Henri Perregaux movement?

[sazabi2001]

Just got this pocket watch movement. The finish looks really nice, Most of the parts are coded (with 2 dots or 2 cuts). Currently the best movement I have, as I don't normally buy expensive watches.

Marking seems to be H&R or H&P, possibly a Henri Perregaux from around 1900?

It has a Maltese cross on the main spring barrel… I’m not sure exactly how it works but it’s suppose to produce a more even main spring tension. That’s very cool to see

The Maltese cross is sadly often missing in many old watches, because people were not aware of the function, it prevents someone from winding the movement too hard and will slip like a clutch if you try.

It's a really nice movement! I have always been impressed by the amount of work done to something most people will never see.

Yes, it does seem like that. But the whole mechanism seems only held by a small pin, I doubt that the pin will brake before the clutch started slipping.

Also, the mainspring barrel seems only attached / to / hanging from the bridge, the main plane has a big hole for the barrel but not touching it, kind of new to me.

Many thanks for the help... I never heard of this brand though, seems like it produced only this type of movement.

Yes, this one is nicer inside than the outside. Originally I just planed to buy the cheapest wolf-teeth movement on eBay, and I'm very happy with what I paid for.

This brings me to the next question: Are most wolf-teeth movements at this level, or even better?

My experience is that only the best movements were made with wolf teeth, I have at least not seen any low grade movements with that design.

That's not exactly correct. What the Maltese cross (or stopworks) really does is try to use just the "best" part of the mainspring to run the watch. If you'll notice there are several edges with circular cutouts and one that is flat. The circular ones can get by the guard finger. The flat one cannot. So in practice you would assemble the watch and figure out the midpoint of the mainspring by counting how many turns to fully wound and then letting it back down. Then you would figure out how many turns there are with the Maltese cross installed. Split the difference for the maximum use of the "midpoint" of the mainspring. So once it's all assembled you cannot break the mainspring by winding it too tight since the stopworks prevents you from ever winding that far and the mainspring also never runs completely down because again the stopworks limits it's travel.

It will not slip like a clutch, once wound it will just stop dead and prevent any further winding.
