And then there's that bezel. While Horological Machine No.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 every other dive watch on the planet, Aquapod's bezel isn't attached to the case, but floats apart like a life buoy. 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 centre.
The curves of the high-domed sapphire crystal are mirrored in the shape of the time display rings, which are not simply flat and angled, but are mathematically precise, curved spherical segments. And, like many jellyfish, HM7 glows in the dark. It glows where you 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.
