Case studies

Solutions built with our clients

Our case studies show how we support leading luxury and watchmaking brands in solving complex technical challenges. Each project demonstrates our ability to develop controlled, repeatable processes that meet exacting aesthetic and functional requirements.

  • When precision expertise moves across industries

    Building on decades of watchmaking expertise, CMSA applies extreme dimensional control to MedTech components. We manufacture very small parts with tolerances down to ±3 µm on selected diameters, supported by technicians who draw solutions from multiple industrial sectors. This cross-industry mindset enables robust answers to demanding MedTech requirements.

  • Selective plating for targeted performance

    Selective plating allows us to apply coatings only where needed, optimizing performance while reducing material usage. This capability supports complex parts requiring differentiated surface properties within a single component.

  • Platinum mass striking

    We master the striking of platinum masses for high-end watch components. The process combines force control, material expertise, and surface preservation to achieve precise geometry and flawless visual results with this demanding precious metal.

  • Real-time capability monitoring

    We implement real-time process capability tracking to ensure consistent compliance with tight tolerances. Continuous monitoring supports early detection of drift and strengthens process reliability throughout production runs.

  • Precision welding of titanium horns

    We developed a controlled titanium welding process that ensures repeatable geometry, clean aesthetics, and long-term structural integrity. This enables the welding of horns onto full-titanium watch cases while meeting the strict aesthetic and quality standards of Haute Horlogerie.

  • Mastering complexity in luxury components.
