LM Thunderdome (platinum or tantalum)

The MB&F LM Thunderdome triple-axis tourbillon watch was announced December 3, 2019. There are limited edition two versions of this timepiece: 33 pieces in platinum; 10 pieces in tantalum.

World’s Fastest Triple-Axis Tourbillon:

The movement in the LM Thunderdome is the world’s fastest triple-axis tourbillon.

“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.” -MB&F

Caliber Number:

As seen with the innovative designs in their timepieces, it’s clear that MB&F doesn’t color within the lines, they are independent in every sense of the word. This even carries over into the way they designate their calibers. Unlike most brands that use a numbering system, MB&F calls this caliber by the same name of the watch itself. Here is an official explanation in the brand’s own words:

“We never really have any calibre number as every new Machine as its own new movement – and therefore, we give the name of the Machine to the new calibre. For example, this watch is called LM Thunderdome, so the name of the calibre would be LM Thunderdome.. it will never be used in anything else than a LM Thunderdome.” -source: email correspondence

Please allow us to interrupt your gear turning and caliber learning to say thank you. Thank you for being here! Now, back to the movement..

Partnership Project:

The LM Thunderdome’s movement was developed for MB&F by Eric Coudray and Kari Voutilainen.

“The Legacy Machine Thunderdome is a collaboration between MB&F and two legendary watchmakers: Eric Coudray – a legendary innovator from the Vallée de Joux known for his unorthodox, jaw-dropping complication – and Kari Voutilainen – a famed perfectionist and acclaimed pillar of traditional craft based in Môtiers.” –source

Maximilian Büsser (Owner and Creative Director of MB&F) explains the history of this partnership in detail in this video.

MBandF is one of the most horologically supreme watch companies in the world. Patek and Rolex have nothing on masterpieces like this.
