I am curious where this Ball Watch Co. electric clock might have been used, it has a wiring diagram on the back that shows the clock could be hooked up to a Simplex Time Signal control, I would guess similar to the ones used by Western Union to synchronize there clocks.

Thanks

Thanks Lindell

I will post more later, I just received the clock in the mail today & will take a better look at it.

It looks like this clock dates to sometime after 1940, I was able to find the patents for the numbers listed on the back & they were applied for in 1938, 39 & 40.

The clock has a dial diameter of approx 13" & the brown metal case is 14 1/4".

The glass is a dome shape & is made of glass, it is held in place with a spring.

I removed the glass & the dial is paper stuck to a metal backing, I assume it is original but can not say for sure. The dial has a few brown marks on it, I am not sure if they were caused by sun light or what.

This is the Ball marks

At the top of the dial these numbers are visible.

On the right side of the movement is apparently where the sync lines were connected.

I have had it plugged in & running for several hours now & it seems to keep very good time, it is also the quietest electric clocks I have ever had, most of them seem to hum loud, this one I can't hear running.

After taking a good look & this clock & speaking to Lindell by phone, he & I got to wondering if this was perhaps a home made dial on the clock. It had some inconsistencies, the dial cut near the top & what appeared to be a crease near the center.

This evening I was able to remove the dial & sure enough someone made the dial & placed it over the original Simplex dial. It looks like it was done quite a while back & it actually looks like it was hand drawn.

The seller who I bought this from has agreed to refund my money, I don't think it had a clue about the dial being fake, he had purchased this from a retiring watchmaker along with other things.

So I learned a lesson here, if it is worth faking someone will.

Those hands sure look like the old IBM electric clock hands I used to stare at day in and day out in elementary school, which used a synronized system connected to a master clock located in the school office next to the principles secretaries desk. Bit thick hour hand, and narrow minute hand.

I remember those hands well. MAN that was a long time ago, but I remember those clocks well! (grins)
