Great Service is a commodity that is hard to come by. Even "good" service. I make this general statement that the consumer goods industry have not understood the concept of repeat customers. That's what I love about Japan. They are truly (for the most part) customer/client oriented. The impeccable I receive when traveling there spoiled me to the point that upon returning home, I can easily get frustrated with the Americanized service. But I am glad to hear that Patek Philippe's service has "overall" been pleasing. Especially with your 5550.
