Limited edition of 50 numbered pieces

I designed the Cosmic White Carbon GMT in my workshop in Toulouse, a watch like no other, limited to 50 numbered pieces.

The dial of the Cosmic White Carbon GMT is adorned with the "Petite Tapisserie" motif, an emblematic symbol of the art of watchmaking that blends technical complexity with refined aesthetics. Composed of hundreds of small truncated pyramids on a background of tens of thousands of small diamonds, this unique design plays with light to offer exceptional depth and brilliance to the dial.

The GMT hand features a "Galaxy" color, obtained through physical vapor deposition, a technique that creates a stunning and singular visual effect for each watch, thanks to the random nature of the process.

The exclusivity continues with an elegant engraving on the back of each watch, displaying space-inspired motifs and underlining the uniqueness of each piece thanks to a specific numbering for each watch.

Finally, the forged carbon bezel insert adds a technical and aesthetic dimension, making the Cosmic White Carbon GMT an adventure-ready watch designed for those who appreciate enduring elegance and uncompromising performance.
