The Kurono Tokyo Structure Chronograph S1, designed by independent watchmaker and product designer Hajime Asaoka, takes a distinctly functional approach to chronograph design. Housed in a 40mm case, it features an innovative four-layer dial construction that minimises the distance between the hands and indices, reducing parallax and maximising legibility. The enlarged sub-dials, paired with fluorescent orange chronograph and counter hands, further enhance readability while adding a purposeful visual accent. Rooted in Asaoka's philosophy of Functional Elegance, the Structure Chronograph S1 brings together precision, clarity and contemporary tool-watch aesthetics.
