Piaget introduced the world’s thinnest Minute Repeater at SIHH this past January. They also added to their Altiplano line with the world’s thinnest automatic watch and movement with a date. Not only did they add a date, but they also reduced the case diameter from 43 mm to 40 mm for this particular model. In comparison to the larger 43 mm Altiplanos, the 40 mm model seems just right on my wrist (see below).

Powered by the famously thin 12P based movement, which is entirely developed in-house by Piaget, and measuring only 3 mm thick, it is indeed the thinnest automatic with a date in the world. The new caliber 1205P has a 44-hour power reserve, a frequency of 21,600 (3Hz) and 221 parts (27 which are jewels). It is finish with circular Côtes de Genève, circular-grained mainplate, beveled bridges, sunray-brushed wheels, blued screws, dedicated index-assembly and a rose gold micro-rotor engraved with the Piaget coat of arms.

The new 40 mm diameter case is mere 6.36 mm thick (again the world’s thinnest automatic watch with date) and comes in 18K white gold, 18K rose gold or 18K rose gold with a bezel set with 72 diamonds. Sapphire crystal case back allows a view into the highly finished movement. Black alligator leather strap with 18K white gold pin buckle or brown alligator leather strap with 18K rose gold pin buckle.
