Remarks:

  • Automatic for seconds, quartz for hour and minute display
  • The winding stem is used to set the quartz movement and has no connection to the mechanical movement (-> no manual winding possible)
  • The entire mechanical movement, including the automatic, is only used to move the second hand
  • To change the battery of the quartz movement, the entire plate must be removed
  • PTS is a movement supplier from Hong Kong that has movements designed in-house by various Chinese manufacturers, but also sells their standard movements. The actual manufacturer of this movement is unknown, but it is probably produced exclusively for PTS
