Magnetic Field Detection Compass

Description

This High-Quality Stainless Steel XL Magnetic Field Detection Compass is an ideal tool to detect if your mechanical watch is magnetized which makes it runs faster than it should be. If so, you will need an electronic demagnetizer device to remove the magnetic fields completely and thus restore its running accuracy.
