The watch was ticking slightly fast from purchase however I thought it would just settle in, it has not and still gains around a minute every few days....
Also the crown to adjust the time simply comes out when I try to change the time. This also then results in the sub dial being the wrong time as it seems to catch on only sometimes to the changing of time. 
I have took this to a proffesional who said they will not touch the watch because it is simply faulty from new, this is why I now require a repair/replacement for this.
Thanks
