Ciso Tool
High-precision replacement components, custom bezels, and durable movement parts engineered to original factory specifications.
How Dongguan Ciso Tool Co., Ltd. Bridges the Gap Between Heritage Craftsmanship and Modern Aerospace-Grade Precision Manufacturing.
In the global luxury watchmaking ecosystem, restoration and modifications require absolute precision, metallurgical authenticity, and micro-mechanical engineering excellence. Founded in 2006, Dongguan Ciso Tool Co., Ltd. has evolved from an early specialized tooling manufacturer into a global powerhouse in the research, development, and mass-fabrication of mid-to-high-end watch components. Today, we stand as a premier solution provider for global watch brands, restoration houses, and independent customizers demanding uncompromised component accuracy.
Operating an expansive, state-of-the-art manufacturing campus spanning over 20,000 square meters, Ciso employs a highly skilled workforce exceeding 500 professionals. At the core of our technical capabilities lies a specialized R&D department containing over 60 mechanical engineers and materials scientists. This extensive engineering infrastructure allows us to reverse-engineer vintage dimensions with micron-level tolerances, develop proprietary material blends (such as stable colored ceramics and structural titanium), and support the global watchmaking supply chain with complete OEM and ODM services.
Aligning B2B procurement pipelines with contemporary shifts in collector demand, sustainability, and material technologies.
Traditional aluminum watch inserts are yielding to engineering ceramics (Zirconium Dioxide) and ultra-hard Sapphire crystals. Modern restoration relies on manufacturing processes capable of sintering, diamond-machining, and anti-reflective sputtering to match modern luxury standards.
B2B watch companies require batch-to-batch consistency. Fluctuations in mechanical hardness or plating thickness can ruin assembly lines. Ciso implements rigorous metallurgical quality gates to guarantee identical material behavior in every batch of custom watch parts.
Today's restorers and brands demand single-source suppliers capable of managing 3D CAD modeling, multi-axis CNC milling, metal stamping, diamond polishing, and luminous filling (Super-LumiNova) under one roof, reducing lead times and supply chain overheads.
Witness our internal production workflow. We integrate top-tier equipment to achieve micro-machining and rigorous quality control.
Pioneering AI-integrated optical measurement and zero-tolerance materials science for the next generation of timepieces.
At Ciso, we approach watch restoration through the lens of continuous modernization. Our engineers are presently deploying a multi-phase technological roadmap designed to meet the rising complexities of both historical timepiece conservation and modern aftermarket customizations:
In vintage watch repair, recreating case components or lugs without altering the core alloy composition is critical. We are introducing sub-micron metal laser cladding systems. This allows our craftsmen to reconstruct microscopic, eroded sections of rare watch cases with matching 18K gold, 316L, or 904L structural alloys, preserving historical authenticity while re-establishing modern structural integrity.
Traditional ceramic bezels are limited in their spectrum due to pigments degrading under extreme sintering temperatures (above 1400°C). Our R&D team is developing low-temperature ceramic reaction-bonding techniques to create rich, durable colors (including deep emerald, midnight blue, and bicolor ceramics) that exhibit Vickers hardness levels exceeding 1500 Hv.
Integrating AI-assisted vision systems to check tolerances. Using coordinate measuring machine (CMM) systems integrated with artificial intelligence, we automatically identify structural variances in microscopic items—such as the teeth of winding stems or the hand clearance heights—down to +/- 2 micrometers.
Ensuring seamless international distribution through compliance, certificates, and secure supply chain protocols.
Procuring watch parts from overseas factories can present risks related to regulatory compliance, chemical safety, and intellectual property. Ciso mitigates these challenges through transparent, world-class operational standards:
