Panerai Submersible Pam24 F series,2003 production. Model OP6561 number 0636/1500(636 out of production of 1500 pieces) This was the last year of tritium T SWISS MADE T dials and as such they had this text at the very bottom. The dial is satin black with running seconds sub dial at 9 o’clock. Sapphire crystal. This watch was serviced in October 2012. This is a $400 value !!! Your will receive this fine watch with the original box and papers. Also you will receive the Panerai book as pictured and additional bands and the double Panerai deployant as pictured. Screw driver too 🙂 The retail price on this model is over $7500 and I do not believe you get all the extras you receive here. There is a tiny scratch on the crystal.
