Title: Time zone setting device

Description:
FIELD OF THE INVENTION  
       [0001] The present invention relates to a watch that includes a memory and a control device so as to set date and time of different time zones.  
       BACKGROUND OF THE INVENTION  
       [0002] A conventional watch is designed for showing time and date for the users. However, only the information of one time zone can be shown and this is not ,satisfied by the users especially for those who travel a lot. The conventional watch has to be adjust the time and date when he/she travels from one place to another. A reverse operation action is proceeded after the user travels back to the original place. In addition, the user has to memorize several time laps of the time zones so as to adjust the watch.  
       [0003] The present invention intends to provide a watch that has an operation panel connected to a memory and a CPU so that the correct time and date of a desired zone can be shown on the watch.  
       SUMMARY OF THE INVENTION  
       [0004] In accordance with one aspect of the present invention, there is provided a time zone setting watch which comprises a case with a dial and a circuit board received therein. A display device and an input device are located on the dial. The input device including buttons is accessible from outside of the case. A clock generating device and a quartz oscillator are connected to the circuit board. A CPU is connected to the circuit board, the clock generating device, the quartz oscillator, and the display device. A memory is connected to the circuit board and the CPU. A power supplies electric power to the circuit board, the display device, the input device, the clock generating device, the quartz oscillator, the CPU and the memory.  
       [0005] The primary object of the present invention is to provide a watch that has buttons which is operated to activate the CPU to display time and date of a specific time zone.  
       [0006] The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
     [0009] Referring to FIGS. 1 and 2, the time zone setting watch  1  of the present invention comprises a case  10  with a dial  11  and a circuit board  100  received in the case  10 . A display device  13  is located on the dial  11  and includes several windows to show different information such as date and time. A watchband  14  is connected to the case  10  such that the watch  1  can be worn on the user&#39;s wrist.  
     [0010] An input device  15  is connected to the dial  11  and includes an option button  151 , an adjust button  152 , and a confirm button  153  on the surface of the watch. The three buttons  151 ,  152  and  153  are accessible from outside of the case  10 .  
     [0011] A clock generating device  16  is connected to the circuit board  100  and provides clock information to a CPU  18  connected to the circuit board  100 . A quartz oscillator  17  and a memory  19  are connected to the circuit board  100  wherein the memory  19  stores information of different time zones. The CPU  18  is connected to the circuit board  100 , the clock generating device  16 , the quartz oscillator  17 , and the display device  13 . A power supply (not shown) is connected to the circuit board  100 , the display device  13 , the input device  15 , the clock generating device  16 , the quartz oscillator  17 , the CPU  18  and the memory  19 .  
     [0012] As shown in FIG. 3, the quartz oscillator  17  is connected to the display device  14 , and the CPU  18  is connected to the clock generating device  16 , the quartz oscillator  17  and the display device  13 . The memory  10  is connected to the CPU  18 .  
     [0013] A instruction signal is sent to the CPU  18  by operating the input device  15  and the quartz oscillator  17  picks the signal from the input device  15  to the CPU  18  which picks specific information in the memory  19  and the picked information is displayed in the display device  13 . In addition, the CPU  18  picks the information of the clock generating device  16  and the information in the memory  19 , calculates the two information and displays the correct time and date of the time zone of the chosen city or country.  
     [0014] The user may choose alarm mold, present time mold, or country or city mold by using the option button  151 . The CPU  18  is then activated to display the chosen information on the display device  13 . The adjust button  152  is used to input an adjust signal to the CPU  18  to adjust the information of the alarm, the present time, or country or city. Every time a signal is sent to the CPU  18 , the confirm button  153  has to be pressed to switch another mold.  
     [0015] When the alarm mold is set by operating the option button  151  and choosing the information displayed in the display device  13 , the confirm button  153  is pressed. The digits on the display device  13  is flashing and then the adjust button  152  is pressed to change the digits. The confirm button  153  is pressed again to set the digits. By the process, the digits on the display device  153  can be set one by one.  
     [0016] The present time can be adjusted by first pressing the option button  151  to choose the present time mold. The digits are flashing one by one and changed by pressing the adjust button  152 . The flashing digits are set by pressing the confirm button  153 .  
     [0017] The country or city mold can be chosen by using the option button  151  and the CPU  18  provides names of country and city from the memory  19  to be chosen in the display device  13 . The alphabets are flashing and can be adjusted by using the adjust button  152  and be set by using the confirm button  153 . When the country or city is chosen, the corresponding time and date of that country or city are shown in the display device  13 . Therefore, the user may switch the time and date from one place to another by simply using the buttons  151  to  153  on the case  10 .  
     [0018] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
