As some of my have read I just recently got a 164. Today i decide take of the black mx gator and put back on the brown oem gater. I notice that the brown oem had a tubue in the strap, where as the black oem did not come with a tube. Is it necessary to have the tube and what is the function of the tube? I appoligize if these question have been answered before.
Thanks

serves a purpose. In the past the strap has rubbed on the screw loosening it up and it may then work it's way out....which would be a catastrophe! The tube will take the rubbing and not loosen the screw. It is not essential but something to pay attention to. You should be able to slide the tubes from out of your first strap and put them in the second.
Good luck,

Safer to use the tube

I asked this question last week when I changed straps for the first time. Yes the screws will loosen after prolonged usage without the tubes. Won't want the watch to break away from the strap while wearing it... safer to use the tube. Thus if one buys 3rd party straps the lug end should be wide enough to accomodate the tube.
Of course, just because these guys had the same experience as me, as well as a few others here with thier strap screws loosening without tubes doesn't mean it will be the same experience for everyone. If I were going to error though, I would want to error on the side of caution and it makes sense to me to be safe instead of sorry.
