CB01-GMT 60 Green 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.

The 1960s were the original skin-diver case era. The lume of the skin-diver watches from this time has become light-brown.

The SLN « Old Radium » (which is clearly a faux-patina) allows the CB01-GMT to meet the watches coming from this decade. The white arrow contrasts harmoniously with the lume color and keeps the GMT function easily readable

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.
