Abstract: A flexible band with clip-on watch module includes a band, a watch movement, a display, a surrounding case and an attachment mechanism. The attachment mechanism has several embodiments. These include a channel beneath the case comprised of two pair of opposed prongs; an elastic member passed beneath the band and the case and secured to ridges on the top surface of the case; an underband platform suspended from the case with retaining members at a side edge; a hingedly attached retaining clip that encloses the band and snaps onto a side of the case; one or more lateral slots in a side edge of the case into which the band is inserted; and a curved support platform under the watch module with retaining notches at either end for retention of a folded and flattened band. The case, recess, channel and attachment mechanism may be curved to better fit the wrist.
