Independents

Masahiro Kikuno - An extensive overview

 

Born on February 8, 1983 in Hokkaidō, Japanese watchmaker Masahiro Kikuno is one of the most original and unique independent creators.

He became the youngest member of the AHCI (Académie Horlogère des Créateurs Indépendants) and the first Japanese full member, at age 30.

H/ SO - 2024

Powered by a Seiko cal. NH34A with uniquely designed celestial display module, the constellation disk represents the starry sky as seen from the ground at 35 degrees north latitude. 

North is at 12 o'clock, West at 3 o'clock, South at 6 o'clock, East at 9 o'clock, and Polaris at the center of the dial, rotating counterclockwise in a cycle of approximately 23 hours 56 minutes.

Named “SO”, meaning “blue” in Japanese, Kikuno refers to the cursive script or grass script in East Asian calligraphy, which is also pronounced “So”.

About this piece unique, Kikuno explains, “I made this watch for myself because I wanted a watch that could be used in a relaxed manner without being overbearing. I don’t have any plan to produce this watch in the future.”
