Post #19 Seikosha mainspring pendulum clock

Bought this from an antique retailer for approx. US$40. Seikosha (精工舎), as most of you may know, is more or less the R&D and manufacturing roots of the present Seiko brand. The company was established in 1892, demerged from K. Hattori (服部時計店). According to the retailer this particular model is from the late 1930s. The tanned paper dial, the fonts etc. gives out a cozy and retro aura, yet fits perfectly well with my relatively modern home. Only problem is the noisy gong, so it’s hooked up on the entrance wall.

Correct me if I'm wrong, but isn't one winding arbor for the main spring and the other for the bell strike mechanism? If one wants a clock that does not strike the hour (or more), one need merely not wind that arbor. Of course that leads to a problem getting it synchronized should one want it to strike in the future, but that's not too difficult.

So motion can be seen through the aperture above the 6?

You are right. In the excitement of the purchase I was stupid enough to wind both. I ‘ll have to think of a relocation once the left side is unwound. And yes, motion can be seen through the opening above 6.
