The Armin Strom Gravity Equal Force Ultimate Sapphire Purple blends intricate mechanics with a vibrant purple design. This edition features a unique guilloché-engraved purple mainplate by Kari Voutilainen, marking a departure in color for the brand. The timepiece is part of the System 78 collection, which perfectly incorporates Armin Strom’s innovative haute horlogerie approach while maintaining classical watchmaking elements. Notably, the Gravity Equal Force features an equal force transmission mechanism, ensuring consistent precision and autonomy. Entirely manufactured in-house, the watch is hand decorated, with polished bevels, black polished screws, perlage, and Geneva stripes. Its distinctive dark grey ruthenium-plated bridges, inspired by pocket watch designs, undergo the same processes. The Gravity Equal Force Ultimate Sapphire Purple is limited to 25 pieces per year.
