normally i would agree with this, but not in this case, i think motion would have more to do with watch speeding up at this point, temperature and gravity usually accounts to about +-5sec deviation together but +25 above the tolerances listed will not be be due to temperature unless he is running in 90 degree weather for a full hour but not from normal activity in 60 degree weather
This is amazing, upon closer inspection / disassembled the back. The watch advertisement says 6R15 internal movement. The movement is stamped 4R35B and it does not hack as a 4R35B. I guess it was a cheap knock-off. There ya go, be careful of liquidation sales.
