A short while ago MB&F unveiled their fifth ever Performance Art piece – the MOONMACHINE – a mini-event that has completely obliterated any previously held perceptions I had of what the concept of ‘cool’ actually encapsulates. A HM3 Frog complete with Stepan Sarpaneva moon-face moon-phase complication? Now that is cool!

Performance Art
In the past MB&F has worked with jewelers (how could you forget the stunning JWLRYMACHINE created in conjunction with Boucheron?), watch designers (the HM2.2 by Alain Silberstein) and others to create their unique Performance Art pieces but never with another watchmaker. That is until now.


This latest addition – and one that is quickly becoming my favorite of the collection – is the result a highly successful collaboration with Finnish watchmaker Stepan Sarpaneva, and is the first ever to endow a Horological Machine with a new complication. Based on Sarpaneva’s own face the distinctive moon-face moon-phase complication has achieved almost a cult following amongst dedicated fans of the brand and can be found in one variation or another on many of his watches.

The quality of finishing is superb but what I really love about the design however is its unique ability to imbue the timepiece it adorns with a real sense of character. Even though in my mind the HM3 is already such a distinctive timepiece the effect of adding the moon-face almost makes me feel like I am discovering a new piece for the first time. I know that may sound strange or hard to believe for some of you, especially as we have already seen several iterations of the HM3 before, but I encourage you to watch the video below before you make your mind up for sure.

The slow orbit of the two moon-faces is mesmerizing and the size and openness of the rotor window lends itself marvelously well to the display of this complication. Adding an extra element to the astrological theme the winding rotor, made from a steel and 22k gold disc, has been decorated with laser-pierced stars, forming the stars and constellations visible in the northern sky. As you can see in the video above the subtle effect of its movement only serves to further enhance that sense of animation and life that the Sarpaneva moon-face brings.


The new MOONMACHINE is available in three limited editions of 18 pieces each: titanium case with white gold moon faces in a light blue sky, black titanium case with white gold moon faces in a dark blue sky and red gold case with red gold moon faces in an anthracite sky.

The Final Word
Like I said at the start, MB&F and Sarpaneva together? Now that’s cool!
