Using your M5GO watch strap is easy. First, take the watchband and use the Allen key to remove the existing strap from your M5GO watch if there is one. Then, attach the new nylon strap using the connector parts, spring pins, and screws. Make sure all parts are securely fastened. When it comes to maintenance, keep the strap clean by gently wiping it with a soft, damp cloth. Avoid exposing it to harsh chemicals or extreme temperatures. If you notice any loose parts, use the Allen key to tighten them up. That's all there is to it! Enjoy your new M5GO watch strap.
