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.

The Formex 4Speed TS 375 Automatic Chronograph is powered by an ETA caliber 7750 movement. The TS in the model number stands for Track Speed,  The Formex designation of a specialized driver watch.

The watch is looking pristine and there’s no indication that it was ever worn.

The watch is working and keeping a pretty precise time, but as for any other used or vintage watch, a basic revision is advisable.

Most of the watches that I am selling are liquidation or collector items, therefor I make no claims and give no warranty regarding continual accuracy of time keeping. Used, antique or vintage watches may need servicing, even if they are in good running condition. Unless otherwise stated they may need to be cleaned, oiled, adjusted and or timed. I cannot guarantee a used watch to be waterproof or water resistant.
