Patent number: 11372372Abstract: In a plan view in an axial direction of an indicating hand axle of a small second hand, three arrangement relationships described below are satisfied between a 10 o'clock side information display unit and an hour hand. According to a first arrangement relationship, respective numbers of a scale are disposed line-symmetrically with respect to a virtual straight line connecting a scale and the indicating hand axle to each other. According to a second arrangement relationship, the indicating hand axle is located at a position which does not overlap an indicating hand axle of the hour hand. According to a third arrangement relationship, a portion of a rotatable range of the hour hand overlaps a rotatable range of the small second hand, and does not overlap the scale.Type: GrantFiled: February 27, 2019Date of Patent: June 28, 2022Assignee: SEIKO EPSON CORPORATIONInventors: Nobuhiko Nakanishi, Tadasuke Kotaki

Publication number: 20170003659Abstract: An electronic timepiece has a display device that displays display information, a drive mechanism that drives the display device, a crown that can perform a rotary operation, and a control device that corrects the display information displayed on the display device by the rotary operation of the crown. The control device has a single correction mode and a continuous correction mode which are selected by the rotary operation of the crown. In the single correction mode, a single correction signal is output to the drive mechanism so that the display device is corrected as much as a single correction quantity. In the continuous correction mode, a continuous correction signal is output to the drive mechanism so that the display device is corrected as much as a continuous correction quantity. The continuous correction quantity is set depending on types of the display information to be corrected in the continuous correction mode.Type: ApplicationFiled: September 16, 2016Publication date: January 5, 2017Inventor: Nobuhiko Nakanishi
