Mechanical watches are delicate pieces of machinery that can be thrown off kilter if the proper precautions aren’t taken. Magnetic fields, extreme temperatures, and shocks are among the risks watches face. Below, in this list we take a look at some watches designed to withstand these outside factors.
The Jaeger-LeCoultre Master Compressor Extreme LAB 2 has a safety band around its hairspring, limiting the motion of the spring when the watch receives a shock. The watch also has two screws to hold the hairspring stud. The hairspring itself is made of silicon and weighs only one-third as much as a conventional metal hairspring. It is therefore less vulnerable to shocks. Jolts are also buffered by the case, which combines an inner container and exterior housing, both made of the titanium alloy TiVan15.
The Omega Seamaster Aqua Terra >15,000 Gauss became the world’s most magnetism-resistant watch, exceeding the level of magnetic field resistance of other pioneering antimagnetic watches such as the Rolex Milgauss, when it was introduced in 2013. The key to this milestone is its innovative movement, Omega Co-axial Caliber 8508, which is made up largely of non-ferrous components such as silicon balance springs and nickel phosphorous escape wheels.

For its Monaco Twenty-Four Calibre 36, TAG Heuer developed what it calls an Advanced Dynamic Absorber System. The movement is suspended at all four corners inside the square case. Four plastic buffers protect the movement against shocks and especially against vibrations in the frequency range of one to 10 Hz.
The IWC Pilot’s Watch Double Chronograph protects its movement from the effects of magnetic fields with a “Faraday cage,” and inner case of soft iron around the movement.
