Thanks. Don't know where to get it. I don't think its too expensive though, probably around $100 range, but I like it a lot. But I still can't figure out the markingson the edge, can't be depth cuz there are no gauge to indicate how deep you are. Also, this is suppose to be a F1 driver's watch or sumthn so I don't think how deep you are comes into play
Only thing I can think of is that its marking where you should shift
. The first red marking (with one stripe) is at slightly over 30 (31mph, shift into 2nd?), then 2nd marking with 2 stripes is at around 65, 3rd one with 3 stripes at 110... I don't know.
