First launched in 2017 – in red gold with a black ceramic bezel, and in titanium with a blue ceramic bezel – the HM7 is back in a titanium case with a green sapphire crystal bezel.
After pushing the boundaries of horological exploration by blasting into outer space (HM2, HM3 & HM6), launching into the sky (HM4), and powering down the road and around the track (HM5, HMX, HM8), MB&F plunges into the water with the Horological Machine N°7, aka HM7 Aquapod.
The organic jellyfish-inspired design of HM7 Aquapod is counter-balanced by the very mechanical horology within: a central flying tourbillon tops the concentric vertical movement architecture, with indications radiating out from the centre like ripple in a pond.
Where jellyfish have a radially symmetric ring of neurons for a brain, the Aquapod has radially symmetric rings displaying hours and minutes. Where jellyfish have a hood or bell on top, the HM7 Aquapod has an imposing flying tourbillon regulating the power generated by the rotor, and transforming it into the display of time.
The curves of the high-domed sapphire crystal are mirrored in the shape of the time display rings, which are mathematically precise, curved spherical segments.
And then there’s the bezel. While the Horological Machine N°7 is not a dive watch, it is a timepiece comfortably at home in the water – so MB&F added the one element that all serious aquatic watches possess: a unidirectional rotating bezel. However, unlike in every other dive watch, here it is not attached to the case, but floats apart like a life buoy.
The HM7 Aquapod began its gestation as a horological jellyfish, and the architecture of its engine is appropriately biomorphic. Where a jellyfish generates power from food caught in its tentacles, the HM7 generates power from its tentacle-like automatic winding rotor. They are crafted from a solid block of titanium; their very three-dimensional nature makes machining and finishing more than challenging. Underneath the tentacles, a platinum mass ensures powerful and efficient winding.
The 303-component, 72-hour power reserve HM7 engine was developed in-house by MB&F. Spherically three-dimensional, all its mechanisms (from the winding rotor at the bottom, past the mainspring barrel and hour and minute displays, to the flying tourbillon on top) rotate concentrically around the center.
And like many jellyfish, the HM7 glows in the dark. It glows where one would expect it to – on the hour and minute numerals – but also around the inside of the movement, to light up that flying tourbillon at night…and in addition, along the tentacle-like winding rotor so that its operation, too, can be appreciated in the dark.
The HM7 Aquapod is limited to 50 pieces. But there are two more limited editions as well: a titanium with blue ceramic bezel and a red gold with black ceramic bezel one.
