I'm not sure if it is just me but I sense a bit of Panerai fatigue. Every product eventually cools off after a while and I think that Panerai has had its run. I think they have facilitated the fatigue by a series of missteps that have been debated on this forum, which may include re-issuing and recycling watches that were rare at one point, straying too far from the roots of the brand, the poor quality movement in the Brooklyn bridge model, creating "special editions" for every possible market, and generally operating with a sense of invinceability. I get the sense that they are trying to squeeze maximum profit out of the brand at the cost of upsetting its core customers.
In previous years, I think the 399 would have set off a storm of interest. Aside from the fact that it isn't a very good replica (compare it to the JLC Polaris or Deep Sea tributes), I think people fear that they may release as many oddball variations and derivatives of the 399 that the market will bear.
