Maybe I'm crazy, but has this happened to you? Online, looking at photos of watches, I start to see them move. My first glance at the seconds hand and for a split second I see it ticking away. I will, of course, do a double take and then it stops. But for the shortest amount of time I believe it's moving.
Funny thing is, when I first started seeing this all the movement was in second ticks. Now, maybe because all I buy is automatic now, the movement is in the sweeping motion.
I hope this is not a sign that my hobby has gotten out of hand.
