The subtle force of a magnet has always intrigued me. Almost imperceptible from a distance, it reveals its full strength only at the last moment, snapping into place. This inverse relationship between distance and force is the principle that makes a magnetic clasp so satisfying to use.
My design hinges on this principle. The key was designing a precise, controlled distance between the clasp and the watch case. The precision manufacturing (Entry 4) and the use of VC-150 steel (Entries 3 & 8) played a crucial role here.
This synergy of material and method allowed for a clasp that is safe to wear and not dangerous for the movement. Problem solved. Or so I thought.
While solving this challenge, I became aware of the invisible fields that saturate our modern world. Protecting the movement only from the clasp’s own influence felt wrong.
So, I made a final decision: to shield the Peseux 7001 movement not just from itself, but from the outside world. To do this, I integrated a thin Permalloy foil to the inside of the case-back. This specialized material acts like a shield, redirecting the magnetic field away from the movement.
Protected from these invisible forces, the movement is safe to keep on telling our stories through time.
