Just bought my first tasty watch ever, it’s a Aqua Terra Chronograph GMT 2011 and I’m loving it.

Now should the crown be tightened so it doesn’t move because mine doesn’t seem to lock?

 

Have you tried pushing down the crown and then turning it? It should be almost flush to the case.

 

Just trying seems to be in all the way, it will turn anti clockwise but not clockwise?

 

Hmm that's interesting, maybe the threading is stuck? If you push down on the crown, rotate counter clockwise and then clockwise, what does that do?

 

Just goes round and round freely. Just don’t want to carry on too much clockwise not knowing if that’s the right way to do it?
