the 2nd and last one looks stunning! but @ 50k yen, got to lessen other purchases..
looks like I'm correcting myself.
The Japan version GW-9400J <--note the "J" tacked on to 9400 has the same inner module as will be used worldwide, that is Module 3410. It is only locked in metric units if you have TYO selected as your Home City Code/TimeZone.
The key difference between the JDM version and the export versions appears to be in the strap only. The JDM version has a fancier Carbon-fiber strap whereas the USA and EU versions will have the customary resin strap.
