In 2014, Armin Strom launched the Skeleton Pure 'Elements' collection. This line showcases the brand's signature openworked design, but the Skeleton Pure takes it up a notch with its fully skeletonized ARM09 caliber, tailored to the specific theme of each limited edition. The 'Fire' edition (reference RG15-PF.5N) stands out with its dark brown PVD coated bridges and sapphire dial ring. The case is crafted in rose gold.
