SPB469J1 PRESAGE watch Automatic open heart

The “open heart” pair, SPB469 and SPB471, feature dials with a radial finish modeled on raw silk thread in Shiro-Iro (creamy white) and Sumi-Iro (gray-black), respectively. These reveal the balance wheel in a window at nine o'clock, while the subdial at six o'clock is a 24-hour display that is synchronized with the hands.
