Abstract (en)
The mechanical timer has a barrel(82) in contact with the timing wheel(20). This timing wheel(20) is mounted so as to rotate inside the mechanical timer on a single pivot(62) supporting the wheel(20) by its base(32). The wheel(20) is suspended from the underside on the single pivot(62) being entirely free on the upper side. The timing wheel(20) is made visible through the watch face. The wheel(20) makes one complete rotation in a minute and includes a second hand(90) which forms an adjustment means for the watch. ADVANTAGES/ <IMAGE>
