U measuring at the same power reserve level ? Sometime the amount of power remaining in spring can yield diff measurement . Full vs near deplete
i measure using hairspring app

should be quite accurate since it use sound frequency, tested 3 days consecutively had been in the 2 sec range
it happened after i put my watch in my sling bag on my right side when i was wearing a milanese loop with magnetic attachment for my fitbit charge 2 on my right hand


ps: could be power reserve too, watch stopped after 1day + of no wear, i shake it abit to start it and start measuring
