In essence, the three new Altiplano with date models we have here are very much in line with those vintage Piagets, and come 60 years after the creation of the original 9P caliber, the first ultra-slim, manually-wound movement from Piaget (the 12P wouldn’t be patented until 1959 and wouldn’t come to market until 1960). Of course, the diameter of the new watches have increased from an original 32/34mm (depending on the model) to an uniform 40mm. One important point, the slim cases are still only made in precious metals, including 18k white, rose, and yellow gold depending on the reference. Another thing to love, each comes with a matching pin buckle, as opposed to the deployant clasp too many modern watches seem to carry. I struggle to find any option more comfortable than a simple buckle, which can also be exquisitely signed/stamped. That certainly never hurts.
The dial has also kept its original characteristics, with long indexes for the hours, including the double index at 12 o’clock. Even more astoundingly, the original font was also transposed to the modern iteration, with the cursive “Automatic” instead of the less romantic all-caps moniker that we find on most modern Piagets. The position and style of the date window is faithful to the design of the vintage models too, except that the three o’clock index got shortened in order to further improve the balance of the dial on the new watches.
