I ordered that same band along with the
Obsidian/Black on the same day I ordered the S3 white ceramic. The obsidian band arrived last Friday and I love it. The platinum band is supposed to arrive this Friday.
The watch was
supposed to arrive today by 10:30AM, but hit a customs clearance delay in Memphis, TN. No idea why, but I suspect that all imports are randomly subject to more detailed inspection. It has been in Memphis since Saturday morning. According to FedEx, it was released from customs around 12:30PM EST today, but FedEx hasn't updated the ETA.

Hopefully it will arrive tomorrow, but I'm guessing it won't arrive until Friday. I'm only one state away. Frustrating...
