On Ambit models, it's easy -- you just need a T6 Torx key for the two screws. (I got one with a cheap iPhone repair tool kit.) And be careful not to lose the two tiny nuts, as they drop out of the watch as soon as the screws are out. Just lay the watch down on its face to prevent that.Anyone had any experience with fitting a new Suunto strap to their watches? Have heard conflicting ideas about the simplicity of the process...
