OP, maybe this will solve your 'problem' (or make it worse somehow):

thanks, but... ye, erm... no thanks

What do you mean by "looking at lenses?" I don't get it, you can't see the "17-55" in the viewfinder, are you staring at the front of your lens for long periods of time? I do get what you're saying, it's like playing tetris too long and then you see the shapes in your head when you try to sleep. I just can't figure out what part of a lens would be fun to stare at long enough for this phenomenon to occur. The only one that seems reasonable is through the viewfinder, but you don't see "17-55" there. Do you happen to experiment with hallucinogens?
But to answer your question, no I've never in my life seen the name of a lens on my watch. I have seen files and folders in my head while trying to go to sleep after a long day of transferring files over and over.
Hi, no, not experimenting with hallucinogens.

Also, no staring, no longer periods, and not even looking at or through lenses. I meant, that when you check the time, say on a smartphone, in the corner of your monitor while transferring those files... you will, for example, see 8:15am and it could remind you of the Canon 8-15mm that you might rather be out with taking pictures instead of transferring files.

And, in some countries we use 24h system so 4:35pm would be 16:35... 16-35mm L, etc.
