Well the
X6 is dark green. However it made of a meterial that has some dull refletive tones, so it is a very hard product to take a photo of and have acurate color reproduction. I took a photo of this watch to have it look dark grey when in actual sun light and seen in person it is a dark green. Seriously I dont doubt that you have a grey
x6. But I dont know where you got it as it has to be a proto-type. Call
Suunto see what they say. 1800 -543-9124
