Problems solved by technology

This display method requires two mechanically driven discs, and is only differentiated by the tens digits, not the entire time display
[0007] Most of these displays fall short of the elegant aesthetics of some watches

Embodiment Construction

[0026] refer to figure 1 , the analog wristwatch 10 with a calendar according to the prior art includes a small window 11 in which a date 12 is displayed. The number 28 in this figure represents the 28th day of the month. The date is for example written in dark letters on a light background. The hour hand 13 is at 10 o'clock, and the minute hand 14 points to approximately 10 minutes. Just looking at the dial of the watch 10, it is impossible to know whether it is 10:10 or 22:10. In other words, it is impossible to distinguish between AM time and PM time. Therefore, the user may make a mistake when setting the time of the watch, thereby making the date change 12 hours ahead or 12 hours behind.

[0027] According to the data of the present invention, for example the method of displaying the date can remedy this defect by displaying the date in a manner contrasted with the background of the display window, in this case using a liquid crystal or similar digital display, and in...

Abstract

The invention relates to a method of displaying the date on an analogue watch and the watch using this method. This watch (40) comprises two hands for displaying the time (43, 44), a time- and date-setting winding crown (45) connected to a time-setting stem, a first screen (41) for digitally displaying the date and a second screen (42) for digitally displaying the time in a second time zone by means of an EPD-type liquid crystal display, and a microprocessor designed to control all the functions of the watch. The display of the date and the time in a second time zone is made to contrast with the background of the display screens (41, 42), and the contrast is reversed at midday and at midnight to differentiate AM time from PM time. This contrast inversion is controlled electronically by the microprocessor of the watch.

Description

technical field [0001] The invention relates to a method for digitally displaying time-related data, such as time information or a date, on at least one digital display of liquid crystal type or similar on an analog watch comprising at least two hands for displaying the hours and minutes, a time regulating crown (couronne) connected to the time and date regulating lever, a microprocessor that manages all the functions of said watch. The method displays the data in contrast to a background of the digital display. [0002] The invention also relates to an analog wristwatch comprising at least two hands for displaying hours and minutes, a time-date adjusting crown connected to a time-adjusting lever, digitally displaying the time-related by display means of the liquid crystal type or similar at least one display screen for data, a microprocessor that manages all functions of said watch. In order to carry out the method, the at least one display screen displays the data in contr...
