what is the "V4 added weight case and bracelet" option?

[ixobelle]

for an extra $110, what does this include? Is the default bracelet hollow or too light? I don't care about a case, but wonder if this "extra" option is worth the extra ~$100?

I believe the added weight is to reach the weight of the gen that is made of white gold, which weights more than steel
