try
Genuine Suunto watch bands: rubber straps, composite watchbands, steel and titanium bracelets and look in the fine print of the descriptions. You will find x6hrt listed as one of the watches the various
bands fit. You may be able to find it for less. I am sure that a small screwdriver is all that you will need to replace the
band. The instructions given at
http://www.suuntowatches.com/assets/...ent_Manual.pdf or
http://www.suuntowatches.com/assets/...ent_Manual.pdf should suffice.
