Installed easily, though I did need to remove additional links to compensate for it being longer than the original clasp. Does the job well, the increments of lengthening are excellent and gives a good set of “steps” to a changing wrist size throughout a hot day. You can intrusive without even taking the watch off the wrist. To reduce size, it’s easier to unclasp, adjust and re-close the clasp. The only minor critique I would offer is that the ends are a little sharp - not that it fits in anywhere on your skin - but a little additional finishing here would be excellent
