Very interesting. Thanks for sharing
My MG is not so loud. I can’t hear the best unless I put my ear close to the watch. On the other hand, my gronefeld remontoire is the loudest I have heard. I can hear it miles away. 🤣
Unique Hamatic automatic movement from Moritz Grossman
Inspired by vintage pocket watch movement ...
Finally, we get to see the back of your M. Grossmann Hamatic
...many thanks for the fabulous view of a truly unique movement!
For the Hamatic, "like" is a slight understatement
Half a year ago I tried snagging one at auction that another purist was offloading, but the numbers quickly zoomed way beyond my limit (good for him, sad for me!)
I remembered that auction in HK…
Indeed that esteemed purist offloaded quite many of the superb pieces, each of which is a grail of many of us, unclear as to why but I guessed it must be for something bigger.
indeed, at least 20 or 24 pieces
...and those are just the ones i could identify. something bigger indeed, am guessing not a timepiece.
Beautiful! A feast for the eyes. :-)
Thank you for sharing this rare piece of mechanical art (and a very efficient winding mechanism to boot).
Does anyone know if Grossmann is the only brand that puts screw-posts behind the pallet jewels?
They're very visible in your picture. I like how they amplify the running sound of Grossmann wristwatches -- you can hear the watch tick-tick-ticking halfway across a quiet room
In the Zeitwerk the posts are banking pins playing a functional role, aren't they? [Apologies, I sould've been clearer with my inquiry]
On the other hand, with MG the posts seem to be present in all movements, with the stated purpose of deliberately emphasizing the acoustics of the calibers as they run. (I vaguely recall someone at MG describing it as the "breathing sound" of the watch, a...

I've not yet had the pleasure of seeing/holding a Gronefeld watch in the metal
If & when I finally do, I'll make sure to do a "sound check" -- thanks for the tip
Love this movement!
This is definitely on my "for later purchase consideration" list. Curious if you have found it any different than a regular, rotor wound automatic? Any difference in the way it feels or the "ease" of winding?
Very beautiful movement on this one.
The hammer rotor here does not move as easily as the regular rotor. So the winding efficiency is not as good. The swing motion is great to look at though.
