In order to be presented at the time of two different time zones, be provided with two

hour hands

16,17 and a minute hand, these pins rotate with one heart around an axle that is positioned at this table

center.Hour hands

16,17 preferably have identical design, thereby, if when not needing to show one second time zone, can place them in overlapping mode, the user only can see single hour hands.For easy differentiation, can make two

hour hands

16,17 that different colors is arranged, for example, under the situation here, the rounded ends of the hour hands shown in Fig. 1 has different colors.Yet, also can make two

hour hands

16,17 that different forms or shape are arranged, its mode makes when two hour hands are overlapping, those following in two hour hands hour hands are to be covered fully by top hour hands.

First hour hands 16 are adjusted these hour hands corresponding to standard hour hands of general wrist-watch continuously by means of collecting device 22.Can be used to show second hour hands, 17 operations in one second time zone by means of a button 21 that is contained in collecting device 22 tops in the horizontal.The mode of operation of this button 21 preferably makes, under any circumstance, down clicks second hour hands and can march forward one hour.Only adjust with direction forward.Like this, if for example second time zone is set to, for example the New York local time (6 hours backward), just must the button 21 of second hour hands 17 be started or push 18 times.When second hour hands 17 being set at a specific time zone, two

hour hands

16,17 move abreast, that is, with the unequal angular velocity motion, and same minute hand 20 show two time zones minute.Two

hour hands

16,17 adopt the same index dial 13 that has 12 hours, and therefore two hour hands have ambiguous part (for example, for 6 o'clock mornings and at 6 o'clock in afternoon, the position of hour hands is identical) on time showing.

Can be fast and easily read time in another time zone in order to make usually the user in one of two time zones that set, relevant with each hour hand or each time zone also have a

display device

23 or 24, and they are presented in this specific time zone is daytime or night.Basically, for this purpose, 24 hours one day can be divided into plurality of sections (for example four sections of 6 hours).Therefore,

display device

23,24 is presented at which section the time is in the relevant time zone.For simplicity, the best the 3rd or the

4th display device

24 or 23 is divided into two fixing half a day to a whole day of 24 hours, comprises from 6 o'clock mornings to afternoon 6 o'clock time first half a day, comprises second half a day from 6 o'clock in afternoon to morning 6 o'clock time.For this purpose, in each case,

display device

23 and 24 is provided with a window (in Fig. 2 28) on index dial 13, it is shaped as the part of annulus, the user can see a fan-shaped disc being arranged in below it (Fig. 2 29) by this window, this disk below window with its optically different sector rotation.

In Fig. 2, show an exemplary driving mechanism (there is similar structure in the mechanism that is used for display device 24) that is used for display device 23 with the form of amplifying details.The gear 25 of a tooth punching is connected with the driving mechanism of hour hands 16, this gear is to rotate (circling in 12 hours) with the hour hands unequal angular velocity, the structure of the gear 25 of this tooth punching is a spur gear, it engages with the gear edge 26a of a cam 26, rotatably and axially go up parallel mode and this cam is contained in the next door (for simply, in Fig. 2 only with this tooth of circle expression of dotted line) of the gear 25 of tooth punching.The diameter ratio of the gear 25 of tooth punching and gear edge 26a is chosen to obtain a ratio of gear of 1: 2, that is, cam 26 is with the angular velocity rotation (circling in per 6 hours) of the twice of the gear 25 of tooth punching.This cam has a flange 27 at some place of its circumference, it is stretched out by this circumference, and, when this flange rotation during through an adjacent parallel in the axial direction geneva gear 31, to engage with this geneva gear, make this geneva gear 1/4th weeks of rotation for whenever circling of it.This cam 26 and geneva gear 31 have constituted a cross wheel drive unit together, show this device with the details of amplifying in Fig. 3.Geneva gear 31 is arranged on the common axle with a fan-shaped disc 29 that is in its top.Fan-shaped disc 29 preferably has four sector 28a-d with 1/4th forms, is having any different on the image or on the color (representing with hacures in Fig. 2) in these sectors.In each case, make two adjacent sectors (30a and 30b or 30c and 30d) keep identical on the image or on the color.Fan-shaped disc 29 be set at window 28 in the index dial 13 below, its mode makes at the neutral position of this disk, can only see one of sector 30a-d between the handoff procedure in window 28.In Fig. 2, in window 28, can see sector 30b.If suppose to have the sector 30c and the 30d of (dark) of hachure to represent to the night between 6 o'clock mornings half a day in the at 6 o'clock in afternoon, and (bright)

sector

30a and 30b represent 6 o'clock mornings to another half a day between at 6 o'clock in afternoon, so in relevant configuration shown in Figure 2, first of the afternoon of first hour hands 16 in one day be in half, promptly in the morning 6 o'clock between high noon.Fan-shaped disc took place by the switching of a sector to next sector in per 6 hours, actual handoff procedure carries out half an hour.Fig. 4 shows each stage of such handoff procedure.To Fig. 4 e, cam 26 has rotated altogether 30 degree by Fig. 4 a, and under the situation of the rotational speed of changeing for 1 week in per 6 hours, this is equivalent to 30 minutes the time interval (per minute changes 1 degree).The flange 27 of cam 26 begins after 5 minutes from the position of Fig. 4 a, or engage (seeing Fig. 4 b) with geneva gear 31 after rotating 5 degree, and after below 10 minutes, or make this mechanism's rotation 45 degree after rotating 10 degree, forward the centre position shown in Fig. 4 c to.(Fig. 4 d or 4e) reaches endpoint location after another 10 or 15 minutes, and in this position, this geneva gear has rotated 90 degree.Like this, the user of this wrist-watch can easily determine when to occur in the change of time period in 6 o'clock mornings and at 6 o'clock in afternoon one day, or when the sun rises and fall.
