But unfortunately couldn't find a Jumbo to try on. I could have waited to try and find one but I really liked the way the 15400 wore on me and decided to go for it. I happened to be in the Beverly Hills AP Boutique last week and they had a Jumbo in stock. I tried it on and realized that the 15400 was the right decision for me. The Jumbo is beautiful and I understand why so many people love it, but it just felt too small/delicate on my wrist and with my 6' 4" frame.
