I purchased the X lander about 6 months ago. It is a very durable watch and the
band is made of water resistant leather. Some come with the fabric
band but I've heard that the fabric
bands tend to start smelling pretty bad after a few months use. As far as the comparison between the
vector and the X lander, I won't be much help there, I only own the X lander. It has been a good watch, the only complaint that I have is that the leather
band tends to stretch after awhile. I'm planning to replace the
band with the military X lander
band which I believe is plastic when the leather
band becomes unserviceable. Also, the X Lander doesn't have dual time zone capability.
I hope this helps.
