We would need to talk about GEN PAMs and REP PAMs, because the reasons are different in each case
GEN PAMs
The PANERAI History and legend
There are a lot of attractive history and legends behind the PAMs and their designs
The distinctive look and limited production – Great collectability
The modern Panerai have hit the nail right on the head when it comes to creating a cult watch with great collectability.
The Panerai watches have very distinctive striking looks, they are produced in relatively small quantities, and every year there are unique editions of truly different watches, not simply a rehash of last year's model with a subtly different dial. For these limited or special editions Paneari produces fewer watches than the market demands. Retailers may only receive a few limited edition pieces each per year and there are long waiting lists for popular models.
The Lume
All Panerai watches due to their original application in military diving activities have very good “Lume”. This feature gives to the Panerai watches a very special attraction among the fans.
The Panerai Straps
Furthermore, you can change completely the look of your Panerai just changing the strap. Almost all Panerai models accept every type of strap and you can adapt the style of your watch to your taste or to all situations and environments.
There is a huge range and a lot of Strap types for Panerai watches in the market.
Panerai Watches are especially prepared for an easy change of the strap. You can literally change the watch in few minutes. See Section 6- OEM & AFTERMARKET STRAPS FOR PANERAI WATCHES
REP PAMs
Wide Range
We have a lot of types from sporty to dressy with a lot of good choices with great quality
Quality and price
There are many PAM replicas with awesome quality, almost impossible to detect and with very reasonable prices
Prices of Pam Super replicas are usually reasonable and lower than equivalent Super reps of other brands like AP or Hublot.
Information
There is a lot of good info in forums regarding PAM replicas with very detailed reviews. In this way people can select the reps and make their choices assuring that they will buy the watch they want with the quality they are looking for.
PAM rep are credible
The price of many GEN PAMs is not as high as to make the reps few credible.
Many real fans of PAM brand could buy a GEN PAM if they really want it.
It is not the same with brands like AP, Breguet, Vacheron Constantin, Patek Philippe, Hublot…
Reps of PAms are not as known as Rolex reps for example.
A rep PAM is usually not automatically taken as rep
