Hmmm 0-6, I'm stumped!

Maybe to time an egg?

I always liked the real PCA Monaco

: So, the original has a 30 minute register and perpetual seconds.
: This has what would seem to be a 12 hour register on the right,
: fair enough, and a 0-6 register on the left... hang on, what's a
: 0-6 register?! Or maybe it's 1-7 and it Bluetooth syncs to your
: Porsche rev counter so you can look at your engine speed on your
: watch shortly before crashing into something hard and painful. I
: suspect it's one of those "chronograph" movements
: where this register actually shows day of the week and they just
: changed the graphics without thinking what sort of functionality
: a 0-6 scale would be supposed to supply! Any other suggestions
: welcome...
