The M9 is actually bigger than the
X6 as well as the standard
Vector watch, remember, this watch is tranmitting to satellites. I think it would be hard to make real small.
I will note, that after putting it on, it doesn't have a real big feel like the
Vector, probably because it doesn't have a big bezel on it. It's got a real smoothness about it. You can also see the comparison photo on this forum under "Suuntowatches.com"
the actual measurements are: 56mm x 56mm x 17mm
Or: 2.2" x 2.2" x .67"
hope that helps,
