Summary: I bought this for my husband as a Christmas gift. When he opened it he realized it didn't come with a battery. It also pulls his arm hair if it slides around at all. We will be seeing if it can be resized, but if not I guess that will be too bad for us. As for customer service, I ordered the watch on November 27 and didn't receive it until December 21. That annoyed me butI emailed Mr. Watch and they were very prompt in responding.
Summary: To start with the most important- the watch is lovely! It does exactly what it was intended to-shows You the correct time. Previously I have heard quite a lot of bad things about how inaccurate automatic watches tend to be. At least with my Seiko, this is not the case. It keeps accurate time. About the automatic mechanism- if You wear the watch for about 2 hours every day it would be enough to keep it going for the rest of the day. SO it is quite good I suppose.
