CB01-GMT 90 Blue COSC Chronometer FULL STEEL

Essential in all its lines and finishes. It has been designed and produced to have the least impact on the environment. Only the functionally necessary has been produced. Nothing is superfluous, like it should be for a tool watch.

Orange GMT arrow-hands are iconic. On dashboard instruments, manometers and tools, the orange color is commonly used to identify a precise function thanks to its readability.

The 1990s evoke the last era of mechanical devices; the first website went online in 1991, then things started to change. Today, displays have become mainly digital.

When we first approached the project, we thought that we just had to use recycled materials to succeed. Soon we’ve realized that a true sustainable project is much more than that. It's about finding what is needed from an existing “circle”, transform it into a new “circle” and, finally, make it ready for its future “circle”. 

Producing in cycles.
 

This watch as an officially certified COSC (Contrôle Officiel Suisse des Chronomètres) chronometer. The movement is tested for 15 days at three different temperatures and in five different positions (3 o’clock, 6 o’clock, 9 o’clock, dial on top, dial on the bottom) with an average daily rate tolerance of −4/+6 seconds.

High precision.
