Abstract

Portable timepiece including an hour hand and a minute hand for the current time display, rotating about a central wheel facing a bezel, and also a chronograph module, wherein the timepiece further includes a first analogue trend indicator relating to a measured time interval.

First claim

What is claimed is:

1. A control or display method for a portable timepiece including a display to display a measured time and at least a first analogue trend indicator, a control interface, and an electronic circuit for the actuation of said analogue trend indicator, wherein the method comprises:
programming a first predefined time interval;
measuring a second time interval;
displaying said second time interval; and
displaying a positive or negative relative difference, which is equal to a result of taking a difference between said first predefined time interval and said second time interval and dividing said difference by said first predefined time interval, with aid of said first analogue trend indicator.

2. The control or display method according to claim 1 , wherein said programming is performed manually whereas said measuring is at least partially automatic, performed by a transponder module or a GPS module.

3. The control or display method according to claim 2 , wherein said manual programming a first time interval is correlated with the manual programming of a predefined geographical location.

4. The control or display method according to claim 1 , wherein the method includes a first programming sequence of a number higher than 1 of said programming of distinct first predefined time intervals, a second sequence of said number of measuring of distinct second time intervals, wherein
the method includes displaying, at the end of said second sequence, an overall difference between the sum of said first predefined time intervals of said first sequence and the sum of said second time intervals of the second sequence in analogue form.

5. The control or display method according to claim 1 , wherein the method includes a subsidiary setting of a difference display.

6. A portable timepiece for implementation of the control or display method of claim 1 , including an hour hand and a minute hand for current time display, rotating about a central wheel, and also a chronograph module, wherein the chronograph module further includes the first analogue trend indicator configured to display the positive or negative relative difference, which is equal to the result of taking the difference between the first predefined time interval and the second measured time interval and dividing said difference by said first predefined time interval.

7. The portable timepiece according to claim 6 , wherein the timepiece includes a second analogue trend indicator distinct from said first analogue trend indicator, configured to indicate a difference between a first sum of said first predefined time intervals and a second sum of said second measured time intervals.

8. The control or display method according to claim 1 , wherein said first analogue trend indicator includes a rotatable hand, and the displaying the positive or negative relative difference includes displaying the positive or negative relative difference with the rotatable hand.

9. A portable timepiece for implementation of a control or display method for the timepiece that includes a display to display a measured time and at least a first analogue trend indicator, a control interface, and an electronic circuit for the actuation of said analogue trend indicator, wherein the method includes programming a first predefined time interval, measuring a second time interval, displaying said second time interval, and displaying a positive or negative difference between said first predefined time interval and said second time interval, with aid of said first analogue trend indicator, the timepiece comprising:
an hour hand and a minute hand for current time display, rotating about a central wheel, and also a chronograph module, wherein the chronograph module further includes the first analogue trend indicator configured to display the positive or negative difference between the first predefined time interval and the second measured time interval,
wherein said analogue trend indicator is an additional hand rotatably mounted about said central wheel, and moving round a bezel, said bezel also including at least a first display segment representing a delay relative to said first predefined time interval and a second display segment representing an advance relative to said first predefined time interval, said first and second display segments being located on either side of midday.

10. The timepiece according to claim 9 , wherein said bezel includes a third display segment extending over a very restricted angular segment and representing a correspondence between said first predefined time interval and said second measured time interval, said third display segment being also matched with said first analogue trend indicator.

11. The portable timepiece according to claim 10 , wherein said first display segment, said second display segment and said third display segment include a reading scale formed of a series of blocks extending over an angular sector of said bezel.

12. A portable timepiece for implementation of a control or display method for the timepiece that includes a display to display a measured time and at least a first analogue trend indicator, a control interface, and an electronic circuit for the actuation of said analogue trend indicator, wherein the method includes programming a first predefined time interval, measuring a second time interval, displaying said second time interval, and displaying a positive or negative difference between said first predefined time interval and said second time interval, with aid of said first analogue trend indicator, the timepiece comprising:
an hour hand and a minute hand for current time display, rotating about a central wheel, and also a chronograph module, wherein the chronograph module further includes the first analogue trend indicator configured to display the positive or negative difference between the first predefined time interval and the second measured time interval,
a second analogue trend indicator distinct from said first analogue trend indicator, configured to indicate a difference between a first sum of said first predefined time intervals and a second sum of said second measured time intervals,
wherein said analogue trend indicator and said second analogue trend indicator are mounted coaxially about the central wheel and configured always to be superposed, except when said second analogue trend indicator indicates an overall difference over the sum of first time intervals.

13. A portable timepiece for implementation of a control or display method for the timepiece that includes a display to display a measured time and at least a first analogue trend indicator, a control interface, and an electronic circuit for the actuation of said analogue trend indicator, wherein the method includes programming a first predefined time interval, measuring a second time interval, displaying said second time interval, and displaying a positive or negative difference between said first predefined time interval and said second time interval, with aid of said first analogue trend indicator, the timepiece comprising:
an hour hand and a minute hand for current time display, rotating about a central wheel, and also a chronograph module, wherein the chronograph module further includes the first analogue trend indicator configured to display the positive or negative difference between the first predefined time interval and the second measured time interval,
wherein said analogue trend indicator is an additional hand rotatably mounted about said central wheel, and moving round a bezel, said bezel also including at least a first display segment representing a delay relative to said first predefined time inter
