I bought this watch and knowing seiko 5 is a good brand. But all of the sudden after 3 times first is when i got the watch, second after 1 week and last one is just last night and that was after a week as will of reseting the time and date. The Crown was not good quality it was a lost thread or i spring or i don't know i just like i coudn't lock because the short and long arm was moving while i trying to lock the crown. So try a quality brand and good item.
