[Pay attention to the unique toughness structure of the ball watch]
The commitment to shock-resistant performance can be felt in the uniquely designed double-door folding buckle (left photo). Once locked, it can withstand a load of 1400 Newtons (about 140 kg weight) and has a heavy design that has passed 5,000 opening and closing inspections. In addition, the two thin pins that secure the buckle are machined from a block of stainless steel to ensure uniform strength, minimizing the risk of the pins breaking. In addition, the parts that connect the case and the bracelet are not fixed with a single spring rod, but a “two-point fastening (right photo)” that is fixed with two screw-type pins. In the event of an emergency, the possibility of putting on and taking off the watch or falling off the watch has been thoroughly devised in every detail.
