Welcome. Here's the thing with the APROO....originally, they came with seconds at 9 because of the 7750 movement. Some models had the original type dial and some modified the dial to reflect the seconds at 9. The best available is the MBW/MBK versions. These have the slow beat 7750 (21.6K). Read a bit and you'll get a perspective on the MBW watches. I have one of these and had Ziggy drop in a Swiss 7750.

Now the original APROO has seconds at 12 and many members waited till that version came out (it's now out). However to get the seconds in the right place it was necessary to add a module with additional gears to move the second hand. More gears equals more pressure on the movement. There are plenty of threads out there on the reliability of the seconds at 12....both pro and con.

So, if you're just going to try the watch out in anticipation of possibly purchasing a gen...then it doesn't really matter...buy the cheapest. If you think you might keep the watch and the 9 versus 12 issue doesn't bother you, then the MBW/MBK is the way to go.....

BTW, this is a big, heavy watch and trying it out is a smart way to go.
