Ciso Tool
Dongguan Ciso Tool Co., Ltd., founded in 2006, is a titan in the research, development, and production of mid-to-high-end precision watch components. Our transformation from a specialized workshop to a 20,000-square-meter modern industrial facility represents our unwavering commitment to the horological industry.
With a workforce of over 500 skilled professionals and an internal R&D team exceeding 60 engineers, we integrate design, precision engineering, and mass production to serve global brands with uncompromising quality.
Our expertise spans the entire spectrum of watch accessories: Watch Dials, Cases, Straps, and notably, Precision Watch Clasps. We specialize in working with 316L Stainless Steel, Titanium, and 18K Gold to create functional art pieces for your wrist.
Guided by "Quality First, Integrity Supreme," Ciso implements rigorous ISO-aligned protocols. Every watch clasp undergoes tens of thousands of cycle tests to ensure the locking mechanism remains crisp and secure for the lifetime of the timepiece.
The global watch market demands extreme resilience. Dongguan, China, serves as the heart of this supply chain. Our facility at Ciso Tool Co., Ltd. leverages this ecosystem to provide lead times that are 30% faster than European counterparts without sacrificing the micron-level precision required for luxury clasps.
By controlling everything from raw material sourcing (316L/904L steel) to final PVD coating and assembly, we eliminate the risks of multi-tier vendor delays. This vertical integration is the cornerstone of our "Information Gain" for clients—providing them with data-backed transparency at every step.
We do not compete on "cheapness." We compete on "Value Density." By utilizing multi-station precision milling and automated CAM lathes, we achieve consistency that reduces the "Total Cost of Quality" for international watch brands.
Integrating NFC and biosensors into the watch clasp for contactless payments and health tracking, maintaining the aesthetic of a classic mechanical watch.
Our roadmap includes the transition to 100% recycled stainless steel and eco-friendly PVD processes to meet the EU's strict environmental mandates.
Advanced ratchet-style extension systems for localized professional diving applications, allowing tool-less adjustment over wetsuits.
Refining our proprietary micro-adjust mechanisms that allow 0.5mm increments, catering to the varying wrist sizes of the global population.
Our 20,000m² facility is equipped with state-of-the-art machinery to ensure every clasp and component meets Swiss-equivalent standards.

All materials used in Ciso clasps are REACH and RoHS compliant. We provide complete material certification (MTR) for every batch, ensuring your brand meets international regulatory standards in the EU and North America.
We offer DDP (Delivered Duty Paid) shipping options to Europe and the US, handling all customs clearance and localized taxes to simplify your procurement process.
As an OEM/ODM leader, we implement strict Non-Disclosure Agreements (NDAs) to protect your unique clasp designs and engineering innovations.
We primarily use 316L and 904L stainless steel due to their superior corrosion resistance and polishability. For luxury tiers, we provide 18K solid gold, Grade 5 Titanium, and Carbon Fiber components.
Yes. Our R&D team of 60+ professionals specializes in ODM/OEM services. We can handle everything from 3D CAD modeling and rapid prototyping to final mass production with custom logos engraved via laser or CNC.
Each clasp design undergoes a "Fatigue Test" involving 50,000 open/close cycles. We also perform salt spray testing for 96+ hours to ensure water resistance and finish durability.
Standard components usually ship within 15-20 days. Fully custom OEM clasp projects typically require 45-60 days, including the tooling and sampling phase.
