Embodiment Construction

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0050] The embodiment of the invention discloses a watch to solve the problem of poor travel time accuracy of the mechanical watch.

[0051] In the watch provided by this embodiment, its travel time system includes:

[0052] Winding mechanism powering the seconds, minutes and hours hands;

[0053] a power transmission wheel train matched with the winding mechanism to drive the second hand, minute hand and hour hand;

[0054] The power source device, the travel ti...

Abstract

The invention discloses a watch. A timing system of the watch comprises a clockwork mechanism for supplying power to a second hand, a minute hand and a hour hand, a power transmission gear train which is matched with the clockwork mechanism and drives the second hand, the minute hand and the hour hand to run, a power source device, an electronic transmission gear train, and a mechanical transmission gear train which is connected with an escape wheel of the power transmission gear train, wherein a timing motor of the power source device drives a rotor to rotate; the timing precision of the timing motor is controlled by quartz; the electronic transmission gear train is connected with the rotor; the rotor rotates to control the electronic transmission gear train to run; the escape wheel rotates to control the mechanical transmission gear train to run; and an intermittent movement transmission is adopted between the mechanical transmission gear train and the electronic transmission gear train, namely the running precision of the power transmission gear train is controlled by the electronic transmission gear train. The hand running precision of the timing system of the watch can reach the precision of a quartz watch.

Description

technical field [0001] The present invention relates to the technical field of timepieces, and more specifically, to a watch. Background technique [0002] At present, there are generally only two types of watches on the market, one is a mechanical watch and the other is a quartz electronic watch. The mechanical watch has a superb technical structure. The constant swing of the balance wheel and the continuous beating of the second hand make people feel the passage of time. At the same time, the movement of the internal parts of the watch movement gives people an elegant aesthetic feeling, but the biggest flaw of the mechanical watch is the travel time. The accuracy is poor. At present, the travel time accuracy of watches with tourbillons is difficult to control within 5 seconds per day. Contents of the invention [0003] In view of this, the present invention provides a watch to solve the problem of poor travel time accuracy of mechanical watches. [0004] In order to so...
