1. Field of the Invention
The present invention generally relates to watches, clocks and other timepieces, and, more particularly, to a watch that indicates global times.
2. Brief Description of the Presently Available Technology
Time pieces that display times in different geographical areas of the world, e.g., global timepieces, are disclosedlosed in U.S. Pat. Nos. 197,246 to Cates; 693,814 to Davis; 2,056,038 to DeAngelis et al.; 2,910,825 to Kirkwood; 3,091,915 to Pawl; 5,054,008 to Darling; 5,745,440 to Chen; and 6,243,324 B1 to Teng.
Although each of the timepieces disclosedlosed in the above-mentioned patents are acceptable for their intended purposes, there are limitations, e.g., lack of space on the dial face to provide additional and relevant information to the wearer. For example, generally world timepieces have either rotatable outer rings (e.g., Patek Phillippe style watches) or a small central rotatable faceplate (e.g., Walden style watch) both covering a portion of the dial or bezel with geographical time zone indicia using city or other name indicia. Although fully functional, the design of these timepieces limits the amount of information that can be displayed. More particularly, the dial of the presently available timepieces, e.g., analog type watches is mostly filled or obscured with time zone rings or plates, and thus there is little or no room to provide additional relevant information, e.g., displays such as chronograph (stop watch), power reserve indicator, moon phase indicator, alarm indicator, etc. Further, in the second instance, the present 24 hour world time watches do not display both days and both dates that exist simultaneously across the world and do not display which time zones are in which day and which date and do not display how the day and the date change for each time zone from hour-to-hour and do not do so in a manner to allow space on the traditional size watch face or dial for display of various other traditional information such as, but not limited to, chronograph, power reserve indicator, alarm, moon phase, and so forth.
As can be appreciated by those skilled in the art, it would be advantageous to provide a global timepiece that does not have the limitations of the presently available timepieces; more particularly, a global analog type timepiece that provides for displaying the time in all of the world's 24 time zones as well as displays additional information, e.g., but not limited to, power reserve indicator, moon phase indicator, alarm indicator, etc.
This invention relates to a world or global analog type display timepiece having, among other things, a mechanical or other type of drive mechanism to move components discussed below to, among other things, (1) simultaneously displays the world's 24 time zone times, and the two days and two dates that continuously exist across the world; (2) shows which of the 24 time zones are in which of the simultaneously existing two days and two dates; (3) shows how the day and date of each time zone change hour-by-hour and day-by-day, and (4) presents this information in a new and unique manner such as to allow easy reading and more available area on the dial to present additional other dial indicators singularly or multiply to show additional information such as chronograph (stop watch) sub-dials, power reserve indicator, moon phase indicator, alarm indicator, etc.
In one non-limiting embodiment of the invention, the global timepiece includes, among other things, a dial having an analog face adjacent a transparent time disk displaying 24 separate time zones. The analog face includes dual side-by-side date windows and dual side-by-side day windows cut open through the dial opening to expose adjacent days and dates on normal day and date rings or plates under the dial; both the two day windows and the two date windows are located on the dial astride the New Day Line defined below. A series of drive shafts or other drive mechanism is provided to rotate the transparent time disk of glass, plastic or other similar material 360 degrees once every 24 hours, and to rotate an hour hand, a minute hand and optionally a second hand. Optionally, there may be an hour hand which can be set to any desired hour, e.g., time zone, for quick and easy reference to the wearer's or other desired time zone. In the preferred embodiment of the invention, the preferably transparent disk has all of the 24 time zones indicated with either a mark or name. In addition, the transparent disk displays an International Date Line running from the disk center in a straight line to the outer edge opposite the time zone sometimes named Greenwich Mean Time (hereinafter also referred to as “GMT”) or London time zone.
The New Day Line is a line, preferably a straight line running on the surface of the dial from the center point to the midnight indice on or near the outer edge of the dial. Thus, the International Date Line on the disk will rotate over the dial once every 24 hours and will cross over the stationary New Day Line when it is midnight at the International Date Line at which moment the next new day begins, and at which time the day and date wheels both rotate, e.g., click counterclockwise which action is a part of a non-limiting embodiment of the invention not presently available on present watches having day and date windows. With the above arrangement, at any moment, with a quick glance, the reader can instantly, easily and without any adjustments, read the time, day and date of all time zones in the 24 time zones. The combination of the disk and dial provide a new and unique watch design, that provides room on the dial for various other traditional displays including, but not limited to, a chronograph, a moon phase indicator, a power reserve indicator and alarm function.
In a further non-limiting embodiment of the invention, the global timepiece incorporating features of the invention includes a case that houses a movement mechanism having a rotatable shaft. A face, e.g., a dial face is positioned immediately adjacent to the movement mechanism, with the rotatable shaft extending orthogonally through the face. An hour hand, a minute hand, optionally a second hand, and a transparent disk, suspended or positioned over and covering all or most of the dial face, are each spaced apart from one another and are each spaced apart from the face in any convenient manner. Double date face windows and double day face windows are, each pair, positioned astride the New Day Line which is a non-limiting embodiment of the invention and which extends from the center of the face to the midnight indice located on the circumference of the face. Traditional seven day (or multiples thereof) and thirty-one date wheels are set under the windows and both wheels rotate counterclockwise which is different from presently available day and date wheel watches. In another non-limiting embodiment of the invention, a bezel is rotatably connected to the outside or set inside the case or fixed with respect to the case.
In another non-limiting embodiment of the invention, the case has a pair of connectors, with each pair of connectors attached to opposing ends of the case and each pair of connectors having a first prong and a second prong spaced away from the first prong. The first prong defines a first pin orifice and an internally-threaded hollow end piece positioned at one end of the first pin orifice. The second prong defines a second pin orifice and a pinhead depression, wherein the second pin orifice is aligned along the same imaginary longitudinal axis as the first pin orifice. A pin having a pinhead, a pin shaft, and an externally-threaded end is inserted through the second pin orifice and screwed into the first pin orifice. The pinhead is moveable in a lateral direction along the imaginary longitudinal axis and contains an internal clutch mechanism, such that the pinhead can be moved in a direction away from the first and second pin orifices, and rotated in a left or counterclockwise direction. Rotation of the pinhead in the counterclockwise direction causes the pin shaft to rotate to the left or counterclockwise direction, which unthreads the pin from the first pin orifice. Alternatively, the internally hollow end piece can have a retractable, internally-threaded, spring-loaded collar positioned in the hollow end piece, and the pinhead can be integrally formed with the pin shaft.
In a still further non-limiting embodiment of the invention, the bezel can further co-define hour/minute indicia in a sixty (minute) and 24 (hour) dual unit scales so that the wearer can set the zero point to either the minute hand to time events up to sixty minutes or to the hour hand to time events up to 24 hours. The indicia can be luminescent and can also be color-coded to visually help differentiate between minute and hour readings. A pair of opposing date windows may also be defined by the case.
In still another non-limiting embodiment of the invention, the dial face can also define hour/minute indicia, as well as the New Day Line indicia. The New Day Line is preferably a straight line positioned from the center of the dial to outer circumference of the dial at the midnight indicia positioned on the bezel or the face. The face or the New Day Line can be luminescent. Additional information, such as a power consumption, moon phases, or other data, can also be included on the face.
In a further non-limiting embodiment of the invention, the transparent disk preferably floats, e.g., is mounted for rotation above the face, and preferably rotates 360 degrees once every 24 hours. In any event, the disk will allow dual day/date windows positioned astride the New Day Line to be seen through the disk. The transparent disk preferably contains International Date Line indicia; time zone indicia represented by cities or areas geographically located within each corresponding time zone and Daylight Savings Time Conversion indicia (hereinafter also referred to as “DSTC”). The DSTC indicia is an improved version in that there are indices that provide for compensation for locations that do not adopt Daylight Savings Time as well as other indices that provide for compensation for locations that adopt Daylight Savings Time opposite to the standard Daylight Savings Time months, e.g., a watch set up for reading Northern Hemisphere Daylight Savings Time as standard will have to compensate for southern hemisphere locations which observe Daylight Savings Time generally opposite to the Northern Hemisphere.
The face may be color coded to show daylight hours and evening hours, and may also be luminescent. An “A” or “P” may also be posted next to the dial numbers instead of, or in addition to, color-coding to assist in reading A.M. or P.M. hours.
An additional non-limiting embodiment of the invention includes a one to 24 hour alarm dial and function on the main dial face that is set independently of the time indicated or shown on the face of the watch, rather is set forward from the time of setting to up to 24 hours in advance which would be a feature of particular interest to world travelers who will calculate the time desired for an alarm not against the local time but against the number of hours forward for events that may be occurring anywhere in the world.
As can be appreciated, the drive mechanism of the time piece incorporating features of the invention can be powered in any convenient manner, for example, but not limited thereto, by tightening a spring, by wrist movement, or by electrical current e.g., and not limiting to, a battery, solar energy, and house current.
As can now be appreciated, the present invention allows a significant additional amount of information to be displayed to a wearer or observer not readily possible with current world time designs. For example, by including the transparent disk, the dial face area formerly covered with city or number wheels is now available for other traditional displays such as chronograph, power reserve indicator, alarm, moon phase indicator, and other information which can be included on the face. Further, watch band changes can be accomplished quickly.
These and other advantages of the present invention will be clarified in the description of the preferred embodiment taken together with the attached drawings, in which like reference numerals represent like elements throughout.
As used herein, spatial or directional terms, such as “inner”, “outer”, “left”, “right”, “up”, “down”, “horizontal”, “vertical”, and the like, relate to the invention as it is shown in the drawing figures. However, it is to be understood that the invention can assume various alternative orientations and, accordingly, such terms are not to be considered as limiting.
Before discussing non-limiting embodiments of the invention, it is understood that the invention is not limited in its application to the details of the particular non-limiting embodiments shown and discussed herein since the invention is capable of other embodiments. Further, the terminology used herein to discuss the invention is for the purpose of description and is not of limitation. Still further, unless indicated otherwise in the following discussion, like numbers refer to like elements.

Additional information, or other data, can also be included on any of the faces 14, 14A. For example and not limiting to the invention,
With continuing reference to
As can be appreciated by those skilled in the art the invention is not limited to a driving arrangement 39 (shown only in
In a preferred non-limiting embodiment of the invention, the disk 22 and the minute hand 18 occur simultaneously to set world time and are movable by one of the setting buttons KO or other activation device. The hour hand 16 is preferably actuated by an independent setting button, e.g., but not limiting the invention thereto, the other one of the setting buttons KO, to set local time. Local time can be set according to the city or time zone where the wearer is currently standing by moving the hour hand 16 to that particular city or time zone. Once set, the hour hand 16 rotates coincident with the transparent disk 22 and the local time of the city. Changing the local hour hand from one local time to another when the wearer changes time zone locations does not change the position of the disk 22, which indicates the world time because world time does not change as people move across it. Accordingly, once set, the watch time, day or date need never be re-set due to the travel of the wearer. The traveling wearer need only rotate the hour hand to the new time zone and he or she is finished.
In another and preferred non-limiting embodiment of the invention, the order is the face 14, 14A, the disk 22, the hour hand 16 (with a cut-out viewing window as shown in
Although not limiting to the invention, the hour hand 16 rotates 360 degrees once every 24 hours; the minute hand 18 rotates 360 degrees every sixty minutes, and the second hand 20 rotates 360 degrees every sixty seconds. The hour hand 16 will normally be set at the time zone local to the wearer or observer so that local geographical time can be determined at a glance. Rotation of the rotatable shafts 38-38C, the date wheel 37 (see

As noted above, the hour hand 16, minute hand 18, second hand 20, and transparent disk 22 all rotate above the first surface 30B of the face 14, 14A. The time zones on the disk are spaced from one another to correspond to the distance between the hours on the dial face. By referring to the geographical indicia 40 positioned on transparent disk 22, a wearer or observer can also instantly determine the local time of any other time zone in the world. For example and not limiting to the invention, if Tokyo (“TOK”) indicia positioned on the transparent disk 22 is coincident or points to the 0200 or 2:00 AM indicia positioned on the face 14, 14A, it is 0200 local time in Tokyo. GMT or Zulu time can also be determined by viewing the local time for London (“LON”), Keflavik, or other suitable geographically located city. Further, the wearer or observer can also determine the present day and date for all time zones by referring to the New Day Line indicia 34 (see
With continuing reference to
For watches calibrated to Northern Hemisphere Daylight Savings Time observing countries, countries located south of the equator present a more complicated DST problem. Most countries geographically located south of the equator do not observe DST, and those that do are on DST when Northern Hemisphere countries are observing standard time (“ST”). Two major southern hemisphere cities that observe southern DST are Sydney, Australia and Rio de Janeiro, Brazil. Accordingly, with this version of the watch reading the time from the perspective of the Northern Hemisphere, these locations will have the same “D” line device running to the adjacent time zone in the counterclockwise direction CCW, similar to the Tokyo and Beijing examples discussed above. However, Southern Hemisphere countries observing Daylight Savings Time opposite to the Northern Hemisphere, including Sydney and Rio de Janeiro will also have an “S” line indicia running in clockwise direction CW, one time zone to the right. The “S” line indicia indicates that during standard time in the Northern Hemisphere, Sydney and Rio de Janeiro will be on their own DST and, thus, will be one hour ahead of their regular time difference with respect to the Northern Hemisphere.
In another non-limiting embodiment of the invention, bodies 45 and/or ends 46 of the hour hand 16, the minute hand 18, and the second hand 20 can have different configuration to quickly distinguish between the hour, minute, and second hands. For example and not limiting to the invention, the body 45 of the minute hand 18 is thicker than the body 45 of the second hand 20, whereas the body 45 of the hour hand 16 has a hole in its body 45. Further, the second hand 20 has an arrowed end 46, the minute hand 18 has a pointed end 46, and the hour hand 16 has an arrowhead larger than the arrowhead of the second hand 20. As can now be appreciated, hands 16, 18, 20 can have any type of end design.
The invention also relates to a wristband connector 48 that is easy to assemble and disassemble to attach or remove, respectively, an end of the wristband from the timepiece 10. In a non-limiting embodiment of the invention, the timepiece 10 has a pair of opposite connectors 48 (only one shown in
In conclusion, the present invention provides a universal global timepiece which displays the world time in a new and unique manner including for the first time showing the world's dual days and dual dates existing simultaneously across the globe as well as show which time zones are in which day and which date and how these change from hour-to-hour and day-to-day and does so while still allowing more room on the dial than present world time watches to allow for showing additional traditional related information Whenever the wearer chooses to change watchbands, a new watchband can be quickly installed. Minute/hour indicia are generally arranged in a 60 minute/24 hour format and can be positioned on the bezel, the face, or both. The bezel is rotatable, so that when a reference point on the bezel is aligned with the minute hand, elapsed minutes can be calculated as the minute hand continues to rotate after the bezel is set and, when aligned with the hour hand, elapsed hours can be calculated as the hour hand continues to rotate after the bezel is set.
The invention has been described with reference to the preferred embodiments. Obvious modifications and alterations will occur to others upon reading and understanding the preceding detailed description. For example, the bezel and/or the locking strap pin can optionally be omitted from the global timepiece according to the present invention. It is intended that the invention be construed as including all such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
