Seiko 30 Day Winding Wall Clock Striking Day-Date Calendar 4PC-045-2

This is a 1960s to 1970s Seiko 30 Day Time Dater clock. The sticker on the back is marked Seiko 30 Day Winding Wall Clock Striking Day-Date Calendar and 4PC-451. Thus has a Seiko share movement.

The clock has a pendulum which can be adjusted to change the timing.

One interesting feature is the power indicator windows. There are two circles next to the winding arbors. They will show red when it is time to wind.

The dates are easily set by turning the date wheels.

You can see the winding key stuck in the movement from shipping. One can only wonder why the seller didn't do a better job securing it.

These movement photos are representing of the Seikosha movement from another clock. They are from a timekeeper new Zealand thread from a few years ago.

Wow, there's a lot going on there. Compared to some of the early movements this is almost watch quality mechanics.
I like the power indicators.

 

The movement photos are from someone else's clock. I didn't have a need to disassemble mine

I have the chance to pick one of these up locally but not sure of the value. It "works" but that is about it. Can someone PM me on their value?

 

What are they asking for it?

Being a 30 day spring driving the movement you'll probably get variations from fully wound to run down so you may need to time it over a number of days. It's a bit like adjusting a watch in five positions. Make a note of time gained or lost each day and average it out over the 30 days and then adjust your pendulum just a bit. If you adjust it every day you end up chasing a never ending variation.

 

Another variation. No power indicators

Interesting I'd get it Did you figure a price yet?

Here is the one I purchased. The one above is about 200 more than it is worth even with the old tag on it for $75 from the previous owner. This one was the one I originally offered. It has one scratch on the face so I offered him $50 and it is now mine. Sometimes you get a deal. Trouble is the days of the week are in Japanese! I'm not sure which day is correct!

 

That is awesome would that be called a Kanji date wheel?

One guy on a Facebook group just told me the clock is a Korean knockoff. Lol

Originally brought to the US by a woman from Japan. When she grew too old to wind it she sold it to a local clock shop. I bought it for my dad, and it hangs above my desk at work. He loves my "gifts" . We love it and take delight in it's cheery chimes.

It stopped 2 months later. I took it back to the shop in a state, running the last block shielding it from the rain. The nice lady in the storefront asked me if I had been winding it fully. Of course I had, duh. What do you think I am some sort of idiot? So she proceeds to wind it, using the key hole on the right. I had been winding the left, the chime side only, thinking it was the mainspring! So it is a heroic 60 day clock haha. I still avoid the shop and that part of downtown out of embarrassment all these years later.

It is useful as storage too, I snuck my new passport photos in there for safekeeping.

 

Ah yes, Facebook.

The source of expert opinion in many many fields .

 

He hasn't responded to my question for actual details of why he thinks it is fake. I keep telling myself that I ask for opinions and he gave his opinion so no harm.

Lol
