Don’t expect a 37mm ultra-thin dress watch here, but rather a more sophisticated looking version of the Luminor. The ‘dress’ factor is mainly due to the thinness of the cases. These thin cases could be established because of a pair of thin movements of course. The 42mm models use the hand-wound caliber P1000 (and P1000/10 for the gold version) while the 45mm models use the automatic movement caliber P4000 (P4000/10 for the gold version).
The P4000 movement by Panerai was introduced in 2014 and they decided to use it for their 45mm versions of the Due. The P1000 movement is a hand-wound caliber that only measures 3.85mm in height. No wonder Panerai is able to keep these watches at 10.50mm thick for the 42mm and 10.7mm for the 45mm models.
