I look at it slightly differently. Imagine, I placed an order with no deposit and specified a particular number of the limited edition with my order. In ten months time when the watch arrives, I tell the boutique I am not interested in the watch any longer. In that ten month period, there could very well have been a customer who wanted to buy the watch with my number but he did not do so because it was not available and the only numbers available were numbers he would never choose (some cultures are very superstitious with numbers). Yes I agree that a watch such as this would eventually sell but the boutique in my opinion is only right to ask for a sizeable deposit for such a purchase. I was at the Patek Salon in London yesterday and on enquiring about a minute repeater which has a lengthy two year waiting list or more, I was told that the deposit would be 30 percent. At least with the Cartier, the price is fixed but with a Patek, the price one has to pay is the delivery price and in two years time, I have little doubt that the price would not be stagnant. And by the way, I was merely enquiring as a Patek minute repeater in watch form is unlikely to be attainable in my lifetime
