That's great to hear! I usually only hear complaints when something is going wrong. Over a month is what I routinely see here too with the watches I have kicking around.
When there is movement the accelerometer does enter a higher power mode and that can affect battery, but it's not massive. The backlight is a massive power draw if 'wake on twist' is enabled too.
