A structure comprising a watch case; a pair of lugs each extending from one of the sides of the watch case and being provided with a threaded hole; a band; a pair of cone point screws; a connector secured to the underside of an end portion of the band, the connector being bent into a U-shape to define a base wall and a pair of side walls, the side walls being provided with a pair of attachment openings, the band being closely attached to the watch case by placing the end portion of the band on the top surfaces of the lugs and tightening the cone point screws respectively into the threaded holes of the side lugs so that the cone points engage with the pair of attachment openings provided in the connector; and a bend preventing member comprising a bending wall extending from the base wall of the connector. The bending wall is bent so as to cause a fold in the direction of the width of the band and inserted between the pair of walls so that the bending wall can support the pair of walls of the connector from the inside so as to keep a fixed space betwen the side walls against forces exerted by the cone point screws towards the inside.

Watch case and band attachment structure

A structure comprising a watch case; a pair of lugs each extending from the watch case and having an upper surface in a lower position than the upper surface of the watch case; a band; and a connector secured to the underside of the end portion of the band, the band being closely attached to the watch case by placing the end of the band on the upper surfaces of the lugs and tightening cone point screws into threaded holes provided near distal ends of the sides of the lugs so that the cone points of the screws hold firmly a pair of attachment openings provided in said connector against the watch case.
