I thought I could suggest a small but nice thread showing Eterna cal. 852 watches. The occasion is the completion of a repair of one of my current favorites, a 36.5 mm steel watch with the 852S - still without shock protection. The balance staff was broken, as well as the bearing jewel under the balance. In addition, the mainspring was weak. Now everything is like new and I am very happy.

Best regards - HU

Fabulous watch, congratulations. I thought that the screwed in element seen under the regulator arm was part of some kind of shock protection on these great movements. No?

Correct. I should have written that the watch has an "early" shock protection. My point was to distinguish between the "early" shock protection (which I can't really imagine springing the baring jewels in such a way that the balance staff is halfway secured - especially since a really large balance is mounted) and the later shock protection concepts, where you can recognize from above that a spring is active.

Thanks Tony and of course the same for you!

Thanks also to DD12 who helped me a lot with this watch!

After a restless night with dreams of baring jewels, feathers and staffs, I spoke with my watchmaker on the phone. On my question whether he finds that the watch has a shock protection, he answered spontaneously with "No". On my objection that it must be a "kind" of shock protection (or intended as such) he said that then the steel plate on the balance cock (with the two screws) should be much thinner or softer - e.g. made of brass. But it looked as if someone had thought that construction at least in the direction of shock protection...

Interesting information about the stiffness of the steel plate, thank you.

P.S.:
On the main plate of the watch shown at the top, there`s a "L" in addition to "852S". I had not noticed that before.

Here's another 852S (similar to the one from the beginning of the thread, maybe a year or two older) with 37mm case in pretty good condition.

A recent addition, Cal 852S, 37mm, the gilt dial is a little tired but the seconds hand is irresistible, to me anyway. Fixed strap bars and a gold bezel on a s/s case.
