In order to commemorate the 20th anniversary of SIHH (Salon International de la Haute Horlogerie), Panerai has decided to reissue it’s classic Mare Nostrum watch. It is not available yet as they are waiting for the official 2010 SIHH event. The watch is purported to sell for around $36,000. The Mare Nostrum features a monstrous 52mm dial and is reported as being based on a hand-wound Minerva chronograph movement, dubbed the Panerai OP XXV caliber. In short, this watch is a looker and is sure to capture the attention of any onlookers.
