Thank you for the kind words. As for the other half, here's a few pointers to go by:
1. Always ask her opinion about a watch before you buy it. (We like to know that you care about what we think.) And don't ask, "Do you think I should get this watch?" Instead, ask "Do you like the way this watch looks, the colors, design etc...?"
2. Always try to match a purchase of your own with a purchase for her. (This will help with "understanding the spend".)
3. Don't bore her with the technical details. (That is the easiest way to lose her interest.)
"It has a 30 day power reserve!" --No
"Nadal wore the watch when he won the US Open! It was made especially for him." - Yes
