This is usually indicated by a running second hand with a luminous tip or tail. Magnetic resistance. This is tested by 3 expositions to a direct current magnetic field of 4,8. A/m. The watch must keep its accuracy to ± 3.

Shock resistance. This is tested by two shocks (one on the 9 o'clock side, and one to the crystal and perpendicular to the face). The shock is usually delivered by a hard plastic hammer mounted as a pendulum, so as to deliver a measured amount of energy, specifically, a 3 kg hammer with an impact velocity of 4. The change in rate allowed is ± 6. Chemical resistance. This is tested by immersion in a 3. Na. Cl solution for 2.

This test water solution has a salinity comparable to normal seawater. Strap/band solidity. This is tested by applying a force of 2. N (4. 5 lbf) to each spring bar (or attaching point) in opposite directions with no damage to the watch or attachment point.
