Apple watch series order 3 38mm

Product Name: Apple watch series order 3 38mm
Apple Watch in great condition. It will come with a basic black band(pictured), the charger and box. THE MICROPHONE DOES NOT WORK. Everything else works perfectly fine. You can still receive calls but since the microphone does not work, the person on the other line will not hear you. Also Siri won't detect your voice. Everything else like tracking workouts, texting, heart rate etc works. I was gifted a new watch so selling this one. Might be an easy fix but I never tried anything. Please let me know if you have any questions order prior to purchasing :).
