Help needed with Nato straps ...

[jrbar-on]

Yes, I'm going over to the 'Darkside' and I'm thinking about putting a Nato strap like the one shown belo on my watch.
However, I admit it, I'm an idiot and for some reason it just isn't obvious to me as to how to put the strap
on my watch. Consequnetly I thought that I would ask the experts for advice.

Could someone please explain (via photos would be the best) how to use a three ring Nato strap like the one shown below.

Thanks a lot,

Jonathan.
