This replacement Garmin S2 approach golf watch strap came with a full strap and two pins and two special screwdrivers needed to remove and replace the pins and new strap. It took about ten minutes to completely remove and replace a side. Mainly because it's a bit awkward to hold the clock and drivers while removing and replacing the pins. I suggest a nice clean workspace as the parts are tiny and if you drop one you want it to be easy to find. Since Garmin no longer supports this model, this was a very easy decision.
