Having shopped at Tourneau frequently back home, I was astounded at the size of this location. While they do not carry every brand of luxury watch (a fool's errand), what they do have is a huge selection paired with excellent customer service. The two employees who helped us were both attentive and knowledgeable, and I never felt rushed to make a decision. In addition, they twice brought us cold water while we shopped. While I know this is not why people shop here, I felt it was a nice touch (plus I was just really thirsty).
One possible downside is that due to the vast selection and attractive displays, this store may pose a red level threat to your bank account. Also, the seconds salesperson helping us sold us on an extra policy to cover scratches and any other exterior problems. I typically do not like when a salesperson does this (many stores use this tactic as a way to boost their bottom line), but because of how easy it is to bang up a watch, you may feel it is a worthwhile expenditure.
