Timex Electric

Post by SynMike » April 13th 2018, 2:21pm

This is my latest addition, a Timex Electric made in 1971. It is mechanical, not quartz, but battery operated. When current passes through the coil winding (balance assembly) a temporary magnetic field is created. The polarity of that field acts against the permanent magnets to kick the balance wheel around to be pulled back-and-and-forth in its oscillation by the hairspring. So an electical magnetic field replaces the mainspring as power source. Otherwise, it is all the same mechanics as a hand winder or automatic. The movement is specified to run at 21,600bph as far as I can find by readin online but the second hand only ticks 3 times per second so something is divided by 1/2 compared to most mechanicals. I'm going to research that a bit.

It was left behind at our store as non-working, not worth repair costs, without a strap, etc. He had it in a drawer for years. I brought it home to disassemble, to learn a bit. After opening it up to have a look it just started running again. The owner is long gone, it has been sitting around for a while, so I guess it is mine unless I recognize him if he visits the store again.

I have a few vintage watches but I'm picky about style and condition. This one is a style I like and the condition is pretty good. Four features that I like: the linen dial, markers instead of numbers, silver color, no date. I used polywatch on the crystal but it needs one more treatment. I found a nice strap for it (probably worth more than the watch :D ). It is running about 2 minutes fast per day so I will probably take a crack at regulating it some day. I assume regulation is actually done (can it be done?) by adjusting the electrical coil. Oh well, I'll have some fun with it regardless.

There are a few little rain drops on it in the picture. I don't have my light tent set up so I stepped out of the basement door to snap a picture. Next time my light tent is set up I'll get more flattering pictures.

That watch is in incredible shape given its age. The lack of oxidation on the hands is awesome.

Now, this is the kind of stuff that really makes this forum so much fun for me. Just great.

Marvellous watch, and the dial is fantastic too.
Here is my 1970 example, very similar but with exploding date and gold tone, on a nice vintage Apollo band.
