hi guys, sorry noob to panerai. but what is the difference between all these similar looking panerai's? 0005, 0183, 0111, 0176, 0048, 0177, etc... is it the year they are made or based on differences of the movements? is it the dial and how the lum is applied? to my untrained eye they look like i can close my eyes and just pick one... sorry if it's been answered before.
