MichaelC, thanks a lot for the inputs. So sad, I was really hoping to be able to change to a transparent back.

Hi, I am also looking for a new 15300, where did you get your? Thanks!

Hi guys, Since most of the RO Chrono don't have a transparent back, I am wondering if it's possible to change the solid case back to a transparent crystal one. Thanks!

Hi Gazoz, I tried the AP 15400 at the local AD and find it's too big even for my big wrists. I am wondering where you are getting a new (I assumed) AP RO 15300? I am also looking to get one. Thanks!

Hi all, I have been wanting to get an AP RO 15300/15400 for weeks, after deciding to forego the Rolex Daytona for the AP. My local AD just got the 15400 in stock and I went to try out the 15400 but found its size too big for me. Can I know where can I get a new AP 15300 (black/white) in South East A
