I'd guess for a few reasons...
While an IWC theme park seems like fun to IWC collectors, to me the real question is (a) how much money will it make, directly or indirectly, relative to (b) how much will it cost.
Frankly, I have doubts about the cost-benefits of the concept --although of course I'm not IWC nor do I have any inside knowledge. It has a large cost, and I'm not sure that the concept will sell enough additional watches to justify the cost. I would guess off the top of my head that the store would have to sell a lot more watches to cover its cost. Depending on the numbers, that's possible except (a) how many still would be sold with a less ambitious store and (b) what stops the customer from looking at the boutique and walking down the street to another (independent) dealer?
To me, one of the advantages of such a store may be that the benefits are public relations. This boutique might be more of a communications strategy. Likewise, I've heard that some of the watch boutiques on Madison Ave, in New York don't make any money, but are there for publicity. Their rent and staff costs are "justified" by the presence of the store. I'm not sure, if I were CEO, I'd buy that logic, but I think it might apply more so, if at all, in an area with a concentrated watch buying population --like Hong Kong.
But I think that direct experience doesn't translate as well to one city in a country like the U.S. that is quite spread out. Publicity on the streets of NY doesn't translate well to other parts of the same market, at least compared to Hong Kong.
I really like the store, at least from what I've seen on the Internet, and I hope the concept proves fruitful. But I also think it doesn't translate easily to many other markets.
But then again, perhaps that's why I'm not CEO :)
