Description

Countdown device for watches

Technical field

The invention relates to the technical field of smart watches, in particular to a countdown device for a watch

Background technique

1. Countdown is a function that is often used in daily life. The countdown function is different from the chronograph function. The chronograph function is a common function in the watch function, but the countdown function is not easy to implement in a conventional watch due to complicated operation, and generally only appears in a smart watch.

The invention relates to an implementation manner of a watch countdown function, which can realize the countdown function of the watch in an ordinary watch, and the operation is simple and convenient.

2. Currently, the countdown on the market can be divided into two forms:

One is a full-mechanical device. By manually rotating the turntable, the time is set by the scale and the angle of rotation. After the hand is released, the setting is completed, the countdown starts, and the turntable is rotated. When the turntable is turned back to the original position, the countdown ends.

The other is that the software is added with the screen to set the time through the interactive interface, and the software timing is determined after the start. On the smart watch, it is by sliding the touch screen of the watch to operate the interface and set the timing. After the countdown is over, the watch vibrates or alerts the user with a sound.

3. The first mechanical to timing device has the advantage of being simple to operate and easy to understand. The disadvantage is that it is bulky, not suitable for watches, and the size is reduced by a factor of ten to be placed in the watch. How to achieve in the watch, but also to ensure the use of experience and product quality, while not affecting the aesthetics of the watch is very difficult.

The second method, which is implemented by touch screen and software, is good, but requires a touchable screen or an operation button, which is unsatisfactory for a conventional watch. In addition, due to intelligence The watch has many functions and many operation steps, which will directly reduce the user's willingness to use the countdown function.

The difficulty in solving this problem is that the implementation method should be applied to ordinary watches. The operation should be convenient and fast. The weight and volume of the watch cannot be changed much without affecting the appearance and wearing comfort of the watch. Guaranteed service life, not lower than similar general products.
