Characteristics of Mechanical watches
About time accuracy of mechanical watches
The time accuracy described on this instruction manual is the static accuracy at
normal temperature (+5˚C (+41˚F) to +35˚C (+95˚F)). The accuracy of mechanical
watches may get out of the described range depending on the following three usage
conditions or other reasons.
• Winding amount of the mainspring
• Attitude
• Usage environment (temperature, magnetism, impact, etc.)
Winding amount of the mainspring
Mechanical watches keep accuracy most stably when the mainspring is sufficiently
wound.
Attitude
Accuracy of mechanical watches varies affected by gravity. The accuracy varies
as the result that may take various attitude while worn and gravitate to a different
direction every moment.
