Using your Diesel DZ4589 Arges watch is easy. The chronograph function can be used to time events. Just press the side buttons to start, stop, and reset the timer. The three subdials show different time measurements. As for daily use, the watch can handle splashes and short swims thanks to its 50m water resistance, but don't wear it for deep - sea diving. To keep it in top condition, clean the case and bracelet regularly with a soft, dry cloth. Avoid exposing the watch to extreme temperatures or strong magnetic fields, as this may affect its performance. If you have any issues, it's best to take it to a professional watch repair service.
