Chosen Solution
I did a screen replacement in the AW Series 1 and it got stuck on the Apple Logo. It will stay on the Apple Logo for about 30 seconds - 1 minute. In between that time I can feel the watchs Haptic Engine go one time then the Apple Logo goes away. One click of the power button the Apple Logo returns (dont need to hold the power button just one click literally) and it repeats.
I already found the fix. So I hard reset the Apple Watch. I held down the scroll wheel & the power button for ~15 seconds. It stayed on the Apple Logo for 30 seconds - 1 minute like I stated above. ONCE the Apple logo disappeared, I clicked the Power Button and the Apple Logo came on and I immediatly held down the scroll wheel ONLY for about 10 seconds. It then booted normally. I tried this method after I took off the replacement screen and put the broken original screen back on. The original broken screen gave me the same exact issues as the replacement. Thats the exact steps I used on getting my Apple Watch Series 1 to stop freezing on the Apple Logo.
