My watch is losing time every month.Its far greater than10-15 seconds per month.My watch isn't easy to read at night.It is great in day light but the time isn't accurate.
I brought this watch about six or eight years ago while on a cruise and love it. My only issue is the time no longer adjusts to my location - traveling to California from Pennsylvania stayed on NYC timezone instead of automatically adjusting to Chicago then Denver then LA after a few years.
