CB01 GMT 90
100% Circularly produced
100% Recycled Stainless Steel – PuReSteel™
Repurposed Soprod C125 automatic GMT movement
Handmade sustainable leather strap
Our factory direct promise
The CB01 GMT NK90 is a raw and "naked" watch by design an technical conception. 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.
87.59% Sustainability score
The CB01 GMT's construction, production process and local supply chain give it an 87.59% sustainability score. This makes it 2.09 times more sustainable than a comparably priced series watch.

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”.
In fact, to produce in cycles.
"Through this watch, I try to do my job in a more virtuous way. It aims at pushing the watchmaking industry to question its design and production processes, and consider that changes are needed. And possible.
It is a tribute to the women and men whose work contributes to a better future, and an ode to craftsmanship and the people of watchmaking. A concrete step towards a more sustainable watch industry". Cedric Bellon
