When you combine the names MB&f, Eric Coudray and Kari Voutilainen in one project the result is simply out of this world. The new MB&F Legacy Machine Thunderdome is the first-ever collaboration between legends Eric Coudray and Kari Voutilainen and the birth of a totally new proprietary ‘TriAx’ tourbillon mechanism that features 3 axes revolving at different speeds and on different planes, in record-breaking 8 seconds, 12 seconds and 20 seconds. Additionally, the Legacy Machine Thunderdome offers the first-ever combination of Potter escapement, hemispherical balance, and helical hairspring.
