The Kurono Grand Jubilee Calendar Honors Hajime Asaoka’s 60th Year

— October 16, 2025 — Art & Design
The Kurono Grand Jubilee Calendar celebrates master watchmaker Hajime Asaoka’s 60th “Diamond Jubilee” through refined craftsmanship and poetic design. The watch features a salmon guilloché dial inspired by frost-touched leaves and soft winter light over Tokyo. Subdials for day and month are symmetrically arranged beside a recessed date window, balancing visual depth with quiet order. Onyx-black hands and a cabochon crown add contrast, creating a harmony of texture and tone that feels both vintage and modern.

Housed in a 38 mm polished stainless steel case, the design replaces Kurono’s typical coin-edge bezel with a smooth concave profile for a sleeker silhouette. Powered by a Miyota 9122 automatic movement, the piece includes a solid gold medallion engraved with Asaoka’s personal seal on the caseback. Produced in limited quantities, the Grand Jubilee Calendar stands as a tribute to time, artistry, and enduring restraint.
