Apple watch

Thank you so much Rudegar. This has really helped me to decide what to do with my Apple Watch. If the battery is too expensive (which it seems to be by your info) I won’t bother getting it fixed. I have the dreaded Apple on the black background also the dreaded red and at times green snake and have tried pressing the 2 side buttons, tapping the watch, putting it in the freezer for 30 mins, then I have let the watch completely rundown to zero and then re-charge - all to no avail nothing working only the Apple logo on a black screen. So thank you once again for your help it was good of you.
