I have used it to remove a link from a watch band that was too large. Worked perfectly using the the block to stabilize band, the pin and the hammer. Easier to use than I anticipated. I haven't used any other components as of yet. Unfortunately one of the small screwdrivers handle came rusted. It should not affect its use though, as blade is fine. Otherwise, everything is good. Considering the low price, I can't complain. It will come in handy for future watch repairs.
