Magnetism is one of the leading causes of inaccuracy in automatic watches, as magnetic fields can cause the hairspring to stick, leading the movement to run fast or stop entirely. In a luxury watch safe, where multiple electric motors operate in close proximity to sensitive timepieces, WatchMatic utilizes individually shielded motors. This specialized engineering uses ferromagnetic enclosures to redirect magnetic flux away from the watch, ensuring that even high-performance movements remain unaffected by the electromagnetic fields (EMF) generated during the winding process.
The Invisible Threat to Your Balance Spring
Through years of observing automatic movements, we’ve seen countless owners struggle with watches that suddenly gain minutes per day. The culprit is almost always magnetism. A watch doesn't need to touch a magnet to be affected; just being near an unshielded electric motor is enough.
Based on our engineering standards at WatchMatic, we understand that every electric motor inherently creates a magnetic field. In a multi-rotor safe, these fields can accumulate, creating a "magnetic storm" inside your security cabinet. This is why standard, low-cost winders often do more harm than good to a delicate Patek Philippe or Audemars Piguet.
Engineering the Solution: Individually Shielded Motors
At WatchMatic, we’ve found that the only professional way to neutralize this threat is through "Shielded Technology."
- Zero-Magnetism Design: Each of our rotors is powered by a Japanese Mabuchi motor encased in a shielding alloy. This prevents magnetic leakage from reaching the watch cradle.
- Faraday-Like Protection: The shielding acts as a barrier, ensuring that the magnetic flux remains contained within the motor's housing.
- Precision Testing: Every batch of our watch winder safes undergoes Gauss meter testing to ensure that the magnetic output at the watch position is effectively zero.
Why it Matters for High-Capacity Safes
When you have a safe holding 12, 24, or even 36 watches, the density of electronics is high. Through our experience with luxury horology, we know that collectors often store their most complicated—and sensitive—pieces in these safes. Without individual shielding, the collective EMF from dozens of motors would eventually magnetize every watch in the cabinet.
By choosing a WatchMatic solution, you are not just buying a theft-proof box; you are investing in a controlled environment where mechanics and magnetism never collide.
