Who Is The Maker?

[Michael Morgan]

I need to know if anyone knows who a maker is that uses a triangle with a large "S" in the center of the triangle with a smaller "H" in the middle of the "S" for their maker's mark? This mark is embossed on the rear plate of the movement. PLEASE HELP!!!!!!!!!

It would help if you could post pictures of the movement, case and trademark. Pictures are much easier to identify than verbal descriptions.

Best,

Thanks, Richard. I will post a pic.

Sounds like a Seikosha to me Japanese made.
Pictures always help.

I can't put my hands on it right now, but I recall seeing the logo you describe. It appeared to be Japanese and also had the logo on the back. This is very unusal with Japanese clocks which, for the most part, are always fastened to the back board. It was some time before I saw the adjacent stamping that read Korea. I would imagine that this indicates post WWII and prior to the Korean War which divided North and South.
So may questions and so few answers!
