The Legacy Machine Thunderdome from MB&F

When master watchmakers Eric Coudray and Kari Voutilainen came together, a legacy was created.

The Legacy Machine Thunderdome from MB&F is the culmination of four years of development and an unprecedented collaboration between two of the most admired horological minds today. 

While the technical construction originated with Coudray, it was Voutilainen who translated the mechanism into the aesthetically refined movement that inhabits LM Thunderdome.

The complex and delicate relationship between the 413 components of the LM Thunderdome engine makes every micro-adjustment an extended exercise in mechanical reconfiguration. 

With a movement diameter of only 35mm, proportionate design is exponentially emphasised and there is far less margin for error. 

A bridge that is even one single millimetre too wide, or a pinion moved just a few micro-metres to either side, would immediately stand out, glaringly out of place.

Voutilainen, said: “In such a complex project, with so many different considerations, I chose the traditional method of hand-drawing the movement rather than working with computer software. 

It allowed me to have a much better feel for the proportions and the choices that needed to be made about aesthetics and function.”


MB&F founder Maximilian Büsser says, “One of the many things that makes me incredibly happy about this piece is that we got to bring together two people I adore in this industry; who are incredibly talented, have completely different styles and personalities, and have never had the chance to work with each other”.

The watch comes in two limited editions. The first version of 33 pieces in platinum with a light blue guilloche dial and the seconds limited to 10 pieces in tanalum for the hourglass (5 pieces with an aventurine dial and 5 pieces with a dark blue guilloche dial. 

The watch features a regulating mechanism featuring 3 fast rotation axes revolving at different speeds and on different planes. The rotation speeds of the axes starting from the centre are respectively 8 seconds, 12 seconds and 20 seconds. The combined weight of the multi-axis mechanism is nearly 1g.

413 components and 63 jewels make up the watch with sapphire crystals on top and the display back are treated with anti-reflective coating on both faces.

blue hand-stitched alligator strap with platinum or tantalum folding buckle is included which matches the case.

The Legacy Machine Thunderdome starts at $280,000 USD.
