How to hard reset an Apple Watch?

Got a "too many password attempts" message and so need to do a hard reset but no matter what it isn't working. I have been all over Google and Apple Support and there appear to be three approaches, all listed below. None of them have worked, even method #3 which seems to have been a successful method of last resort when #1 and #2 failed.

Method #1

1. Connect your watch to its charging cable, with power connected.
2. Press and hold the side button until you see the Power Off slider.
3. Press firmly on Power Off (do not try to slide it - just press down more firmly than a normal tap) and then tap on Erase all content and settings.

Method #2

1. Put your watch on its charger and keep it there until you complete these steps.
2. Press and hold the side button until you see Power Off.
3. Press and hold the Digital Crown until you see Erase all content and settings.

Method #3

1. Press and hold both the side button and Digital Crown for 10 seconds, then release both buttons when you see the Apple logo.
2. Wait a few seconds, then hold down just the side button for about 20 seconds or until the "erase all settings" prompt shows up.
3. Click the prompt, then click the green check button.

Some additional info:

• Its a Series 2 watch running watchOS 6.3
• The phone the watch is paired to was present at all times, even thought that shouldn't matter.
• Yes, I have done everything with the fully charged watch attached to the charging cable.

No matter what, the "erase all settings" prompt never appears. I seem to have run out of options. Any ideas?
