These are not only watches at very different prices, they're also watches that express very different design philosophies. The Slim d'Hermès is in some ways the most contemporary of the three – it's all about design choices, and such technical aspects as the watch has are really there to act as supporting players to the design experience. The Parmigiani Fleurier Tonda 1950, on the other hand, is meant to showcase traditional Swiss fine watchmaking (if not the highest level of hand-finishing) and is easily the most conservative of the three. The Richard Mille, as is always the case with Richard Mille, is as interesting anthropologically as it is horologically: the very high cost, and the fact that it is instantly recognizable as a Richard Mille watch (and therefore, extremely costly) is part of the attraction to its intended audience, although there is much about the design and construction that gives it a kind of visual impact unlike that of watches from any other manufacturer (other than Richard Mille's imitators, of which there are, naturally, quite a few). It's also not contemporary in the same way the Slim d'Hermès is contemporary; there is much about its exclusivity, and its visually elaborate design, that is more traditional than you'd think at first glance.
