Every order includes your own Tree Passport with information about where your tree was planted, the tree species and the project it belongs to.

No two walnut grains are ever the same, so each bracelet and pendant in this set is subtly unique. Paired with deep black marble, the design blends natural elegance with modern precision, resulting in a piece that looks as timeless as it feels.

Join us on our journey to plant 10,000 trees — and see how your watch creates real, lasting change: one tree, one family, one future at a time.
