After successfully purchasing the RB2, ROO Navy (2014), and the 15202, all within a few months, I was offered the 2015 AP Diver on the weekend. It is the latest version that has a crystal back announced in SIHH 2015. Though its a secondhand and just 8 month old, comes with a damn good price to say NO... Now, I guess I have a nice little collection, at least for the time being unless something more exciting pop up...
