I don't religiously check these things but I'd say > +10s a day. Miles ahead of my Willard. That went ok (about the same actually) for a couple of years and then suddenly without warning started losing time. Now when I checked it after a few days it was minutes off so that will be going in for a warranty service/regulation shortly.What are you getting on +/- a day?
I think the Citizen also looks much better on a canvas / mil strap:
