Ciso Tool
Engineered to exact tolerances and calibrated for Swiss & Japanese movement platforms utilized by Spanish ateliers and watch microbrands.
The Spanish watchmaking market is experiencing an extraordinary renaissance. Driven by a surge in independent boutique watch brands (microbrands) based in cities like Madrid, Barcelona, Valencia, and Zaragoza, as well as a highly specialized restoration ecosystem, the demand for precision-engineered watch parts has never been higher. Modern Spanish horological firms focus heavily on uniqueness, storytelling, and high durability to withstand the humid Mediterranean climates.
This climate factor makes anti-corrosion treatments, high-quality PVD coatings, and superior luminescent performance non-negotiable parameters for components. Microbrands like Tempore Lux, Unity, and Crepas have gained international acclaim by integrating premium components with unique designs. As Spanish brands scale, their purchasing requirements shift from off-the-shelf components to custom ODM/OEM watch hands with exact hand-setting clearance tolerances (micro-level accuracy).
Historically, Spanish watch repair houses and custom modding networks (*relojerías*) relied on fragmented domestic distributors. Today's global supply chain enables direct collaboration with advanced manufacturing hubs. By importing direct from ISO-certified Chinese facilities, Spanish entities secure access to Swiss-level tolerances without the prohibitive premium, establishing a significant competitive edge in both domestic and export markets.
1. Custom Lume Formulations: Brands require high-performance Swiss Super-LumiNova® (C3, BGW9, or custom tinting) or proprietary grade-A luminous pigments to offer superior visibility. Diver watches are particularly popular in the Spanish coastal regions.
2. Diversified Caliber Compatibility: The market relies heavily on robust movements. Watch hands must fit perfectly on Seiko NH series (NH34 GMT, NH35, NH36), Miyota (9015, 8215), Sellita SW200, and ETA 2824-2 platforms. The accuracy of the hand pipe dimensions is paramount to prevent hand slippage.
3. Materials and Finishes: Spanish consumers demand high-end aesthetics. Diamond-cut watch hands with polished facets, brushed surfaces, and sandblasted accents are standard requirements for premium collections. Materials such as brass, bronze, and stainless steel require precise electroplating (rose gold, yellow gold, gunmetal, rhodium) to prevent oxidation.
Founded in 2006, Dongguan Ciso Tool Co., Ltd. has established itself as an elite manufacturer specializing in the research, development, and production of mid-to-high-end precision watch components and complete horological solutions.

A booming sector in Spain where hobbyists and professional modders personalize Seiko movement watches (NH35, NH36, NH34 GMT). Our hands provide exact friction fits for hassle-free customization.
Maintain maximum compatibility across different movements with our quality-certified hands collection.
The production of watch hands is one of the most demanding sub-disciplines in micromechanics. While the dial serves as the canvas of a timepiece, the hands are the moving sculpture that marks the passage of time. For Spanish watch brands trying to establish a foothold in the competitive European market, the engineering quality of these small metal parts determines the brand's perceived value. A single microscopic imperfection on a watch hand, invisible to the naked eye but magnified under a sapphire crystal, can completely degrade a watch's prestige.
At Dongguan Ciso Tool Co., Ltd., we utilize advanced raw materials—including structural brass, H62/H65 copper alloys, premium-grade 316L stainless steel, and aerospace-grade aluminum. Our components undergo multi-phase surface treatments. High-precision chemical cleaning is performed to remove processing oils and micro-debris before the plating process. This step is critical for Spanish watch brands whose target consumers reside in coastal areas like Alicante, Malaga, and Mallorca, where high salt mist and humidity accelerate the corrosion of base metals.
Our manufacturing line integrates CAM Automatic Lathes and Medium Wire Precision Wire Cutting Machines to achieve exact tolerances for the mounting pipes (canon pinions). For instance, the hand hole diameters for the popular NH35 movement are exactly 1.50mm for the hour hand, 1.00mm for the minute hand, and 0.20mm for the second hand. Any deviation exceeding ±2 microns will lead to poor hand-fitting friction, causing the hands to slip or collide.
In modern tool watches and diver watches—which represent a huge portion of Spanish consumer sales—the application of luminescent material is a critical design feature. We deploy custom semi-automated luminous dispensing machinery to ensure uniform paint thickness across the hands. By managing viscosity and pigment concentration, we prevent common manufacturing issues such as luminous cracking, shrinkage, and uneven glow intensity.
Whether utilizing Swiss Super-LumiNova® (BGW9 with blue glow, C3 with green glow) or highly concentrated, cost-effective alternatives, our application thickness is monitored under computerized optical measuring systems. This ensures that the luminescence is not only bright but also lasts for hours, meeting ISO 3157 standards for timepieces.
We align our manufacturing quality control with international standards, ensuring compatibility with the repair and inspection frameworks of the Asociación Nacional de Profesionales Relojeros (ANPRE) in Spain. This collaborative standard-focused engineering reduces warranty claims for watch brands.
Every production run at Ciso undergoes rigorous testing, including temperature cycling, drop testing, salt spray anti-corrosion testing, and alignment inspections under 50x magnification. This commitment to precision minimizes the defect rate (AQL 0.4 or lower), ensuring that every watch hand set arriving at Spanish logistics hubs is ready for assembly.
