they are loose right from the factory.
The rotor is kept (roughly) in the center by a riveted post running in the hole of a bridge, and three plastic heads keep it (roughly) in parallel to the plate. And the ingenious is: The more shake the post gets in its hole due to wear, the more efficient the rotor winds the watch.
The mechainsm is described here

and I can't help, I've never seen a more sophisticated automatic design.

Nice work! Here's my two that I got working:
That is great and you too have one like mine with what looks to be the original strap. Can it be that these Electrics hold up better over time then quarts watches?

"Forever is composed of nows." - Emily Dickinson
"The watch has to be surrounded by a history.
You need more than just a great design. You need to create an atmosphere around the product.
Who is the company behind it? Why are they using this material?
People need to be able to identify the watch with themselves. It's based on emotion." - Ralph Furter
...that's just my opinion and I've been wrong before and will be again and might be now!
Somtimes the rotor does actually get a little loose. Older models from the late 1950s make more noise than the Timex automatics from the 60s and 70s. I know that some of my friends on the Timex Forum would try to stake or punch the rivit to make it tighter. While I have never tried that, I have on occasion "super-glued" the weight back on to the rotor assembly of a few Timex. I know a lot of folks make fun of Timex, but they are a great watch for a beginner to get experience/confidence in working on watches. I personally started on Timex, and then moved on to higher grades of wrist and pocket watches, and clocks.
Timex Electrics are a pain because they wear out in strange places. Check out the wear on this one:
Also they come in so many cool styles. Here are a few of mine:
The one on the bottom right was designed by Richard Arbib, who designed many watches like the Ventura and Pacer for Hamilton (according to his son, who emailed me in hopes of buying mine). Also, you'll notice the tiny dot above or below the number in the date window denotes AM or PM.
Those automatics sure sound fun. After reading what you have to say about them I'm not to sure about diving into them just yet. :)
The one bottomn right is a model 67 right? I actually have one of those (West Germany) laying on the table waiting for me to test it's fuinktionality but should I be extra careful with this model?
The AM, PM dot was new to me and nice to know.
I also have a really fat Electric (Oops that was a big fat dynabeat) but haven't looked closer at it yet because it's lost it's battery cover.
Vintage Timex are masters of design and especially their dials (just look at yours...wow) are second to none and i just love them to bits but I'm no collector so I will fix em then ship em...After using them for a awhile first of course. :)

bidfun-db Archive: Watch Movements: Durowe 861
When this first German electrical wrist-watch calibre was produced, Laco/Durowe already belonged to Timex, but early samples of these watches were still signend as Laco on dial and movement, and came with this particular case like this one: bidfun-db Archive: Wrist Watches: 247: Laco Electric Dynabeat, First German Electrical Wrist Watch, 1961
Many believe that Timex bought Laco/Durowe to have a quick start with electric movements. And it can be regarded as proof that they passed the mechanical-movement division (Durowe) to Switzerland pretty soon.
@Shum:Don't worry, except the delicate contacts this movement is bulletproof.Originally Posted by Shum

Just curious, is my Dynabeat in any way different from the regular Electrics? Just a model name or actually different. This is an interesting thread. And by the by, RonD, I think that watch designed by Arbib is great. The blue Marbled dial is nice too.
Yeah the dial has a linen look to it. I do believe the date on this is from around 1961. I think it has 11 jewels. You may notice that those were back-sets. I always liked wearing them and having someone ask me "how do you wind it, or set the time? lol
Roland, I am not 100% sure of the designer.. but did have many emails from a guy who said his father designed it. I suppose it is possible. If you do a search, you can see where Arbib designed cars and other items.
