I had a Ticwatch Pro 3 and a Ticwatch E3. I'm 82 and my fitness routine involves walking my dog twice a day. On both watches the normal walk was around .9 miles. Now I have a Ticwatch 5 Pro and the walk last night and this morning were .5 miles. Is the pedometer adjustable? Is it linked to the height you've listed? Is my Ticwatch bad?
