Alsta Teardrop Clock Pendant

I picked this little contraption up recently, and it's adorably steampunk. It's got a faceted clear glass back, and when you wind it, you can see all the gears and mechanisms inside move and tick. I've been looking online, and can't seem to find any info on it (but then again, I'm new to the whole researching old stuff online).... the lack of info makes me wonder if I just picked up a cheap trinket, or if I've got something really cool.
