I have recently upgraded from Spartan Ultra to the Peak Pro Titanium. I wear the watch every day and I have noticed that my steps have reduced about 20% just by changing watches. For example, today I did a 10.2 km suburban walk and only recorded 8,971 steps during the walk. I am a rogainer and I know my actual is about 1,200 steps per km. I had nothing in my watch hand. I am very happy with the Peak Pro Titanium, but I am disappointed that my step counts have been hammered by a watch change.
