The hunt is a big part of Panerai collecting. The long path to falling in love with a piece makes it such that it is hard to fall out of love. Unfortunately I came late to the game so the older pieces are out of reach.
Some numbers no particular order and grouped by theme -
Icons 217 / 127
Base Rads J183 / 210
Historic appeal 232 / 249
Base Luminor 000 / 176
8 Days Before and after 190/ 233
Chrono Complication 246/187
Ying Yang 49/50
One other which escapes maybe Nicolas remebers.
However, these days I am struggling a little with the newer choices.
