Abstract: An improved security buckle for a wrist watch metal bracelet is disclosed which utilizes a first and second frame work, one mounted within the other, which are provided with a limited amount of relative sliding movement. A spur of the first frame work is in engagement with or is disengaged from a first traverse element of the second frame work when the two frame works are respectively in a first and second relative position. An inflexible removable traverse element is attached to the first frame work and to a first portion of the metal bracelet. A locking band attached to a second portion of the metal bracelet passes under the first traverse and is engageable with the spur when the frame works are in the second relative position and further passes through a space defined by the inflexible removable traverse element and a second traverse element on the first frame work when the frame works are in the first relative position.
