TNT Royal Retro Power Reserve

Like an exciting relay race, each of the four seconds hands runs a 10-second lap before passing on the baton. But after the first two have completed their legs, the baton mysteriously disappears behind the power reserve indicator, only to reappear for the final two. Whimsical and mischievous, this complex mechanism is a world first. ---------- Automatic movement, exclusive Dubois Dépraz calibre. Hours, minutes, retrograde seconds, power-reserve indicator, date.
