Our factory direct promise
The CB x ACE 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.
Red GMT arrow-hands are iconic. On dashboard instruments, manometers and tools, the red 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”.
In fact, to produce in cycles.
"Through this watch, we encourage all industry participants to do better for their next watch by using an objective and measurable sustainability index to measure their production. If we all work on improving the same measurable sustainability index, change will become a reality.
This watch 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.
Our wish is that the Swiss made label will one day include a minimum sustainability score".

“As a long-time watch collector I immediately fell in love with this piece. What really stood out for me, is the circularity & sustainability aspect. I never realized that the watch industry is rather lagging in making their processes more “green”. I really enjoyed the open letter Cedric and Alon have written and it made me want to have a watch with a sustainability score in my collection!”
