Ciso Tool
High-fidelity sealing solutions developed for watchmakers, service hubs, and advanced manufacturing operators across Singapore.
Analyzing current business demand and technical advancements in the Lion City.
Singapore is recognized globally as an advanced precision manufacturing, electronics assembly, and high-end luxury watch distribution and servicing capital. Located at the intersection of Asia-Pacific trade channels, the Singapore market demands extremely high-precision components that comply with stringent aerospace, watchmaking, and medical device sealing regulations.
With major luxury watch brands hosting regional repair academies and assembly lines here, the demand for precision O-Rings, back gaskets, and custom-formed elastomers has grown dramatically. Manufacturers must produce materials that withstand changes in temperature, humidity, chemical exposure, and mechanical stress without degrading. Ciso Tool answers this local demand by supplying custom-formulated sealing solutions that fulfill these exact operational parameters.
Innovating watch gaskets from basic rubber compound materials to advanced synthetic polymers.
FKM (Viton) and specialized Fluorosilicone are key for watches exposed to diving conditions and high chemical variance. They prevent moisture migration, resist degradation from body oils, and offer supreme flexibility at low temperatures.
Integrating the crystal or bezel directly with the gasket via overmolding techniques eliminates positional air gaps, improving dust exclusion and waterproof pressure ratings up to 30 ATM.
Precision watch assembly rooms demand dust-free environments. Advanced polymer gaskets are coated with electrostatic discharge (ESD) inhibitors, keeping tiny gears clear of static debris.
Professional manufacturer specializing in the research, development, and production of precision watch components.
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.

How our advanced manufacturing framework optimizes costs, lead times, and quality control.
Using top-tier CAM automatic lathes and multi-station precision milling systems, we design and build all gasket injection molds in-house. This capability allows us to achieve critical tolerances down to ±0.005mm. In-house mold fabrication reduces processing delays by up to 40% and ensures stable consistency during high-volume production runs.
Our production facility is strategically located in Dongguan, near major South China shipping networks (Shenzhen, Guangzhou, Hong Kong). Under the China-Singapore Free Trade Agreement (CSFTA), partners in Singapore enjoy reduced tariff rates and simplified customs clearance processes.
Engineered to perform in demanding test setups, robotic joints, and high-temperature environments.
Clear answers regarding watch gasket fabrication, materials, and ordering logistics for Singapore.
For high-grade luxury watches and precision tools, we maintain cross-sectional tolerances down to ±0.01mm. This tight window is necessary to achieve proper seating depth inside case back grooves, preventing gasket shear and ensuring reliable waterproof seals at depths up to 300 meters (30 ATM).
FKM (Viton) is dense and offers excellent resistance to synthetic watch lubricants, solvents, and perspiration. It is highly recommended for professional-grade dive watches. Standard silicone is more flexible and cost-effective, making it ideal for fashion watches. However, it displays higher gas permeability than FKM or NBR.
Yes. Dongguan Ciso Tool provides complete OEM and ODM services. We design and manufacture custom profiles based on customer engineering drawings, CAD files, or physical watch case samples, delivering ready-to-assemble solutions from initial prototypes to mass production.
For items in stock, shipping via air express typically takes 2 to 3 business days. For custom production runs (including new tooling development), the manufacturing phase is usually completed within 12 to 15 days, with transport to Singapore taking 3 to 7 days depending on whether air or sea freight is selected.
