摘要： A buckle having a lock mechanism for a watch with opposite bands is disclosed. The lock mechanism (40) is provided in a frame member (20) secured to one of the bands (37). The lock mechanism comprises a lock lever (41) having a locking portion and a pressing-up lever (42) having a pressing-up slant, each of the levers being laterally slidably mounted in the frame member, and a spring (43) provided so as to outwardly urge both the levers. A clasp (30) attached to the other band has a lock member corresponding to the lock lever and a pressing-up slant member (34) corresponding to the pressing-up lever. The lock lever engages with the lock member to lock the clasp. When the lock is released, the pressing-up lever pushes up the pressing-up slant member, thereby disengaging the clasp. The locking portion of the lock lever and the pressing-up slant of the pressing-up lever are disposed so as to overlap with each other. An operating lug of one of the levers is bent so that operating lugs of both the levers project from holes formed in side frames of the frame member at the same height.
