When I heard it was automatic, I was delighted as no batteries required. I have worn it now for about 6 weeks and only taken it off to shower etc.
I really like this little watch and find it very comfortable to wear, however it has been running a couple of minutes fast and I have had to correct it a couple of times.
Does anyone know how long it would keep running for, if not worn? ;))
One important thing you should know is that this watch is not battery operated - it is powered by movement. That being said, the next morning when I got up for my 10:30 meeting I noticed that the watch was at 9:00 and didn't think anything of it until 45 minutes later it was still 9:00. As I was running late to my meeting I wonder how this watch would ever function accurately unless one wears it to bed and then waves their arm around during their sleep. I'm sad it say I that I am very disappointed with this watch and hope to return it in the very near future.
