Hajime Asaoka’s Tsunami Édition Blanche refines the white dial

Hajime Asaoka’s Tsunami Édition Blanche gives the watchmaker’s established time-only model a white, layered dial. Stylised numerals, a striped centre and a recessed small-seconds display provide detail without overwhelming the 37mm steel case. Polished hands and a stepped bezel reinforce the deliberately classical outline.

Inside sits Asaoka’s hand-wound movement with an oversized balance architecture, an approximately 40-hour reserve and a frequency of 18,000 vibrations per hour. A sapphire back exposes the decorated bridges. MONOCHROME profiled this edition in April 2026 and reported it as sold out. The entry describes that edition and does not imply that new order slots are available.
