What a stunning watch. My first impression was, awesome! A very wearable watch. The strap is pliable and soft and sit very comfortable on your wrist. You do not feel the watch at all. My sixth watch from replicafactory. I have a issue with one watch but I am sure we will be able to resolve this soon.
