This it sort of like dream totems from Inception. You know where they had an actual object to do a reality check and what not.

How do watches fare with reality checking? First of all I kinda want a watch, and secondly I want it to be useful as a reality check, by looking at the time and either seeing it change as it shouldn't or be an completely random time.

What kind of watch should I get? Should I even get a watch? The only reason I wanted a watch besides.... having a watch is for the reality checks. If it won't work or help my reality checking then I probably won't buy.

TL;DR I want to know if watches actually help with reality checking and what kinds are the best suited?
