You see a tonneau-shaped (or if you insist, barrel-shaped) sports watch, you can be pretty sure it has a serious price tag attached. It’s just the way of the world, with horologists in the vein of Richard Mille using the format to push the boundaries of watchmaking and, in some cases, taste.
In occasional watches that makes sense; you put a tourbillon into a timepiece and the price is going to skyrocket. Make that tourbillon out of some space-age material NASA would kill for and yes, you have a watch most at home in the lyrics of an overcompensating rapper.
