the 47mm is what makes the 372. im not sure if i wouldve pulled the trigger had it been a 44mm. and although i have 6.5" wrists which is considered small in many's opinions, the watch just puts a big fat smile on my face when it gets strapped on. in the end, you make it work or get used to the size of it. i wouldn't have bought it to begin with otherwise. im also 6'1" btw so that helps with the small wrists. as for all the 372's in the CM, a big factor may be because another 2500 is being released and flippers are dumping them.
there's a few other threads that touches on the 372 size vs 44's in case you missed it....
