The end of the 1990s saw a tremendous resurgence of interest in mechanical watchmaking. Customer demand is once again directed towards exceptional complications, such as the perpetual calendar and minute repeater. But the focus of attention and interest is now on watches featuring a tourbillon regulator. Let us recall that the tourbillon is not, properly speaking, a complication, but a device for counteracting the effects of gravity. We can understand the interest. Indeed, what watchmaking enthusiast hasn't dreamt of being able to observe the tourbillon's rotation in its cage? In a word, it is magical!
In 1996, Blancpain defined a new standard with its calibre 25, the first movement with tourbillon regulator featuring self-winding with 8 days' power reserve.
