This timepiece is equipped with automatic caliber 6R5H, which boasts a 72-hour power reserve. The three-ball movement includes a 24-hour display on a dedicated subdial, a stop-seconds function and a manual winding option, with water resistance guaranteed up to 5 bar.

The distinctive tonneau-shaped stainless steel case, treated with a special scratch-resistant coating, measures 35.90 mm wide by 12.53 mm thick. The double-curved sapphire crystal with anti-reflective coating protects the dial, while the transparent case back reveals the inner mechanics.

For the first time, the tonneau case is paired with a stainless steel bracelet with deployment clasp, designed to offer superior flexibility and comfort on the wrist.

The dial in fine white enamel, worked entirely by hand, is distinguished by Roman numerals that harmoniously follow the curved lines of the case. The purity of the enamel and the arrangement of the spheres give the watch a refined aesthetic, capable of combining Japanese manufacturing tradition with a distinctive contemporary design.

Watch accompanied by official Seiko warranty and packaging.
