Being the watch nut that I am I find I stare many times at people wrists trying to see what watch they wear.
I commute to work and back via bus and subway so I get to see many people everyday.
In most cases if people wear watches I dont recongine they watches, these in most cases are cheap quartz watchs but in some cases I do recognise.
The watch I see the most and recognise is Omega Seamaster.
Second most common is the Rolex Submariner.
