I've seen the white one and I think it looks like a lollipop. It works better on a Tank as the case and strap has a slim profile. My Tank had 19mm lugs but I think even the small ones are around 15mm. I've just bid on a pretty Marmite watch right now so my taste maybe questionable
Think you have to see one of these in person if you've not already. The strap works in the same way a narrow strap on a Tank works.
