The New Panerai Mare Nostrum Acciaio 42mm
Created back in 1943 for the Italian Navy, The Mare Nostrum was the first chronograph produced by Panerai.
In 1993, Panerai re-released the watch, and kept it in production until 1997.
The newest version of the watch is much like the 1993 re-release. This time around the watch has a few more upgrades including a 42 hour power reserve and a chronograph.
The watch retails for $10, 200 at Panarai.com
