A unique interpretation of ALTO’s ART01 initial model, crafted in brushed Grade 5 titanium and finished with a DLC coating. It showcases a new expression of ALTO’s innovative savoir-faire: sculpted stone marquetry, this time brought to life through a Bull’s Eye dial.
First introduced in 2025 with a Falcon’s Eye limited edition, this technique offers a groundbreaking visual experience, pushing the boundaries of contemporary watch dial aesthetics.
The first technical challenge lies in selecting stone blocks with sufficient thickness to accommodate the dial’s architecture. Each block must then be sliced into flawless sheets, free of inclusions, while preserving the mineral richness and natural character of the stone. This demanding initial step is essential to the entire process.
The second stage involves machining the stone into six individual segments, each following ALTO’s signature dial design. This unprecedented relief machining requires extreme precision, given the fragility and exceptional thinness of the stone, as well as the complexity of the pattern. The resulting dimensions push the boundaries of what has previously been explored in watchmaking and jewelry.
Finally, each stone segment is meticulously hand-polished, a painstaking process requiring exceptional attention to detail to preserve the purity and precision of the design. The result is a spectacular architectural dial, in which the stone gradually deepens in color toward the center, evoking the natural depth of a bull’s eye — its pupil and iris captured in stone.
