Masahiro Kikuno is the first Japanese watch maker to join the prestigious Swiss institution AHCI (Académie Horlogère Des Créateurs Indépendants). He is specialized in the manufacturing of exclusive hand made mechanical timepieces. Born in 1983, Masahiro Kikuno started his watchmaking after graduated from HIKO Mizuno College WOSTEP course. He remained as the teacher of this course.
In 2011, he became the candidate member of AHCI and unveiled the temporal hour watch called “Wadokei” in Baselworld watch fair in the same year. The originality of his watches amounts to what they are made by “hand “. The cutting out of the bridges and the tourbillon cage, and even enrolling the numbers on the dial plate are achieved by hand.

The Perpetual Calendar tourbillon created by Masahiro Kikuno in 2011, boasts the calendar functions such as day, week, month and leap year indications and equipped with a tourbillon mechanism to improve the timekeeping by annulling errors of rate due to gravity. This was for the first time in Japan that an independent watch maker created such a horological complication. Kikuno assembled the parts designed and developed by himself to make the basic manual winding movement(ETA 6997 -1) a set of high complexity. The components of vorticity are also designed and manufactured by hand, whether the bridges, the cage, the spring or wheels, but also dressing as the transparent date disc, the blued and box.
The Japanese style “Temporal hour watch “built in 2011 is the first “Automatic wari-koma dial watch (Wadokei)”, which has automatic index adjusting in each season. “Temporal hour” system is the way of counting hours depends on the time of sunset and sunrise. Hours between sunrise and sunset are divided into 6 and used as one counting unit.
The time of sunset and sunrise varies along the season. So this unit hour changes by season. So, in Edo era, temporal hour clock was very well designed to adjust this unstable time unit system. This “Temporal hour” watch which Mr. Kikuno made was operated under the same system amazingly into small wrist watch world. The space between index will be longer in daytime and shorter in night time on the summer solstice, while shorter in daytime and longer in night time on the winter solstice.
This watch also provided not only temporal hours hand but regular hour hands so that we can find normal time and minutes. The base caliber of “Temporal hour watch ” is Swiss made ETA 6498-1 movement.
