I prefer the one that is on it, but that's just me. I like metal bands better.
The bracelet
My bracelet is really tight. I’ve tried to use the tool to release one side of the spring at at a time. Then pull on the band while releasing the other side. Haven’t been successful yet…
When those are super tight to the case, sometimes the only proper way to remove it without bending it is to use a tool that compresses both sides of the spring bar at the same time. They can be pricey though.
I like rubber or leather straps. Never liked NATOs and bracelets are either too tight or too loose. They kinda tug on my arm hairs too.
