Hoping someone familiar with the Aquis can comment on this. I have a question regarding the winding/tightening of the Aquis crown. I bought my brother the watch in question 3 years ago and he's noticed that when he winds the crown to lock it in, i.e. when pushing down and catching it so it no longer freely winds but tightens, it only tightens about a 1/3 turn or so. He swears it used to wind in a couple full turns before it was locked down. When I hold the watch up to the light I can see a tiny bit of space between the crown's bottom and the side of the case. How much should a healthy crown turn in order to properly lock it down? This can be different on different watch brands so I'm not familiar with how the Oris should behave. Thanks.
