PLEASE READ FULL DESCRIPTION - USED: The clock winds and will keep time, you can adjust the time and the alarm time, the alarm does sound and work when set. The function S-F not sure what that does and the switch is not sticking up above the back like the alarm switch does, but you can see it not sure if it supposed to be that way or not, but does look like it could be adjusted if you use something that will fit in the slot (see second to last pic). Otherwise this clock is in really good shape and very unique.
