Default Red Star WW

I have this Red Star watch and don't know much about it, or even if it is a Japanese watch. I've had this for a month or so and just got around to looking inside, and found what is shown in the attached images.

I've had it in a box, and just now tested the battery...very dead. And yet, the movement is keeping good time. With the battery out.

The movement is a printed circuit board with the i.d. of R2647C. It is marked B16 on the case back. It has some LCD displays on the dial, which I haven't been able to get to work, nor can I find anything online about it.

Anyone have knowledge of this type of watch, and...what makes it tick?

Red Star Watches👍
Built on many years of watch manufacturing heritage and tradition, a small but elite group of fine watchmaking companies from mainland China, such as Red Star, Sea Gull and others are quietly producing an increasingly wide range of high-quality timepieces.


Not much else on them I can find anyway but they do Mechanical watches as well so I assume a range of Autos.

interesting that the movement is still running without the battery, that would suggest some kind of independent storage such as a capacitor or even solar?

Or, under the circuit board lurks a small ladies quartz movement with another battery
(Seen it before)

I've found that with a few watches. A friend's one has a lithium battery for tide times and under it is a small battery for the time section.

Well, you were right...there was a second battery beneath the printed circuit board. That battery runs the plain old quartz movement, and the larger CR2016 battery runs the LCD stuff on the dial. I'll replace both and see what I end up with.
