After being subject to Machs influence for a good while I thought I'd try double twisted for a change. A strange experience 
Firstly my right wrist is bigger than my left requiring some adjustment, then I found I kept knocking one or the other, especially the right. Add to that the fact that once I have a watch on the right I tend to ignore the left 
I won't go into trying to get the watch on the right.
Give it a go and see what oddities you experience.
Cheers
