My new wrist watch
I bought a new wrist watch. The old one was about ten years, it's a mechanical watch.
Recently, when I need a exact time, it sometimes stopped or it often showed un-correct time.
The brand name of a new watch is SEIKO LANDMASTER (SBDW005). It generates electric power by wrist movement. When I move my arm, the electric power is generated, and accumulates the electric power in the watch, and it transfers the watch movements. The body of the watch constructs monolithic container that has no lid in the back because it's no need to change a battery. The materials of the body is mainly titanium.
I like it!
