Independent brand MB&F has introduced a new limited-edition version of the HM7 Aquapod, now with a titanium case and an electric-green bezel. The Aquapod was first released in 2017 and combined an annular design inspired by a jellyfish with dive watch elements and a flying tourbillon.

The HM7 Aquapod was first introduced in 2017

The unidirectional bezel construction from the original Aquapod was one of its highlight features. It isn’t attached to the watch itself at all; instead, it floats freely above the dial resembling a life buoy. In order to reach the ideal tint for the bezel, a sapphire crystal ring was inserted inside of it. Then the numbers and indices were metalized under the sapphire crystal, along with a layer of green lacquer.

The humble jellfish served as the inspiration for this diver

The watch’s three-dimensional movement architecture, while very avant-garde compared to most of today’s flat, horizontal versions, actually has its roots in the “onion” pocketwatches popular in the 18th century. Developed entirely in-house, the movement of the HM7 features a winding rotor, mainspring barrel, hour and minute indicators, and flying tourbillon, all concentrically mounted around a central axis and rotating concentrically around it.

The movement contains 303 components

Energy generated by the tentacle-like rotor at the bottom travels up to the tourbillon regulator at the top via a series of gears that allow the power to transition from level to level in the manner of climbing stairs. The three-dimensional rotor is crafted from a solid block of titanium, with a heavy platinum mass underneath the tentacles to ensure powerful winding.

The tourbillon regulator, positioned as the “hood” that protects the ring of neurons that serves as the jellyfish’s brain, is surrounded by the hours and minutes displays, on two concentric, spherical segment disks, made of aluminum and titanium, supported by extra-large ceramic ball bearings and rotating with a very low coefficient of friction. All in all, the movement contains 303 components and holds a 72-hour power reserve.

This is no shrinking violet on the wrist

The case — which measures 53.8 mm in diameter and 21.3 mm thick — has been described by MB&F as a “three-dimensional sandwich, with two hemispheres of high-domed sapphire crystal on either side of a metal case band.” The crown on the left is to wind the movement, while the crown on the right is used to set the time. The MB&F HM7 Aquapod is limited to 50 total pieces and is priced at $108,000.
