The good folks at World Watch Review give us the lowdown on the Panerai Mare Nostrum PAM300: Originally designed in mid-1940s as an officer’s deck watch, the Mare Nostrum series was put in production 50 years later sporting a two-register chronograph functionality and a tachymeter scale. Although the watch looks rugged and ready for a good piece of the action, it is not actually rugged enough to withstand any serious water pressure and is by no means a diving watch.
