[0018] See also Figure 1 , Figure 1 A watch with a time zone adjustment function is shown. The global time zone map can be displayed through an electronic ink screen. When the user manually adjusts the time zone, the target time zone to be adjusted is specially marked, and the time displayed on the watch is automatically adjusted to the time corresponding to the target time zone. The watch includes:

[0019] A controller 10, a time zone adjustment knob 20, an electronic ink screen 30 for displaying a global time zone map, and a time indicating device 40;

[0020] The time zone adjustment knob 20, the electronic ink screen 30 for displaying a global time zone map, and the time indicating device 40 are all connected to the controller 10;

[0021] The user adjusts the time zone by rotating the time zone adjustment button 20. The controller 10 is used to confirm the target time zone pointed by the time zone adjustment knob 20 according to the rotation information of the time zone adjustment knob 20, control the electronic ink screen 30 to mark the target time zone in the global time zone map, and synchronously control the time indication device 40 to indicate the time corresponding to the target time zone.

[0022] In this embodiment, the user uses the time zone adjustment knob to manually adjust the time zone. According to the time zone adjustment, the electronic ink screen map is updated to identify the target time zone, and at the same time controls the watch to automatically synchronize and adjust to the local time corresponding to the target time zone. The user can quickly adjust the time zone and time of the watch without complicated operating procedures, which improves the convenience of the user to adjust the time zone and check the time. In addition, the global time zone map is displayed through the electronic ink screen. Due to the low power consumption characteristics of the electronic ink screen, the watch saves power when displaying the time zone map, and can greatly extend the battery life, which is suitable for the use of watches by long-distance travelers.

[0023] Compared with traditional smart watches, the watch provided in this embodiment does not require a GPS module and uses manual time zone adjustment, which reduces hardware complexity and power consumption.

[0024] In another embodiment, the user adjusts the time zone to the current city in the current time zone by rotating the time zone adjustment button 20. The controller 10 is also used to confirm the target area in the target time zone pointed to by the time zone adjustment knob. The target area can be the current city or area where the user is located. The controller 10 controls the electronic ink screen to mark the target area in the global time zone map, and synchronously controls the time indication device to indicate the time corresponding to the target area.

[0025] In this embodiment, the user uses the time zone adjustment knob to manually adjust the target area in the target time zone. According to the adjustment of the target area, the electronic ink screen map is updated to identify the target time zone and target area, and at the same time controls the watch to automatically synchronize and adjust to the local time corresponding to the target area. The user can quickly adjust the time zone, region and time of the watch without complicated operation procedures, which improves the convenience of users adjusting time zones and regions and checking time.

[0026] The electronic ink screen may mark the target area in the global time zone map in a method of highlighting the dial position where the target area is located.

[0027] The time indicating device 40 may be a watch hand, a digital liquid crystal display, or a pointer-free indicating device including a time circle and a minute circle.

[0028] In another embodiment, see Figure 2 The watch case 100 of the watch in this embodiment is made of lightweight metal or high-strength plastic, and is waterproof and shockproof to adapt to various environmental conditions during the user's journey.

[0029] The dial of the watch adopts an electronic ink screen 30 to display a global time zone map 31. Furthermore, the global time zone map 31 can also include multiple time zone lines and a day and night dividing line. The multiple time zone lines are used to divide different time zones, which is convenient for users to view time zone information. The day and night dividing line is used to separate day and night, and is marked with different color tones, so that users can easily view the time zone information in the daytime and night.

[0030] In another embodiment, when the watch adopts a pointer-free indicating device, the time indicating device 40 includes a time circle 41 arranged on the outer circle of the watch dial, a minute circle 42 arranged on the inner circle of the time circle 41, and a time-reading mark 43 fixedly arranged on the watch dial, and the time-reading mark 43 is preferably arranged at the top center position of the watch housing, that is, the 12 o'clock position of a general watch. The time circle 41 and the minute circle 42 are concentric circles, and both can rotate around the center of the dial. The time circle 41 and the minute circle 42 indicate the time by comparing with the time-reading mark. The user reads the time by observing the alignment position of the time circle 41 and the minute circle 42 with the time-reading mark 43. The time circle 41 can indicate hours, and the minute circle 42 can indicate minutes. Compared with traditional pointers, the pointer-free indicating device maintains the simplicity and beauty of the watch dial. Compared with smart watches that rely entirely on electronic screens, the pointer-free indicating device in the embodiment of the present application can reduce power consumption, allowing the watch to significantly extend its battery life, largely meeting the needs of long-distance travelers, and the time indication is intuitive and clear, allowing the watch to retain the intuitiveness and ease of use of traditional pointer watches.

[0031] Further, see Figure 3 The watch also includes a driving system for rotating the hour circle 41 and the minute circle 42. The driving system specifically includes a micromotor 44. The micromotor 44 is connected to the controller 10. The hour circle 41 and the minute circle 42 are both connected to the micromotor 44. The micromotor 44 is used to drive the hour circle 41 and the minute circle 42 to automatically rotate and perform displacement fine-tuning at every preset fine-tuning time under the control of the controller 10, so that the time display has continuity. The preset fine-tuning time is less than 1 minute, for example, it can be 10 seconds. The fine-tuning displacement corresponds to the displacement of the preset fine-tuning time. The displacement fine-tuning can make the rotation of the hour circle 41 and the minute circle 42 not easily noticeable to the human eye, thereby improving the user's experience of viewing time. The driving system has a high-precision calibration function and can be adaptively adjusted according to the time error.

[0032] In another embodiment, Figure 2 In the embodiment, the time zone adjustment knob 20 is arranged on the outer side of the watch, and is connected to the crown 21 of the watch through a gear connection or a magnetic coupling, that is, the crown 21 is sleeved on the time zone adjustment knob 20 ( Figure 2 The user rotates the crown 21, and the crown 21 can simultaneously drive the time zone adjustment knob 20 to rotate. The operation of the time zone adjustment knob 20 is simple and intuitive, suitable for quick adjustment during travel, and improves the convenience of user operation.

[0033] In another embodiment, the user can select the time zone and region by pressing and rotating the time zone adjustment knob 20 for multiple times. Specifically, the user presses the time zone adjustment knob 20 for the first time to enter the time zone selection mode, and the user rotates the time zone adjustment knob 20 to select the target time zone to be adjusted. If the controller 10 detects that the time zone selection mode of the time zone adjustment knob 20 is activated, the controller 10 determines the target time zone to be adjusted according to the rotation direction and target position of the time zone adjustment knob 20 in the time zone selection mode;

[0034] The user presses the time zone adjustment knob 20 for the second time to enter the region selection mode, confirms the adjustment to the target time zone, and the user rotates the time zone adjustment knob 20 to select the target region from the determined regions in the target time zone. If the controller 10 detects that the region selection mode of the time zone adjustment knob 20 is activated, the current time zone is adjusted to the target time zone, and the target region to be adjusted is determined according to the rotation direction and target position of the time zone adjustment knob 20 in the region selection mode.

[0035] The user presses the time zone adjustment knob 20 for the third time to enter the region confirmation mode. If the controller 10 detects that the region confirmation mode of the time zone adjustment knob 20 is activated, it confirms adjustment to the target region.

[0036] In another embodiment, if the user does not rotate the time zone adjustment knob 20 for a preset time period after pressing the time zone adjustment knob 20 for the first time to enter the time zone selection mode, or does not press the knob for the next time, then the time zone selection mode is exited. The controller 10 is configured to not adjust the current time zone and exit the time zone selection mode if the time zone adjustment knob 20 is not detected to be rotated or the region selection mode is not activated for a preset time period after the time zone selection mode of the time zone adjustment knob 20 is activated.

[0037] In another embodiment, see Figure 4 , the watch also includes a memory 50, in which a time zone database and a calendar schedule are built-in;

[0038] The time zone database stores the time zone differences between regions in various countries and anchor regions;

[0039] The controller 10 is further used to calculate the time of the target area according to the time zone difference between the target area selected by the user and the anchor area, and the calendar schedule, and drive the time indicating device 40 to indicate the time of the target time zone.

[0040] The time of the target area includes the time difference between summer time (DST) and winter time;

[0041] The controller 10 is also used to control the electronic ink screen 30 to display the prompt information of the time difference, or control the speaker of the watch to play the prompt information of the time difference.

[0042] Specifically, the time zone database includes a global time zone distribution table, which includes major countries, cities (or regions) and their corresponding time zone differences. The time of a city or region is set as the anchor time, such as Beijing time, and the time of other cities or regions is calculated and adjusted based on Beijing time.

[0043] Calendar schedule, used by controllers to automatically calculate the current date and time.

[0044] The time of the watch is synchronized with the Universal Time (UTC), and through the time zone database, according to the target time zone selected by the user and the time zone difference, the time indicating device 40 is automatically calculated and automatically driven to adjust to the local time corresponding to the target time zone. The local time can distinguish the time difference such as summer time and winter time.

[0045] The time zone database is combined with the calendar schedule to automatically identify time changes such as summer time or winter time. If the time zone selected by the user is applicable to summer time or winter time, the system will automatically correct the time.

[0046] The watch can send a prompt message through the display or speaker to remind the user that the current time has been adjusted to daylight saving time or from daylight saving time to winter time.

[0047] In another embodiment, specifically, the time zone adjustment knob 20 can be a digital knob (Digital Encoder), which is integrated into the interior of the watch and connected to the crown 21 through gears or magnetic coupling. When the digital knob is rotated, the internal encoder will generate a digital signal, which will be processed by the controller 10 to determine the rotation direction and angle of the digital knob.

[0048] Multi-level menus and custom functions can be implemented through software programming to meet complex operations such as selecting time zones and regions. For example, a multi-level menu can be designed on the software, where the first-level menu can select the target time zone, the second-level menu can select the target region, and the third-level menu can confirm the selection result.

[0049] The digital knob is compact and can achieve high-precision rotary encoding, accurately recording the number of turns and direction of the knob. It has good waterproof performance and can meet the requirements of 50 meters underwater.

[0050] In another embodiment, the time zone adjustment knob 20 may also be a mechanical brushless encoder. A magnet is arranged inside the mechanical brushless encoder and a Hall sensor array is arranged outside the mechanical brushless encoder. When the mechanical brushless encoder rotates, the magnetic field change is detected by the Hall sensor, and the signal is processed by the controller 10 to obtain the rotation angle and direction.

[0051] Similar to the digital knob, the multi-level menu function of selecting time zones and regions can be realized through software. It has a simple structure, high reliability, strong anti-interference ability, and can also achieve high waterproof performance.

[0052] Furthermore, the watch is equipped with a solar module, which uses solar energy to power the watch, thereby extending the battery life of the watch.

[0053] The watch is equipped with a large-capacity battery, combined with the low-power design of the electronic ink screen and hands, the battery life can reach several days, which can meet users' needs for watch battery life.

[0054] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0055] The above is a description of the watch with time zone adjustment function provided by the present application. For technicians in this field, according to the ideas of the embodiments of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
