The new Gravity Equal Force in 18-carat rose gold

After the resounding success of the first model in steel, the edition has now been expanded to include an 18ct rose gold watch with a black alligator leather strap.

The black dial imbues this remarkable timepiece with an elegant retro character and accentuates the new design of the watch with striking contrast.

Gravity Equal Force is the latest watch to incorporate the Armin Strom basic principle: always keep innovating.

This watch changes the traditional mainspring barrel by adding a “stop-work release mechanism” in combination with automatic winding to deliver constant force.

With the redesign of the timepiece, dial and case, Gravity Equal Force marks the launch of the new System 78 collection: innovative timepieces for a competitive price.
