Using your Ellis & Co Stella watch is super easy. Just put on the black band and adjust it to fit your wrist comfortably. To set the time, find the small button on the side of the watch and follow the simple steps in the instruction manual. When it comes to maintenance, keep it away from water as much as possible, especially if it's not waterproof. Wipe it gently with a soft cloth to keep it clean. Avoid dropping it or exposing it to strong impacts. If you have any issues, it's best to take it to a professional watch repairer.
