ETA 2472, Technos Star Chief - oscillating weight

[Michalzeszen]

Hi there!

Do you guys think I'll have any luck finding this oscillating weight? I bought a second hand, water damaged Technos Star Chief from the 70's, and it came with a different, broken and bent rotor mechanism, as you can see in the pictures:

Not only that, but I can see this is not the original set, because it states "17 jewels" with no reference to Technos, and I know that the original piece would look like the forth picture attached.

I'm nearly setting for this one, but before making the purshase I'd like to hear your opinion.

Another argument to be made is that, since this watch is not entirely worthless, perhaps keeping originality would be nice.

One available here, not too badly priced either

Edit# sorry I see later that you have already this one in mind

How would it bend like that? Maybe an inexperienced tinkerer tried to remove the weight by levering it up... I'd keep an eye out for other problems in this one, especially bent or broken train wheel/balance pivots.

By the way, since we're all learning here, you could have a go at fixing this one! Maybe some careful whacks taps on a staking set (if you have one) would do it. Worst case, you still have a broken rotor. No idea, I've never tried to repair this kind of damage. Of course, get the replacement if you want, but don't pass up on a learning experience.

It seems alright. Actually, I have never worked on a more smooth movement than this one. Take a look:

I'm assuming this watch was used as a donor, for the rotor specifically, and then sold with the bent random rotor as a botched attempt of repair.

I'm quite sure I can make it work with the broken piece, but at the end of the day I know the "17 jewels" imprint will drive me crazy, so I'll order the blank piece to replace it. 

It is a surprisingly expensive watch for a Technos, so let's make the best of it.
