Parts compatibility between hunter and open face PW movements?


Recommended Posts

I have a question about the physical differences between an open face pocket watch movement and a hunter style movement. Specifically, I'm wondering how interchangeable parts are between the two (I'm talking only about models of the same brand and model number here). I would assume that manufacturers would attempt to keep wheels and works as compatible (and therefore swappable) as possible, while modifying only plates/bridges? From the pictures I've seen, the only real difference I can spot is where the sub-second hand is located. I've been looking online for this answer, but am coming up with no real information. Has anyone already looked into this that can shed some light on this subject?

Regards.

The simple answer is not many. I could go into detail but it would take ages. When you think about how many different caliber’s there are in watch movements, it’s a small % that are interchangeable.

Pocket watch movements interchangeability would be B/staffs and stems. I am talking here about English P/W. American P/W such as Waltham’s are different, many parts of the movement can be.

 

I hope that answers you question.

Thanks, oldhippy. It does help. I’m also researching as I go, so I’m accumulating knowledge. My specific need to know (regarding movements in hunter configuration vs. open-faced) is influenced by the fact that if components like spring barrels, balances, and train wheels are interchangeable between the two configurations (of the same brand and model, of course), then I can expand my search for parts for the movements that I have acquired. I want to eventually get to a point where I can repair these parts, not just replace; but replacement is the level I’m capable of right now.

I also do not plan on making runners into non-runners for the sake of my particular watches, but finding movements with good balances that still are missing pieces or don't run isn't proving as easy as I was expecting.

Regards.

    • in general this shouldn't be any change. but in general questions like this it be nice to know the specifics of the watch in other words how was it performing before it was cased up and what is it doing now.
    • just as a reminder this watch is a Swatch group product. This will bring up a problem like spare parts and technical information. that I found some links to some information on when I talk about your watch and some of the technical and basically your watch is equivalent to 2834-2 for which I'm attaching the technical sheets. But equivalent does not mean exactly the same you want to do a search on the group for C07 as we discussed this watch before including the technical differences how it's supposed to be regulated and basically because it's watch group there is no parts availability. https://calibercorner.com/eta-caliber-c07-xxx/   https://www.chrono24.com/magazine/eta-movements-from-the-2824-2-to-the-powermatic-80-p_80840/ https://www.watchuseek.com/threads/h-10-movement-details.4636991/ eta CT_2834-2_FDE_481857_15.pdf
    • people be honest.... Swatch is evil for the watchmakers and repairers, BUT not everything in watches from Switzerland is from the Swatch-Group. As far as i know, Selitta got sacked by Swatch as a Movement-Assembler for them and they started to produce Movements in their own Name with slight Modifications. As far as i know, they sell Parts to the Market for their Movements. In most cases, if a ETA-Movement fails, it is a valid Option to replace it with a Selitta Movement, which i consider the Solution for this Mess with the Swatch-Group...... I have no Connection to anybody at Selitta, but being a Swiss-Guy, i still like to have Swiss-Made Watches, but not from the Swatch-Group.   ok ? regards, Ernst
    • Just one more greedy act by Swatch. They started a number of years ago here in the US..cutting off supplies to watchmakers that could build complications that many Swatch houses couldn't even touch. Old school masters who had gone through some of the most prestigious houses in the world. Otto Frei has some statements on their page about it. I tell all my customers to avoid new Swiss watches like the plague,..unless they just want an older one in their collection that still has some parts out on the market, or they have really deep pockets and don't mind waiting months and paying through the nose to get it back. Plenty of others to choose from..IE Seiko,..or other non-swiss brands Even a number of Chinese brands are catching up with the Swiss,..and I think that in time, their actions will be their downfall
    • Yes. If that's not what you are experiencing...start looking for something rubbing. A 1st guess is that one of the hands is rubbing against the hole in the center of the dial. Especially if you now have lower amplitude in face up/ face down positions.
