The Hidden Force Behind Timekeeping
Every wristwatch tells a story of craftsmanship, engineering, and precision. While most of us admire the smooth sweep of the hands or the elegance of a case design, very few stop to think about the invisible forces driving that precision. One of those unseen heroes is the magnet.
Micro-Magnets™ are designed to deliver extraordinary strength in incredibly small sizes. Measuring as little as 0.010″ in diameter yet producing magnetic energy up to 52 MGOe, these components are made with tolerances as tight as ±0.0003″. For watchmakers, this means they can rely on a consistent, powerful part that fits into even the most compact movement.
Meeting the Watchmaker’s Challenges
Watchmaking presents a unique set of challenges: extremely limited space, high demands for precision, and a need for long-lasting performance. Micro-Magnets™ meet these requirements.
- Compact strength: Powerful magnetic force even at microscopic dimensions.
- Durability: Protective coatings, including biocompatible options, extend longevity and improve assembly.
- Consistency: Precision tolerances ensure every part functions as expected, watch after watch.
These advantages make Micro-Magnets™ an invaluable tool for designers and engineers working in the horology space.
How Do Micro-Magnets™ Drive Quartz Movements?
Quartz watches are known for their accuracy, and micro-magnets are at the heart of how they work. In a stepper-motor movement, a permanent magnet acts as the rotor.
Each time an electrical pulse is sent through the coil, the magnet rotates exactly 180 degrees. The next pulse reverses the rotation, creating a steady rhythm. This precise movement is what ultimately powers the gears and keeps the hands ticking at the correct pace.
Without strong yet compact magnets, this delicate process wouldn’t function as smoothly. Micro-Magnets™ ensure that quartz watches deliver the level of reliability that wearers expect, day after day.
Support for Mechanical & Automatic Watches
Although quartz timepieces rely most heavily on magnets, mechanical and automatic watches also benefit from magnetic components. In these designs, Micro-Magnets™ are used for stabilizing tiny arbors, assisting balance wheel regulation, and providing consistent force in areas where space is extremely limited.
Their strength-to-size ratio allows engineers to maintain the traditional beauty of mechanical movements without compromising performance. For luxury brands, this balance between tradition and innovation is essential.
