Hi, I also have a Grand turismo XL - limited edition with the white/silver dial.
The second hand on my watch move with an occational small skip. I do not know if this is normal and because of the long second hand I am seeing things, or the movement needs a slight adjustment. I know that the movement is a larger ETA design. When wearing the watch I can move my wrist up and down and actually hear the watch winding, real cool effect!
This watch is real nice, it's big, light on the wrist with the rubber strap, and has a dial that is very easy to read. The long second hand with the red arrow sweeps around the edge of the dial, real real nice! Thanks, B.
