Officine Panerai Luminor 1950 Submersible 3 Days Automatic PAM 00305

New Submersible with the Panerai P. 9000 movement. Another new watch Panerai launched at SIHH 2009 is a new Submersible version of its Luminor watches. Internally, the Officine Panerai Luminor 1950 Submersible 3 Days Automatic PAM 00305 is identical to the new Marina PAM 00312 we took a look at a few days ago.

The movement in the PAM 312 is the new for 2009, built by Panerai P. 9000 calibre. This self winding movement has a three day power reserve and produces 28,800 vibrations per hour. The PAM 305, like the PAM 312, also has a clear-case back that allows you to look at the watch mechanism in action. The PAM 305 falls within Panerai's manifaturra line, which means that it will be somewhat more expensive than their watches with modified third party movements. The use of brushed titanium for the case will also add to the cost.

Differences. While the PAM 305 is internally similar to the PAM 312, there is plenty to distinguish the two. The PAM 305 comes in a massive 47mm 1950 case with a unidirectional rotating bezel used for measuring periods of elapsed time of up to 60 minutes making it a more contemporary divers watch. It also comes with a 4mm thick crystal (2.6mm on the PAM 305).

300 meters water resistance. Unfortunately, despite its larger girth and thicker glass, water resistance is rated at the same 300 meters as the PAM 305, which is a bit disappointing for such a massive watch. With the Omega Planet Ocean rated at 600 meters water resistance and the Rolex Sea Dweller DEEPSEA providing a rating of 3990 meters... the 300 meter rating for the PAM 305 is disapointing. I suspect this has something to do with the decision to with the clear crystal window on the PAM 305's case back.
