In my opinion, Panerai is wise not to make more Bronzos merely because there was excess demand for the 382. The decision not to create a new bronze piece creates demand for limited editions generally, as people understand they cannot count on a later, "consolation" edition.
Since Eve and the apple, it's been a tried and true marketing strategy to tell someone she cannot have something and she wants it even more. Therefore, the Bronzo "lesson" is "better line up and buy the special editions you want because there won't be any more of them." The trick of course is to keep making things people want to buy, and in limited quantities.
Merely because the Bronzo sold out and is in high demand by itself probably is not a reason to make more. It would just commoditize it, which is contrary to the exclusivity strategy I think they are pursuing. Along the same lines, I think the boutique model is less about keeping profits in house and more about exclusivity. Although selling through boutiques means they don't have to sell "wholesale" to ADs, Panerai instead has to invest in stores, employees, overhead etc., which most definitely cuts into profits. I think the fewer places there are to buy Pams, the more exclusive they seem. Panerai also gets to control the sales experience, which means ensuring sales persons have adequate product knowledge, commitment to the brand, customer service, etc.
Anyway, just my opinion. I know nothing about the inner workings of Richemont or Panerai. As much as I would have liked a Bronzo, I appreciate Panerai's decision to limit them. I hope they resist the temptation to make as many watches as the market wants to buy.
