Untias st3600. Balance jewel spring

I've been searching without success. Can anybody help?

I was practicing my course work on the Unitas 3600, trying to clean the jewel in the balance complete. I removed the jewel and touched the spring. It went 'ping' and no amount of searching has met with success. I've looked long and hard for replacement springs, even buying a set of 25 assorted. No spring suitable for the ST3600. Not a happy bunny. Apart from buying a complete replacement movement just for the spring, can anyone point me in the right direction to obtain the replacement.

Regards

Ross

Unfortunately Ross this is very common, if you search the forums for “st 3600” you will get several like this.

 

I haven’t seen anything anywhere of spares available for these movements at all.

Had it since Dec 2021. First thing I bought it for the course. Rebuilt twice for practice.

I've heard it before that these eta clones are impossible to get individual parts for. Not particularly well made, Chinese products are never quite there with quality. Sub standard materials along with poor manufacturing produces something thats isn't going to last like genuine Eta. If you want to stick with new then maybe an inbetween like Sellita, but that is going to run you much higher in price. Apparently their spares are accessible to us mere mortals.

Feel your pain..I never did find a replacement spring. I even ordered a new spring from CousinsUK at some expense for the ETA movement thinking it would fit (it didn’t). So the ST3600 sits in the drawer…..

Ross, had that happen to me and I had to buy a whole new movement.

Unitas 3600, or Seagull 3600?

The Unitas 3600 is Swiss from the ‘60’s.  

The Seagull 3600, I believe, is a Chinese clone of the Unitas 6497.

 

Sorry. Unitas 6300 is the Swiss one from the sixties.
