The Foretrex is a wrist-mounted navigator rather than a watch, and it straps on with hook-and-loop so it can go over a sleeve, a glove cuff or a jacket. This is the genuine Garmin replacement strap for the Foretrex 801 and the Foretrex 901 Ballistic Edition.
Hook-and-loop is the part of that setup that wears out – it collects grit and stops holding long before the unit does. Replacing the strap is cheaper and faster than working around one that has gone slack.
