I bought a nice Time Tank off the Bay but when I received it today (20th) I noticed the date was the 15th and the 5 was partially in the window. So I go to reset it, winder was well screwed in but I was careful as this is not my first Oakley watch. The date moved forward but not with the precision of a Cartier but nonetheless it wound forward, I carried on and of course forgot to set it to yesterday so had to keep going, got to the 28th and it stopped, 8 partially in the window and that was that. I Can feel it clicking in the winder with each rotation but no date move. Everything else is good, time, Crono reset etc. No problem with seller who is trustworthy - get refund or money off for repair. So my question, in order to help with the decision, is where does the fault lie- is it in the body of the watch in which case would probably be cheaper to swap the mech out, or is it in the winder spindle (sheared) in which case different kettle of fish as they don't grow on trees, keeping in mind I am in the UK. Any help would be appreciated.
