horological OEM/ODM solutions.
From our headquarters in China's manufacturing heartland, we orchestrate an advanced supply chain network that integrates design, metallurgy, CNC micro-machining, precision surface decoration, and strict quality control. Our mission is to provide global enterprises and boutique brands with a resilient, vertically integrated manufacturing partner capable of converting raw industrial design into horological masterpieces.
Our capabilities encompass high-end case customization, sapphire crystal manipulation, ceramic dial and bezel insert synthesis, micro-spring bar manufacture, and specialized movement-compatible parts. Whether serving high-volume smart wearable developers or traditional mechanical brands, Ciso delivers uncompromised dimensional consistency and aesthetic perfection.
Step inside our highly digitalized manufacturing floor, engineered to maintain micron-level tolerances and scalable production.
Supporting high-volume, rapid-turnaround production lines with dedicated CAM precision lathe arrays for custom crowns, screws, and core watch pins.
The core of an exceptional watch lies in the science of its materials. At Ciso, we have established a dedicated metallurgy and surface treatment division to stay at the vanguard of watch engineering.
We work extensively with 316L Surgical-Grade Stainless Steel and 904L Corrosion-Resistant Steel, applying multi-axis CNC milling, diamond-paste polishing, and Physical Vapor Deposition (PVD) to obtain flawless surfaces. For premium lines, we process high-durability Zirconia Ceramic bezel inserts with customized diamond-cut indices and utilize high-purity single-crystal Sapphire lenses offering unparalleled scratch resistance.
Our technology roadmap actively integrates modern hybrid smart wearable structures—allowing traditional watch craftsmanship to blend with internal electronic sensors. We are also pioneering environment-compliant eco-alloys and low-nickel spring bars to fulfill global environmental requirements.
We streamline sourcing, compliance, and custom design for multinational brands requiring consistent, high-yield component output.
From CAD blueprint to custom watch cases, personalized dials, and hand-finished movement arrays, we support bespoke configurations matching specific market trends.
Dedicated account teams speak fluent English and technical design vernacular, ensuring smooth communication and reliable delivery timelines.
We implement rigorous testing protocols adhering to European RoHS and REACH standards. Each batch undergoes 100% cosmetic and functional inspection.
