French for "barrel," a tonneau shaped watch can be considered any watch thats somewhat in-between a curvy rectangle. Having the watch be a bit more of an odd shape, it was initially made to fit the wrist better. Being a sophisticated and elegant design, most tonneau shaped watches are quite luxurious. Some of the better known tonneau shaped watches come from the brands of Hublot and Richard Mille, amongst many other greats.
