Vincent Calabrese NHC FYS NHC.FYS.231AD is an elegant women's watch that suits any style or occasion, be it formal or casual. The Fly’Ora series indicates the time in a traditional way, while employing an ingenious complication that reveals a new butterfly with each new hour. This jump-hour mechanism, while telling us the time, also takes us on a poetic journey through nature, thereby effecting the complex combination of two masterful techniques of the watchmaker’s art.
