Louis Moinet's first hour-strike watch, a timepiece with a mechanism that chimes each passing hour on the hour with the appropriate number of chimes. Debuted to coincide with the 250th birthday of company namesake Louis Moinet, the Louis Moinet Ultravox shows off its complex chiming mechanism by placing it in plain sight directly on the dial.
The result is a 46.5mm rose-gold-cased watch that allows the wearer to enjoy the chiming mechanism’s hourly dance. The wearer can watch as the central independent seconds hand triggers a system arming the hammer at twelve o’clock to then strike out the hours on a gong circling the movement. A silencer mechanism allows the wearer to disengage the chime if desired.
Louis Moinet enlisted the talents of the Gaïa Prize-winning watchmaker Eric Coudray to design the Ultravox. Coudray’s team had to design a special plate with more than fifty jewels to engage the chime mechanism’s various components, many of which are finished in “Moinet blue” to showcase the acoustic mechanism. The rear of the Ultravox reveals a system with darkened, parallel double rotors. One serves to generate force for the hours and minutes mechanism, while the second rotor is fully employed to power the chime.
