ABSTRACT:
To avoid having to pierce them, which would be detrimental to their mechanical resistance to pull, the end portions (5, 6) of the wristlet are retained in slots (3, 4) provided in the watch-case middle (1) by pins (7, 8) partly accommodated in grooves (9, 10) formed in one surface of the slots (3, 4).
