The procedure requires removal of the pins connecting the strap to the lugs. Position the watch on a soft cushion with the lug facing upward, use a dedicated tool (spring bar tool or small hammer and punch) to extract the pin by gently pushing it from the opposite side, insert the new strap by realigning the holes, and reinsert the pin until you feel the locking click.
