Eta 2824/36 clone info...

[automatico]

sneed 12:   "When a movement has a Novodiac shock spring and the retaining clip has only 1 notch, it's a clone."

True....almost always. I  have a genuine parts junker 2836 with a fouled up HS so I removed the balance and HS from an 'unknown clone' and installed it on the genuine 2836 balance [censored] (balance c-o-c-k is the proper name but it gets censored) with the three notch Novodiac shock spring and away it went, keeping good time. The only difference was the HS stud was a little bit loose in the fork that retains it so you squeeze the forks together a little. Not much way to tell if this has been done. Clone 'balance complete' sells for around $20 on eBay. This has probably been done to some of the 'genuine swiss Etas' in replicas etc.
