Luminor Chrono Titanium/Steel PAM 52
Panerai's Luminor Chrono Titanium/Steel PAM 52 was the original production run for the chronographs in the Contemporary line back in 1999. There are two design traits that differentiate PAM 52 from the others and those are contrasting subdials and lack of the date indicator. Only 500 of these were ever made.
