MB&F – HM3 Frog X

Two globular “eyes” that rotated to give the hours and minutes. A widely grinning “mouth” revealing the occasional bright flicker of the signature MB&F battle-axe rotor as it swept past a date scale. A glistening “skin” of titanium, red gold or exotic zirconium. HM3 Frog may have been small as a specimen of amphibious pondlife, but it was mighty on the wrist as it leapt to iconic status at the crossroads of kinetic art and horology.

Now, 10 years after its debut, HM3 Frog makes its comeback, radiantly exposed in a sapphire crystal case, yet still with a hidden message to be discovered. Presenting Horological Machine N°3 “FrogX”.
