Explore our premium high-precision casebacks, engineered with military-grade tightness and optimized structural tolerances.
The Republic of Chile is establishing itself as a focal point for premium hardware and custom lifestyle micro-brands in South America. From boutique watch brands in Santiago seeking custom mechanical movements with exhibition casebacks, to heavy-duty mining, marine, and scientific telemetry devices operated in the extreme climates of the Atacama Desert and Patagonia, high-integrity hermetic sealing is critical.
Our company specializes in engineering high-performance watch casebacks that withstand extreme thermal fluctuations, high atmospheric pressure, and corrosive salty coastal environments typical of Valparaíso and San Antonio ports.
Developing premium casebacks requires a profound understanding of manufacturing metallurgy. As a trusted OEM/ODM partner, we provide Chilean watchmakers with access to structural options that ensure water-resistance ratings ranging from 5ATM to 100ATM.
By using CNC 5-axis milling machines, we produce complex geometries, such as deep-threaded casebacks, integrated sensor ports for wearables, and custom-engraved exhibition cases featuring synthetic sapphire display windows.

Doing business internationally requires smooth customs clearance. Thanks to the China-Chile Free Trade Agreement (TLC China-Chile), businesses importing watch components and customized steel casings can benefit from preferential tariff schemes, often resulting in 0% duty on high-precision mechanical parts.
We provide all necessary export documentation, including Form F Certificate of Origin, ensuring transparent tariff classifications (typically HS Code 9111.90 for watch parts). Additionally, our engineering practices meet rigorous European standards such as REACH and RoHS, ensuring that no lead or nickel contaminants are present in skin-contacting alloys.
HS Code Classification: 9111.90.00 (Parts of watch cases)
Free Trade Agreement (TLC): Form F submission unlocks preferential customs treatment.
Lead Time to Santiago: 5-7 days (Air Cargo via AMB Airport) / 30-35 days (Ocean Freight via Valparaíso Port).
