摘要:
In an electronic timepiece equipped with both an analog display section having time indicating hands and a digital display section, a time correction system is provided whereby correction of both the analog and digital time displays can be performed by rotation of a crown, with the directions of rotation of the crown for time data incrementation and decrementation being identical both for analog and digital display correction. Selection of either analog time correction or digital time correction is performed simply by pulling the crown out to either of two axial positions. Correction of both analog and digital time display information is thereby simplified and made more rapid, while the number of external operating members is reduced.
