Among others I have the genuine Garmin Titanium bracelet and the genuine Garmin Graphite Silicone band. The bracelet marches the watch's titanium trim ring and the band marches the watch's dark gray case. I find the buckles on both uncomfortable. The titanium bracelet is also bulky.
I found this silicone band on Amazon that seems perfect for casual wear. It does not irritate the underside of the wrist.
