There is a very serious problem. it looses about 10 MINUTES per hour and so unless it is wound up every hour it is several hours late every day! I am aware that mechanical watches may loose a couple of minutes per day, but not several hours ! I will send it back to you; as it is so new i expect you to simply replace it - but please check it properly before sending it on to me.  This was a Christmas present and it is very disappointing !!
