    Mechanical Watches Accuracy of mechanical watches The degree to which a watch will be ahead or behind the time in one day is called a daily rate. The accuracy of mechanical watches is shown based on its average daily rate. The daily rate shown in this manual is an average value (static accuracy) measured over a number of days under constant conditions, such as spring winding, watch posture (horizontal: dial facing up, vertical: 3 hours down/6 hours up etc), temperature etc.
  • Page 26 Mechanical Watches The accuracy of mechanical watch changes with the following conditions: (1) Spring winding (2) Posture (3) Use environment (temperature/magnetic fields/shock etc) (1) Spring winding Full winding of the spring provides the most stable energy for mechanical watches, and ensures continued stable use.
  • Page 27 Mechanical Watches (3) Use environment (temperature/magnetic fields/shock etc) • Because mechanical watches use metal parts to control their accuracy, changes in temperature may cause the metal to expand or contract, which may affect the accuracy of the watch. • Because mechanical watches use metal parts, exposure to magnetic fields will affect their accuracy.
  • Page 28 Mechanical Watches If the watch becomes inaccurate Mechanical watches may become inaccurate due to wear or insufficient lubrication. Have the watch disassembled and cleaned (overhaul) every 2-3 years. Wear from long-term use may cause performance degradation, and it may be difficult to return the watch to its initial performance even after repairs.
