Bought to replace an aging strap on a Swiss Army watch that broke and was too big (couldn't add extra holes). There are no installation instructions, but a quick web search for "replace swiss army bracelet" gave me a link to an eHow procedure. It took me a while to remove the spring bar from the watch (with a very small screwdriver) but eventually it came off. I set the watch up on Revain like the picture here and replaced the spring bars (this keeps the straps in place, little metal rods) and I was able to attach the watch. My only comment is that the wrist loop is quite large - there are no tight cuffs for this watch, but it's a watch that can be confusing, so that shouldn't be a problem for me.
