Got this watch in Jan 2011 and have been wearing it since.. It used to be very accuarate until recently I noticed that it is running very slow.. Perhaps it was already running slow for quite sometime but i did not really test it thus missing it.. Can be up to 30 seconds slow per day.. I normally put my watch with dial facing up at night..
I did some testing and placed my watch with dial facing down to counter the inaccuracy of the movement.. It has been running for 5 1/2 days since the last time I adjusted it.. So far it did corrected the timing.. I managed to get -30 seconds after 5 1/2 days..
Does watches run faster with the dial facing down instead of dial facing up? It seems to me that both positions have minimum gravity forces on them?
