The world's thinnest self-winding movement is now only 2.35mm thick - the equivalent of two stacked CDs. Piaget celebrates the 50th anniversary of its famous Calibre 12P movement with the new ultra-thin Calibre 1200P, which will be equipping the Piaget Altiplano 43mm anniversary edition model.
'We are celebrating 50 years of ultra-thin history,' says Philippe L?opold-Metzger, chief executive officer of Piaget.
'With these new movements, the watches this year are sleeker, more elegant, more distinctive.'
Like the 12P, this year's version features only hour and minute functions. For those who prefer more dial adornment with the same ultra-thin look, the new Calibre 1208P, launched alongside the 1200P, is also 2.35mm thick and features a small seconds display at four o'clock.
The 1208P movement equips the new Piaget Altiplano automatic 43mm model. Piaget broke two ultra-thin records this year with these releases. In addition to the 1200P and 1208P, the two Piaget Altiplano 43mm models equipped with the movements also claim the title of the world's thinnest automatic watch at 5.25mm thick.
Even without complications, the parts in an automatic winding mechanism can still significantly add to a movement's thickness.
