Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and exemplary embodiments.

Fig. 1 is that line points to a hour dial plate synoptic diagram of 24 o'clock of dish when striding bu.The outer ring is the every minute and second dish, and digital 5-60 represents the minute, second reading.Centre circle is little hour indicator, 1 to 24 expression hour reading, so right side 24 to 12 is expressed as point in the morning 0 to 12 on the dial plate, left side 12 to 24 is expressed as point in afternoons 12 to 24.Inner ring World time disk 0 to+12 and 0 to-12, expression world time zone.± 12 time zones line when striding bu, it is the time on the same day that this line rotates formed fan-shaped time corresponding with line from the dial plate center to hour dial scale 24 along digital augment direction, all the other are time the previous day.This figure hour indicator ± 12 time zone timesharing lines are positioned at 24 points, so the time that whole time zone is represented is the time on the same day.So because the effect of minute hand, second hand did not draw with there be not change in the past.

Fig. 2 is that line points to a hour dial plate synoptic diagram of 3 o'clock of dish when striding bu.+ 9 to ± 12 time zones are the time on the same day.Time corresponding is 24 points, 1 point, 2 points, 3 points successively.All the other are time the previous day.The corresponding time and the like.

Fig. 3 is that line points to a hour dial plate synoptic diagram of 12 o'clock of dish when striding bu.The time zone that promptly is positioned at the dial plate right side at present is the time on the same day, and the time zone that is positioned at the dial plate left side is the time of the previous day.Time read and time zone reading fit like a glove.

Be example again with Fig. 2, time zone such as the BeiJing, China is+8, the time zone of Amsterdam, the Netherlands is+2, in Fig. 2,23 of+8 corresponding little hour indicators, promptly Beijing time is points in evenings 23 (minute hand and second hand do not draw, and give an example with integral point) now, so+2 17 of corresponding little hour indicator, promptly the time of Amsterdam, the Netherlands is points in afternoons 17 now.Because+8 ,+2 all when striding bu line rotate outside the formed sector region along digital augment direction with line from the dial plate center to hour dial scale 24, so BeiJing, China and Amsterdam, the Netherlands be on the same day, and line and line from the dial plate center to hour dial scale 24 have been second day all along the time zone that digital augment direction rotates in the formed sector region (Fig. 2+9 to ± 12) when striding bu.

How a circle was changed into 24 hours in 12 hours: in Fig. 4, do following change on the basis of analog timepiece, first hour hands change World time disk into.It two is that the time that World time disk turns around is 24 hours.Can not change basically under the situation of original analog timepiece use habit like this, realizing time showing from single time showing to universal time.Differed a circle because of 12 hours with 24 hours,, be twice so the afterbody transmission speed ratio adds so world's hour indicator rotating speed is ordinary clock and watch hour hands rotating speed half.Showed that clock and watch hour hands afterbody transmission speed ratio was 4 in 12 hours, so showed that the last transmission speed ratio of clock and watch should be 8 in 24 hours.Gear train is that 8 tooth driving wheel A drive 32 tooth engaged wheel B, and the 16 tooth ratio wheel C of fixedlying connected with engaged wheel B drive 32 tooth engaged wheel D, and the 24 tooth ratio wheel E of fixedlying connected with engaged wheel D drive 24 tooth engaged wheel F.This part body speed ratio is (32X32X24)/(8X16X24)=8, and so just having realized slowing down and keeping hour hands is former turning to.

The installing space of newly-increased two groups of gears is solved by the World time disk shield portions by removing former dial plate.New dial plate is an annular, and numeral is constant with the scale part.This segment thickness is one millimeter.Two groups of gear thickness are no more than 0.7 millimeter (original gear thickness is 0.2 millimeter).So can guarantee newly-increased two groups of gears installing space is arranged.
