Thanks everyone for your opinions. After visiting 3 stores for 5 times, and learned all about Rolex in past month, and revaluate my ultimate luxurious purchase, I finally decided to have one beautiful Rolex. It's my ultimate Christmas gift from my SO. It's a Lady-datejust 26mm with MOP dial10 diamond markers, 18k Y jubilee bracelet. I got with almost 20%off from AD in Los Angeles. I love it so much that I don't think I would buy another watch in my life. Merry Christmas.
