When changing the date manually if is unable to go any further than 1 or 15. If the watch said the date was the 10th and I wanted to change it to the 20th I would need to change it to 15, wait a day until it goes to 16 automatically, then change up to 20. This cannot be the expected behaviour?
 
Also the watch stops and needs rewinding every couple of days, this is despite me wearing it during the day nearly all the time.
