Using your Longines Conquest watch is easy. To set the time and date, simply pull out the crown and turn it. You can set the hours, minutes, seconds, and date with a few simple turns. For daily use, just wear it on your wrist and enjoy its stylish look. When it comes to maintenance, keep the watch away from extreme temperatures and magnetic fields. Clean it regularly with a soft, dry cloth to keep it looking new. If you notice any issues with the movement or the watch stops working, it's best to take it to a professional Longines service center for repair. Also, avoid exposing the watch to water more than its specified water - resistance level to prevent damage.
