Armin Strom Gravity Equal Force, in rose gold
Armin Strom completes its Gravity Equal Force collection in 18K rose gold. Kari Voutilainen cuts the grain d’orge guilloché pattern on the mainplate by hand, beneath a sapphire dial that seems to float.
Armin Strom today introduces the Gravity Equal Force “Ultimate Sapphire Rose Gold”, which the brand calls the top-line piece of the collection. Rose gold-coloured bridges and a brown mainplate sit beneath the dial, off-centre and grey-toned.

The full 18K rose gold case measures 41mm across, on a brown nubuck strap with beige stitching. The mainplate’s grain d’orge pattern is cut on a traditional hand-operated guilloché machine, so its lines catch the light differently from every angle.
Armin Strom says the automatic Calibre ASB19 was the first movement to combine a stop-work declutch with a Geneva cross inside the barrel. The design delivers equal force to the regulating organ from start to finish, and a micro-rotor sits opposite the barrel, keeping the view of the movement clear. Armin Strom keeps annual production small, so each rose gold piece stays close to the hands that finished it.
