Ciso Tool
Initial engineered highlights targeting high-accuracy micro-precision systems and cross-industry smart wear integrations in the Ho Chi Minh City industrial sector.
Over the past decade, the manufacturing landscape in Ho Chi Minh City (HCMC), Vietnam, has evolved from a regional textile hub into a highly sophisticated center for high-tech micro-mechanics, precision engineering, and consumer hardware. As global brands diversify their watch supply chains across Southeast Asia, HCMC has emerged as a crucial node for assembling, finishing, and exporting high-tolerance horology accessories.
Leveraging direct logistics channels through Cat Lai Port and the proximity of industrial clusters in Binh Duong and Dong Nai, HCMC serves as an ideal base for watch dial development, structural components, and high-precision watch chapter rings (rehauts). Global brands seek high consistency, structural alignment, and strict environmental standards (RoHS/REACH compliant) to satisfy premium and luxury watch markets.
By integrating advanced CNC machining with expert manual polishing, local factories in HCMC can produce complex chapter rings with printed tachymeter, minute track alignments, or custom PVD coatings to support modern mechanical, quartz, and smartwatch lines.
Founded in 2006, Dongguan Ciso Tool Co., Ltd. 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.
By blending Dongguan's industry-leading production capabilities with regional distribution partners in Ho Chi Minh City, Ciso provides unparalleled delivery schedules, raw material sourcing, and localized technical services for watchmakers worldwide.
Our manufacturing facility features cutting-edge automated machining, drilling, and quality control systems designed to maintain strict tolerances down to the micron.
Often called the *rehaut*, the chapter ring acts as a structural and aesthetic bridge between the watch dial and the protective sapphire glass.
Ensuring that the indexes on the chapter ring line up perfectly with the dial markers. We achieve tolerances within ±0.02 degrees of alignment.
Sourcing premium 316L Stainless Steel, Aerospace Grade-5 Titanium, CNC Marine Brass, and lightweight Aluminum alloys to ensure extreme corrosion resistance.
Offering luxury finishing selections, including brushed satin, mirror-like polish, sandblasting, laser etching, and high-durability PVD color deposits.
Leveraging the robust industrial tooling of China alongside the dynamic assembly and regional trade perks of Ho Chi Minh City.

For modern watch brands, sourcing sub-components like the chapter ring or internal movement spacers requires a balance of quality control, cost efficiency, and supply chain transparency. A minor misalignment of 0.05 mm on a tachymeter bezel or chapter ring index can ruin the visual balance of a premium watch dial, resulting in rejected batches and damaged reputation. Working with a verified manufacturer like Dongguan Ciso Tool Co., Ltd. ensures precision at every level.
Our engineering team works closely with procurement managers to establish reliable quality control checkpoints:
