Discover our flagship high-precision bezels featuring gold plating, sterling silver base materials, and handset VVS moissanite diamonds tailored for Sri Lanka's premium luxury watch modification hubs.
Sri Lanka, historically recognized as a central trade hub along the Indian Ocean maritime routes, has developed an increasingly sophisticated luxury retail and customization market. Key urban centers like Colombo, Kandy, and Galle are home to a growing demographic of watch collectors, luxury lifestyle enthusiasts, and independent horological workshops. With the rise of high-end commercial spaces and tourism-driven retail hubs, the demand for personalized, aftermarket watch modification parts—specifically custom bezels—has escalated significantly.
However, the local maritime environment of Sri Lanka imposes strict physical demands on watch components. The high humidity levels (regularly exceeding 80%) coupled with high atmospheric salt content along the coastal belts accelerate the corrosion and oxidation of sub-par metals. Ordinary gold-plated alloys and low-grade stainless steels quickly lose their luster, leading to micro-pitting and surface degradation.
To address this regional challenge, our factory exports advanced components using marine-grade 316L and 904L stainless steels, zirconia ceramic inserts, and thick, vacuum-sputtered PVD (Physical Vapor Deposition) coatings. Our 925 Sterling Silver range is coated with protective rhodium layers to ensure maximum resistance against salt spray and tropical wear, offering Sri Lankan customizers aesthetic excellence that endures the local climate.
How ceramic technology, custom metal gem-setting, and high-precision CNC manufacturing are defining the next decade of watch modification.
Modern bezels have shifted from soft anodized aluminum to high-hardness ceramic inserts. The raw material, zirconium dioxide (ZrO2) powder, is pressed under immense pressure and sintered at temperatures exceeding 1,400°C. This creates a surface virtually immune to scratches, remaining clean and pristine for generations.
The global trend of "Buss Down" or "Iced Out" watch modifications has skyrocketed. Standard cubic zirconia is no longer acceptable to discerning buyers. The industry standard has shifted to Lab-Grown Diamonds and VVS Moissanite, hand-set into precision-drilled recesses using CNC-controlled placement machines to ensure optical uniformity.
Wearable technology has merged with traditional luxury. Modern smartwatch consumers seek to upgrade their devices with high-grade steel and aluminum bezel protectors. This protection ring prevents structural impact damage while elevating the aesthetics of mass-market wearables to boutique watchmaking standards.
Founded in 2006, Dongguan Ciso Tool Co., Ltd. is a leading professional manufacturer specializing in the research, development, and production of mid-to-high-end precision watch components and complete horological solutions. Having evolved from an earlier specialized engineering framework, we have built a modern manufacturing enterprise with deeply integrated capabilities across conceptual design, structural engineering, and automated high-precision production.
Our independent industrial facility covers an expansive area of over 20,000 square meters and houses more than 500 skilled technicians. This workforce includes a dedicated, highly trained R&D team consisting of over 60 design and mechanical engineers. Leveraging state-of-the-art multi-station CNC centers, automatic lathes, precision wire cutters, and testing equipment, Ciso ensures unparalleled batch-to-batch consistency and accuracy for global watch brands, importers, and modding distributors.
We manage everything in-house: from initial prototype milling and advanced PVD color deposition to complex gemstone setting and final pressure testing. By maintaining absolute control over the production supply chain, we deliver OEM and ODM services that exceed international horological testing benchmarks.

Highly requested components for retrofitting classic divers and vintage sports cases, curated specifically for Colombo's boutique horologists.
Ciso's engineering development plans aim to integrate high-tech materials and micro-precision craftsmanship over the next five years.
We are consistently upgrading our vacuum sputtering facilities. By utilizing titanium carbonitride (TiCN) and chromium nitride (CrN) target materials, we achieve deeper blacks, richer gold tones, and vibrant dual-colors that are chemically bonded to the metal substrate. This guarantees that our custom bezels will not fade or peel, even in Sri Lanka's high-salinity coastal environments.
Achieving a sharp, bleed-free dividing line in dual-color ceramic bezels (such as our "Cola" style inserts) is a complex technical challenge. Ciso is implementing a new patented multi-shot ceramic co-injection process. This technique allows two distinct colored zirconia powders to be pressed and sintered together as a single block, creating a seamless line without physical weak points.
To meet the rising global demand for VVS moissanite and diamond bezels, we are developing automated robotic gemstone setting systems. CNC arms select and press each stone into place with calculated tension, followed by micro-claw crimping. This reduces production lead times by 40% while maintaining setting heights with a tolerance of 0.02mm, ensuring optimal light refraction and a brilliant shine.
Our quality assurance protocol is transitioning to a closed-loop system using automated optical metrology. Every single watch bezel is scanned in 3D using coordinate measuring machines (CMM) and compared against CAD models. Bezels with even minor concentricity deviations are automatically filtered out, ensuring 100% compatibility with OEM watch cases.
Whether you are an established jewelry store in Colombo or an independent online watch brand, we offer optimized logistics and customized production tiers.
We support Sri Lanka's growing watch modification community with low minimum order quantities (MOQs) for high-demand kits, including DW5600, DW6900, and GA2100 upgrades.
We offer custom packaging, custom engraving on inner bezel rings, and specialized toolkits so Sri Lankan retailers can sell our components under their own brand names.
Partnering with international air couriers (DHL, FedEx, UPS), we provide direct DDP (Delivered Duty Paid) shipping options to Sri Lanka, ensuring hassle-free customs clearance.
