hi i have an officine panerai firenze 1860. i bought it from an auction but cant find the model on the net to find its true worth. the front of the watch reads 'luminor panerai, automatic, swiss made. the back reads 'officine panerai firenze 1860, divers professional, op6541, bb000000, c000/500, stainless steel, 1000m' the strap is rubber and says officine panerai and is very heavy and looks quality. can someone please help me out and identify whether this is a fake or original.
many thanks for your help
