A multiple band sizing and repairing device is provided with a base and a plurality of blocks rising from the base for receiving and securing a watch band along its edge. The blocks are separated by varying distances from each other to form channels of varying widths therebetween to accommodate watch bands of varying thickness. A pair of shoulders extend from one side of the base and are separated from each other to form a gap therebetween. A passageway in each shoulder permits a pair of bolts to extend through the pair of shoulders. Upon rotation of the bolts, a vice is formed wherein the passageways guide movement of the bolts therethrough in applying pressure to a pin of the band. A hollow tip is provided at the inner end of at least one bolt so that the pin can be receivingly seated and held by the tip. Each block also includes a receptor for seating a bit therein. The bit serves as a screwdriver to engage and thereby prevent rotation of a screw connecting the band to a watchcase when otherwise operating on the band.
