Here's an update about my Pebble watch.
I did eventually receive a reply requesting photos for the RMA. I submitted them and a short time later received an email advising me that the replacement had shipped.
This surprised me because the RMA email advised me that I would receive an email with a shipping label to send the old one back. I never received such a label.
It wasn't long before the tracking advised me that it had been shipped overseas. It sat at customs for a couple of weeks and this week it arrived in my city and at my house at the same day.
I'm pretty happy that I didn't have to spend anything to send the old one back. I wonder if that was because it's a "Kickstarter Edition"? Maybe they thought I'd like to keep it as a souvenir? I don't know.
Regardless, I now have a functional watch and I hope it lasts longer. :)
