Advantages of Breitling Mechanical Movements
The mechanical movements give the watches extremely strong resistance to electrical and magnetic disturbances, with an antimagnetic rating of 80,000 A/m. In analog quartz watches, a strong enough magnetic field can depolarize or partly reorient the permanent magnets in the stepper motor. The mechanical movement is for all practical purposes invulnerable to strong electrostatic discharges, RF electromagnetic fields or by Electromagnetic Pulse (EMP), whereas a quartz watch’s CMOS logic chip and stepper motors can be destroyed easily by these. The automatic winding mechanism also gives much better low temperature operational capability than an electronic watch. Breitling chronometers are typically well armored and pressure resistant with synthetic sapphire faces to further withstand shock and high pressures.
