    This is a regulator I’m considering purchasing and I’ve never heard of Toyo Mark and I don’t know anything about it. Can someone identify it?

    The clock is Japanese.

    The trademark is identified, but the owner of the trademark is unknown according to Charles Davis' website.

    Mikrolisk identifies it as belonging to Hibino. Davis' website has a similar but different trademark for Hibino.

    So, the clock could have been made by Hibino or by an unknown maker.:?|:?|

    Regards.

    How can I tell if this is a 31 day clock? I try to stay away from 31 day clocks because of all the horror stories I’ve heard!

    I have never owned a Japanese or Korean clock, but Japanese clocks of pre-WWII vintage, whch I believe is the time period of the clock you pictured, are usually of high quality based on the comments on this board of their owners and of those who have worked on them.

    Korean clocks tend to be of more recent vintage and the opinions on their quality is mixed.

    Others will contribute their experiences.

    Regards

    I wouldn't say "high quality", more like just OK quality. :)

    The older ones are typically 8-Day, the later ones 31-Day. The change was approximately in the early post WW-II period.

    The horror stories about the springs are a myth. The springs (at about .0155") are average in strength but they are about 50% longer than other American style clocks. That's right, they are mostly close copies of American clocks. As always, there are exceptions.

    You are probably aware that the word "regulator" has meaning but this clock, in no way, falls into the regulator class of clocks.

    So it appears this is a Korean 31 day. The movement is unmarked. It also appears that the horror stories are most certainly not a myth, because as feared, one click is completely destroyed and the other is only holding on by a few thousands of an inch.

    I guess I don’t know for sure that this is a 31 day, but in any event after seeing the movement I don’t know if I’ll be interested in fixing it.

    I don’t suppose anyone reads Korean? I’m curious what the handwriting says!

    That's a pretty good movement and it's easy to repair. It's patterned from the famous Ansonia 'Pacemaker' series. Clicks do break but this is not due a spring with magical superpowers. Ha More likely caused by poor winding habits, or forcing the wind in the wrong direction.

    Yes not any more hazardous to work on, Just longer main springs to contend with.

    Ok, thanks guys. I suppose I’ll tear into carefully then. The time side click is just barely together, so I’ll be mindful of that as I go.

    I'd zip tie the heck out of both of them while winding to secure with a clamp.

    When the click/s are bad you can wind the springs easily with most modern cordless drills. The drill has to have a variable speed, with hi/low setting and a automatic brake.

    You will also need an adaptor to connect your drill to the key or winding square. If you have the usual set of letdown tools, you can use your drill, with a deep well 7/16" socket and the correct letdown tool bit.

    I can make a photo, if this description is not good enough. With this set-up ...
    We don't need no stinking clicks! :)

    That’s perfect! Thanks for the tip Willie!

    I had the text translated and it’s the address to a watch shop in Daegu, South Korea. Perhaps this actually is Japanese and was sold at one time in that watch shop? I can’t see why they would have dismantled a new clock to put their shop address behind the movement?

    A lot of clocks, like your clock, were shipped back to the US by soldiers before, during, and after, the many years of conflict in the area.

    Also (later) large numbers of old, and not so old clocks, were shipped to the US by antique importers.

    The 'tell' on many older Japanese clocks is the case size. The movements are normal size but the cases are about 3/4 scale ...

    Can someone tell by looking if this is indeed a 31 day spring? It doesn't appear any longer than the 8 day American springs I'm used to seeing.

    Overall, the movement was remarkably easy to work on and actually in very good shape minutes the damaged clicks. I think I'll definitely enjoy this clock once I hang it after all! :)

    I would say an 8-Day. You can pull it out and measure it to be more certain. An 8-Day spring will be around 96" long. A 31-Day spring will be around 155" long.
