There have been several watches out there with plastic parts, including, I think, some Omegas. There are some advantages to plastic in being self-lubricating and not wearing down (not that's it's always a good thing). I'm not sure which particular movements, but here are a bunch of threads - and there are more if you search :

I think the Omega Speedmaster with 1861 movement had a plastic blocking lever in it. The 1863 movement did away with it

Those plastic parts are not in the drive train, but on the calendar complication, so, technically, this does not fall under the restrictions of this thread.

Neither do the 7750, the Omega, or the LEM 5100, which have plastic parts in the chronograph complication.

Very few movements have plastic in the drive train.

You make a good point...none the less I welcome any information so that it can at least be documented and discussed.

The ETA 2841-1 has a plastic pallet fork and escape wheel. You can clearly see it in the Swatch skeleton watches such as the "body and soul" and the "uncle charly" ( the latter of which I own) if you look closely through their crystal.

Not being particularly knowledgeable about these things, I had some reservations about getting a sistem51 following the very averse reactions I witnessed posted in a blog article in which revelation of the same plastic parts in that movement was pointed out. Then I go looking on the web and discover that there are "proper"movements with the same plastic drive train parts that nobody seems particularly perturbed about.

So, as far as plastic is concerned, I find no evidence thus far that metal parts of this type are superior to plastic, or that some plastic parts in a movement make it inferior. I stand to be corrected of course.

Both sides of metal versus plastic has been discussed ad nauseum on this forum.

My belief its just a marketing gimmick...one day in the future I am sure they will use "all metal" as a selling feature. In the meantime, plastic parts allow the them to market more accurate watches with longer power reserve as a today's latest and greatest selling feature.

Personally, I would rather take my chances with all metal.

Thanks for that insight, pjviitas. Last thing I want I to fire up a stagnant debate in my blissful ignorance. I must say, I also rather fancy the idea of a nice SEIKO automatic. Heck, I fancy a Zenith El Primero 1969 original, but that's lot of cash for a watch.

I did go and buy a system 51, the Chic. Fascinating watches, truly unique. Whatever happens, I own a piece of watch history.

I've been doing a bit more reading, and I think one might be incorrect in labeling such parts as escape wheels and pallets/forks as "plastic." It does seem that in fact, what might be in use is DRIE (deep reactive ion etching) etched silicon that is coated with carbon. Some of these "plastic" escape wheels certainly look like they have a coating, particularly when they rotate and are under a bright light. Apparently not a cost cutting exercise but a mass and lubrication consideration. Fascinating!

Sorry if this is old news. Just enthusiastic..
