During the setting process, one displays the value of each of the parameters to be set successively by one of the hands and of the corresponding graduation.Type: GrantFiled: February 3, 1992Date of Patent: August 24, 1993Assignee: Complications SAInventor: John Corlet

Patent number: 5083300Abstract: An improved setting mechanism for a timepiece of a known type having a frame, a gear train, a detented setting stem rotatably mounted and axially slidable in the frame and having a toothed setting pinion which is engageable and disengageable with a plurality of crown teeth arranged on one of the gear train members, the stem setting pinion being arranged on a first axis and the crown tooth gear being arranged on a second axis. The improvement comprises offsetting the first axis so that it does not intersect the second axis and skewing the crown teeth in the direction of offset so that the setting pinion engages the crown teeth from a non-radial direction to facilitate engagement on only one side of the pinion. The offset further facilitates a stem extension in a non-interfering position.Type: GrantFiled: July 10, 1991Date of Patent: January 21, 1992Assignee: Timex CorporationInventor: Herbert Schwartz

Patent number: 4995020Abstract: An electronic watch includes a "traveler's time" function which can be activated when a wearer leaves on a long trip, east or west by plane, boat or the like. This function will advance or retard the operation rate of the watch so that after a user-determined trip time has elapsed, the watch will display the actual local time at the arrival location, and the watch will resume operation at its normal rate. By glancing at the watch from time to time, a traveler can become accustomed gradually to a time change caused by his travel through different time zones so that the psychological effects of "jet lag" are minimized. The watch may also be used by a non-traveler to cause time to advance at a non-standard rate for other reasons. The watch includes a microprocessor (10), a quartz crystal (20) for providing a time standard, a display (30) for displaying the time, and a set of switches (40-90) for activating the watch's functions.Type: GrantFiled: May 7, 1990Date of Patent: February 19, 1991Inventor: Ross E.

Patent number: 4974217Abstract: A scale indicator used with an electronic setting apparatus, in which at least one of first and second indication sheets has the front surface with a plurality of scale marks and windows, and a third indication sheet rotatable from outside is arranged in 9 space between the first and second indication sheets. At least one of two surfaces of the third indication sheet is printed with characters of a plurality of series of units and numerals representing a plurality of setting scale ranges. The characters of each series of units and numerals are visible from outside through the windows by changing the angle of rotation. A single indicator is thus able to indicate a plurality of scale ranges being available for setting physical quantities and other numerical values.Type: GrantFiled: April 4, 1989Date of Patent: November 27, 1990Assignee: Idec Izumi CorporationInventor: Takeshi Inoue

Patent number: 4945521Abstract: A watch has an hour wheel (17) which can be driven in rotation around an axis of rotation (10) by a drive, and has a rotatable universal-time hour wheel (13) arranged coaxially thereto. These two hour wheels are connected to each other by a spring-loaded detent connection. The universal-time hour wheel (13) is rotatably settable stepwise relative to the hour wheel (17) by a setting element. It overcomes the spring force of the detent connection, in which connection the setting element can be coupled to the universal-time hour wheel (13) for setting the latter and can be decoupled again after the setting. The hour wheel (17) is connected to an hour hand (2), and a universal-time hour hand (3) is connected to a universal-time hour wheel (13), by which means the times of two different time zones can be indicated on a stationary dial face.Type: GrantFiled: July 21, 1989Date of Patent: July 31, 1990Assignee: IWC International Watch Co.

Patent number: 4932011Abstract: A three hand movement of the type having a frame, a stepping motor mounted in the frame, a manually actutable timesetting stem disposed in the frame and a gear train driven by the stepping motor to rotate coaxial members carrying "seconds", "minutes", and "hours" hands. An improved dual reduction gear assembly comprises a first rotatable member with a toothed wheel and a second rotatable member having first and second pinions driving the "hours" and "minutes" wheels. A timesetting gear is adapted to be clutched to the "minute wheel". A friction coupling connects the first and second rotatable members during timekeeping. During timesetting, the friction coupling slips to disengage the toothed wheel from the first and second pinions, so that the second rotatable member separately functions as a reduction gear during timesetting.Type: GrantFiled: November 6, 1989Date of Patent: June 5, 1990Assignee: Timex CorporationInventor: Herbert Schwartz
