Suspension System

Since the beginning of Formex in 1999, the patented Case Suspension System has been an integral part of every single Formex timepiece. Its two main functions are:

  • absorbs shocks to protect the mechanical movement from heavy impacts
  • adds to the comfort on the wrist by adapting to the wearer’s movements

Modeled with high-performance bikes and racing cars in mind, the Formex patented case suspension system works by integrating four springs between the upper and lower watch case. The result is the ultimate shock absorption system designed to protect the mechanical movement and deliver unparalleled comfort to the wearer.

This patented case suspension system brings form and function together for Formex Swiss watches. It’s functional, it’s state of the art engineering and it’s unquestionably unique – all in one watch.
