‘STRUCTURE’ Chronograph S1

"How should a chronograph be designed as a true, uncompromising tool watch? 

The Kurono ‘Structure’ Chronograph S1 is my definitive answer, as a product designer, to what a tool chronograph should truly be."

STRUCTURE Series: A New Style Of Tool Watch

"Until now, the Kurono Tokyo watches I have created were designed from my dual perspective as an independent watchmaker and a product designer. 

Their designs were rooted in the formal beauty cultivated over the long history of watchmaking, while incorporating a modern touch suited to contemporary timepieces.

The new Kurono Chronograph S1 raises the purity of product design even further, packing tool-watch functionality into a slightly larger 40mm case."

"The dial utilizes a unique four-layer structure that minimizes the gap between each hand and index as much as possible to maximize legibility. In particular, the chronograph hand has almost zero parallax relative to the indices, allowing it to fully demonstrate the accuracy of a high-beat chronograph.

Additionally, the subdials have been enlarged to their utmost limit, and the counter hands feature a matching fluorescent orange color that resonates with the chronograph hand."

"My design ethos for this project can be distilled into two words: Functional Elegance."
