Masahiro Kikuno

Masahiro Kikuno was born on February 8, 1983, in Fukagawa, Hokkaido, Japan. He served in the Japan Self-Defense Forces before leaving in 2005 to enroll at Hiko Mizuno College of Jewelry (commonly called the Hiko Mizuno Watchmaking School) in Shibuya, Tokyo, where he studied a WOSTEP-affiliated watchmaking curriculum, graduating in 2008. Reports differ on whether the program itself ran three or four years, but the curriculum focused first on repair rather than original construction; he went on to work at the school for several years after completing his studies.

Kikuno founded his own workshop and produced his first Wadokei-inspired watch in 2011, reinterpreting the traditional Japanese temporal-hour clock, which divided daylight and night into variable-length hours, as a modern wristwatch mechanism. He became a member of the Academie Horlogere des Createurs Independants, an international association of independent watchmakers, joining the small group of makers recognized for building complete movements largely by hand. He works from a compact workshop converted from rooms in his own home in Matsudo, Chiba Prefecture, producing roughly one watch a year. He presented work at Baselworld in 2012. As of mid-2026, recent media appearances and social media posts describe him actively working, and no death or retirement has been reported.

Specialist watch press, including Fratello, Europa Star, and WatchProSite, consistently frames Kikuno as a leading figure in Japanese independent watchmaking, praised for building movements almost entirely by hand and for reviving the wadokei tradition of variable-length hours in wristwatch form. Coverage of his 2024 Phillips result described it as a record-setting debut for his work at international auction. No exact, attributable critical quotes from named critics at major outlets could be confirmed for reproduction here.

Kikuno's market has operated almost entirely outside the conventional gallery or dealer system. According to Europa Star, he produced and sold about 20 watches between 2012 and 2024, priced between roughly JPY 5,000,000 and JPY 18,000,000 (about USD 32,000 to 115,000 at 2024 exchange rates), all sold directly to clients on order, with his order books closed as of that reporting. His first appearance at international auction came at Phillips' TOKI sale in Hong Kong on November 24, 2024, a themed sale dedicated to Japanese watch collecting, where a unique pink gold Tourbillon 2012, the first watch he ever sold, sold for HKD 2,286,000 (about USD 293,751), achieving nearly six times its pre-sale high estimate according to Phillips. No later or higher public auction result for his work has been documented as of this writing.

There is no catalogue raisonne for Kikuno, and he is not represented by any gallery; verification of a piece rests on the artist's own workshop records, commission documentation, and his AHCI standing. His production is extremely small, on the order of one finished watch a year, and his single confirmed auction result to date is a solitary data point rather than a track record, so it should be treated with caution rather than extrapolated into a price trend. Collectors should also note that Kikuno operates as an independent horological maker rather than a painter or sculptor in the conventional gallery-market sense, which changes how provenance, authentication, and resale typically work for his pieces.
