On forums and blogs alike, the Orient AA02 is an absolute classic and can be attributed to being the watch that started it all for collectors and enthusiasts (and Watch Idiot Savants for that matter) around the globe. The new AA02 builds upon the diver legacy. It has transitioned away from the reliable 46943 automatic movement to the more robust Caliber F6922 that is automatic, hand-winding and hacking. This new mechanical movement has removed the need for a second crown at the two o'clock position. The diving bezel has also been upgraded to be 120 click for improved precision. These changes have definitely improved the utility of the diver watch, all the while preserving the classic aesthetic that the classic diver had become known for. Appropriate for skin diving only!
