went back/forth with 15400 for a long time. but once i had both side-by-side at the boutique, the decision became immediate. after which i very shortly found one for a great deal.
originally thought i had to/should get rid of the ROO. IMO, had i decided on the 15400, the ROO would've been more redundant just cuz the size is so similar.
but with the jumbo, the two are far apart within the RO family to rationalize keeping both and having different 'uses'. had i gone with 15400, i do believe the ROO would have gone unworn or neglected.
some comparison shots leading up to the final acquisition.
that said, IMO, the 15400 dial is far more spectacular than the jumbo. it's simply 'alive' the way it glistens in the light. whereas the jumbo is much 'calmer' and muted.
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.
How big is your wrist BTW? The 15400 looks to wear quite large on you in that comparison shot.
