Platinum makes its debut in HM7, its bright silvery-white hue an emphatic counterpoint to the vividly crimson unidirectional rotating bezel. Used for the first time in any MB&F creation, red is not a colour that immediately comes to mind when thinking of marine life — but it has a very particular significance when it comes to the jellyfish.

The deeper you go in the ocean, the less colour you see. Red is the first colour to disappear, being on the lowest end of the visible light spectrum and thus most easily absorbed by water. This is why you find a higher concentration of red sea creatures in the deepest waters — being red makes them almost invisible to predators.

HM7 Aquapod Platinum Red comes from the deepest recesses of the horological ocean, with free-floating numerical appendages and unprecedented transparency surrounding its beating heart: a 60-second flying tourbillon.

Unlike previous incarnations of Aquapod, which indicated the hours and minutes via rotating rings with transferred numerals, HM7 Platinum Red features three-dimensional numerals sculpted in titanium. The metal was specifically selected for its lightness, in order to have as little additional marginal load on the engine as possible. However, this mechanical advantage came at a cost, since titanium is exponentially denser and stronger (which is to say, harder to machine) than the aluminium that made up the time-indication rings on previous Aquapod versions.

The stems attaching the hour and minute numerals to their respective mounting rings are rendered black with a coating of DLC (diamond-like carbon), completing the ethereal floating effect that one associates with the sight of a jellyfish drifting with the ocean currents.

One of the most startling visual aspects of a jellyfish, almost alien in how far it is from the mammalian systems with which we are familiar, is its transparency. How can something so diaphanous and seemingly insubstantial be alive? HM7 Platinum Red homes in on this point, replacing the battle-axe tourbillon bridge of previous Aquapod versions with a clear sapphire component. The flying tourbillon of the HM7 engine is revealed like never before, highlighted by a halo of high-luminosity AGT.

Because, of course, HM7 Platinum Red is aglow with luminescence, just as any fascinating creature of the deep should be. Apart from the AGT ring surrounding the flying tourbillon, luminous material is found in the laser-engraved markings of the unidirectional rotating bezel and on the surface of the hour and minute numerals. These are untinted Super-LumiNova, which fluoresce white after exposure to light.

The self-winding, 391-component engine of HM7 Platinum Red was developed entirely in-house at MB&F.

The HM7 Platinum Red is presented in three versions, with three interchangeable straps (red, white and black) in aircraft-grade rubber.

Whereas the majority of watch movements are constructed on a lateral plane to be as flat as possible, the HM7 engine goes up, not out, with all of its components arranged vertically. The movement of HM7 was entirely developed in-house by MB&F.

From bottom to top, the winding rotor, mainspring barrel, hour and minute indications, and 60-second flying tourbillon are all concentrically mounted around the central axis. Energy travels from the rotor at the very bottom of the movement to the flying tourbillon at the very top via staggered gearing that allows mainspring torque to be transmitted from one level to the next.

The case of HM7 Aquapod is basically a three-dimensional sandwich comprising two hemispheres of high-domed sapphire crystal on either side of a metal case band. The unidirectional bezel floats outside the case proper, while dual crowns are located between the two structures.

The new HM7 Platinum Red will be made in a limited series of 25 pieces.
