In-Depth: MB&F; LM Thunderdome Triple-Axis Tourbillon
The flying tourbillon wristwatch for women – the Legacy Machine FlyingT – that MB&F; launched last year foreshadowed its latest watch – the Legacy Machine Thunderdome, boasting the fastest ever triple-axis tourbillon developed by independent watchmaker Eric Coudray. No doubt multi-axis tourbillons are hardly new, especially after Jaeger-LeCoultre unveiled its first Gyrotourbillon in 2005 – which was also developed by Mr Coudray – but the LM Thunderdome takes the concept further by every metric, primarily by building on past ideas to achieve higher cage velocities than ever before. Most intriguingly, the Thunderdome movement incorporates a tourbillon lever escapement first devised by Albert H. Potter – a talented American watchmaker who worked in Geneva in the late 19th century – as well as an unusual multi-axis tourbillon that utilises a carrousel for its outermost cage, christened the TriAx. The ingenious construction of the tourbillon is thanks to Mr Coudray, who now runs complications workshop TEC Ebauches and is best known for the numerous exotic tourbillon movements he has developed. After his two-decades at Jaeger-LeCoultre where he became the resident technical genius, Mr Coudray worked for several brands of varying levels of credibility, including at Cabestan where he perfected its vertical tourbillon, and more recently at Cecil Purnell, where he created the Spherion tri-axial tourbillon, which has a similar construction to the Thunderdome.
