[Other SmartWatches] Lokifish Marz:
Pulled the v1.5 update.zip and digging through it. SmartQ is not a "Big name" in the U.S. but I have had good experience with them in the past with their v5 and v7. Contrary to some sources it is showing as 4.1/API-16 in the build.prop. I also noticed that a zRAM script is in the firmware as well. For those not familiar with IPX7 rating it's pretty much the same as IP67.

For 99USD this is a pretty sweet deal. Here's a French review which shows what appears to be gesture wake as well as proximity detection.
