The MB&F LM2 Palladium (Legacy Machine No. 2) is an offspring to the Legacy Machine series with a palladium case
Chemical element Palladium (Pd) is a silvery-white metal discovered in 1803. Together with platinum, rhodium, ruthenium, iridium and osmium it forms a group of elements called Platinum Group Metals (PGMs).
.
Palladium has a Vickers hardness of approximately 150 to 250 HV, depending on its purity and any specific alloying elements. This hardness makes palladium a durable choice for watch cases, as it resists scratching and wear while also being lightweight and hypoallergenic.

Watches from palladium
Although the Rotonde de Cartier collection counts more than 60 different models there isn’t a skeletonized model with “mysterious hours”
