Watchmaking: precision heat treatment for high-end Swiss watch components

Watchmaking 3

The heat treatment of watch components is rooted in traditional techniques and expertise passed down through generations.

Historically, the quality of results depended heavily on the experience of the hardener and the gradual evolution of methods and equipment.

Modern watch manufacturers now rely on high-performance furnaces to ensure flawless metallurgy, repeatability, and compliance with strict safety and quality standards. Codere offers both standard solutions tailored to watchmaking and fully customized systems based on specific technical requirements.

Watchmaking Industry Challenges

Manufacturers face several important constraints:

  • Extremely high precision in thermal cycles
  • Repeatable results for steels, precious metals, and alloys
  • Clean, oxidation-free atmospheres
  • Traceability of all treatments
  • Compatibility with watchmaking dimensional tolerances and micro-components

Codere systems are designed to support these exacting requirements.
