I've been very lucky with my 300m. Timegrapher on qc pics said +0secs/day. First day or two it ran +2 secs/day and has now settled into +0 secs a day. Stoked!
But I don't mind my other watches running at around +7 sec/day and also wouldn't be concerned about +15...to me a watch really doesn't HAVE to be changed until it's 5 minutes out, which is still a few weeks before needing adjustment at 15secs/day.
