In various embodiments, such elastic filaments are also referred to as "snap springs," "wave expansion tabs," "wave expansion springs," "C-springs," and "C-springs. Also known as a retainer ring or snap ring, is one type of fastener for mounting in a shaft or bore slot of a machine or device and serves to prevent axial movement of a component on the shaft or bore.

The wearing assembly 3 is mounted to the housing 1 in a watchband or a watch chain shape.

Specifically, a standard interface is reserved on the shell. The standard interface includes, but is not limited to, a charging interface and a data interface.

Specifically, the shell is provided with noctilucent decorations.

Specifically, prevent falling on the shell, strengthen waterproof, prevent scraping and second piece display screen structure.

In the invention, the watch core can adopt the mechanical watch core assembled in the prior art, and can also select a quartz/electronic watch core. When the mechanical watch core is used, the power source is a crown 4 screwed on the string so as to provide power for the walking of the mechanical watch core, and when the quartz/electronic watch core is used, the power source is a built-in power source so as to provide power for the walking of the watch core, and the watch core has the characteristics of water resistance, vibration resistance and the like and is not described in detail herein.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
