A battery cover structure comprising an elastic sealing member having a larg e- diameter portion and a small-diameter portion, the large-diameter portion forming a peripheral flange portion around the small-diameter portion; and a rigid member joined to the elastic sealing member and located on a side of the small-diameter portion remote fr om the large- diameter portion, the battery cover adapted for attachment to a battery acce ss hole in a watch case by inserting the elastic sealing member in the hole and engaging the peripheral flange portion with the case. Because of the rigidity imparted by the rigid member, the battery cover structure is substantially free from the risk of pushing the battery cover into the watch case to impede or damage the movement of the watch, or deforming t he battery cover itself by excessive force to cause the battery cover to come off the battery case. Furthermore, the cover has an improved appearance. Also, the battery cover structure has a reduced risk of being easily detached and accidentally swallowed by a little child or the like, or to be removed unintentionally and lost by mishandling.
