Shock Resistance The pulling of objects toward the center of the Earth by gravity is called G force and is it a measurement of acceleration. The force of gravity while you are sitting or standing is considered 1 G. As you pull more Gs, such as when jumping up and down or when riding on a roller coaster, your weight increases correspondingly. A 10-pound human head will weigh 90 pounds under 9 G acceleration.
Built with the highest of quality standards in mind, every BALL watch has undergone rigid testing procedures to verify shock resistance. This is especially true of the unmatched standards of the Engineer Hydrocarbon series, rated up to 7,500 Gs. According to the International Standard (ISO 1413), the shock resistance test is conducted using a pendulum impact-testing machine. The mechanism sets off a circular movement which brings the pendulum to hit the watch from 1 meter. The first shock is directed against the side of the case, parallel to the plane of the watch, on the 9 o'clock side. The second shock is directed against the glass, perpendicular to the plane of the watch.
At Ball Watch Co., we go beyond the above standard by hitting with a tougher 1.5 meter hammer strike and adding a third shock directed against the relatively weaker 3 o'clock crown position of the watch. The Hydrocarbon must pass the test without any damage. Finally, the sapphire glass used in the Engineer Hydrocarbon collection is specially made 4mm thick for better protection.
