After closly reviewing the pics it does seem to be a V5, I base this on that the V5 has the correct "maxi style" hour markers.The "Ultimate" hour markers are not as exact i.e. the metal ring portion is slightly thicker and the lume portion is slightly smaller. So it is a V5 no doubt, but it has an "Ultimate" incorrect 10 bezel. Another inconsistancy is the lume, which is terrible, even for rep standards, at the very least the V5 should have the same color lume on hands,markers & pearl. I hope that Eurotimez/Chris makes things right for you, if it were me I would ask for a totaly new replacemet & not just accept a replacement bezel.
It's a shame that the V5 is such a "hit or miss", plz keep us informed about the progress.
All the best always
