Masahiro Kikuno Perpetual Calendar Tourbillon
Created by Masahiro Kikuno in 2011, the Perpetual Calendar Tourbillon watch boasts the calendar functions such as day, week, month and leap year indications and equip 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 complex horological complication. To create the Perpetual Calendar tourbillon complex movement, Kikuno modified an ETA 6997 -1 manual winding movement by incorporating in-house designed and hand crafted components.
