Yes it fits loose mainly to easily get the loop over my hand. The bungee is a nice idea. I think I'll do that ... more fashionable. I just need to think of a nice way to fasten it tight ... my knots kept undoing
I don't seem to have an 'extender'. I do have some long straps that came with the watch. I have a small collection now.
Here's a pic of what I meant by the 3rd buckle [hole] (red arrow) and my collection
All 5 of the straps on the right side of your picture are extenders.
If a light didn’t just come on making it obvious how to use one of them, let me know and I’ll post a picture.
