#Repost @osterwatches with @repostapp ・・・ Video showing the #MirroredForceResonance by #ArminStrom in action. Superb movement concept created by #masterwatchmaker Claude Greisler. The concept of Resonance in timekeeping was first explored in the mid-1600s by famed Dutch watchmaker Christian Huygens. #breakthrough #complicatedwatches #watchesofinstagram #limitededition #osterjewelers #osterwatches #collectible
