About accuracy
The accuracy of mechanical watches in this instruction manual is static accuracy at
normal temperatures (between +5˚C and +35˚C).
The accuracy on the specifications may not be kept depending on the following
conditions of use:
• times the mainspring is wound
• position
• usage environment (temperature, magnetism, impact, etc.)
Times the mainspring is wound
Full winding of the mainspring ensures the most stable and accurate movement of
mechanical watches.
Position
When you wear the watch on the wrist, the position of the watch changes frequently,
and the movement of the watch is influenced by changes in the direction of gravity. This
affects accuracy of mechanical watches.
