Ciso Tool
Explore our highly-acclaimed custom CNC machined components, watch straps, gaskets, and professional movement parts built to micron-level accuracy.
A statistical testament to our high-precision production ecosystem, advanced materials processing, and engineering rigor.
Dongguan Ciso Tool Co., Ltd. was founded in 2006 and is a professional manufacturer specializing in the research, development, and production of mid-to-high-end precision watch components 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.
Ciso focuses on the R&D and manufacturing of premium watch accessories, including watch dials, watch cases, watch straps, watch buckles, and precious metal components such as 18K gold watch parts and fine jewelry accessories. In addition, the company provides full ODM and OEM services, supporting complete watch customization from concept design and prototyping to mass production and assembly.
Analysis of critical technology shifts, changing supply chains, and engineering requirements shaping the horological market.
Modern luxury and industrial horology demand smaller profile architectures with tighter tolerances. Our advanced mechanical watch gear profiles are optimized to minimize friction coefficients down to microscopic levels, guaranteeing optimal kinetic transfer and extended power reserves in automatic and mechanical calibers.
The industry is transitioning from standard brass gears to high-durability composites. Manufacturers utilize grade 5 titanium, SUS316L stainless steel, and specialized copper alloys coated with advanced epilame or diamond-like carbon (DLC) layers. These materials ensure components withstand perpetual torque load without operational fatigue.
With smartwatches and hybrid movements gaining dominance, watch hardware components must offer physical resilience alongside structural integration. The demand for anti-magnetic spring bars, durable connector adapters, and custom aluminum protective cases is escalating exponentially to match hardware-level stress factors.
How we address the core operational friction points experienced by international watch brands, distributors, and engineers.
Guided by the principle of “Quality First, Integrity Supreme,” Ciso emphasizes excellence in every production process. The company implements rigorous quality assurance protocols, ensuring that each product meets international standards for durability, precision, and aesthetic refinement.
Through consistent quality and reliable service, Dongguan Ciso Tool Co., Ltd. has established long-term partnerships with well-known domestic brands and continues to expand its presence in global markets. The company is committed to honest cooperation, mutual growth, and long-term value creation with international watch brands, striving to elevate the artistry and innovation of modern watchmaking.
Global procurement teams prioritize vendors capable of maintaining dimensional deviations below 3 microns. Overcoming batch-to-batch variation in raw materials is paramount. Ciso implements real-time spectral analysis and coordinate measuring machines (CMM) to test raw stock prior to tooling, guaranteeing absolute physical stability.
Empowering global horological networks via advanced hardware tooling, specialized automation, and optimized production flow.
By leveraging industrial clustering in Guangdong's premier manufacturing zone, Dongguan Ciso Tool Co., Ltd. combines specialized raw materials sourcing with vertically integrated CNC machining, laser marking, metal finishing, and micro-assembly lines. This localized synergy decreases logistical lead times, increases response flexibility, and reduces processing costs relative to traditional Swiss facilities.
