Should I attempt to correct the stud curve first? 

This question implies that you think you're going to have to bend the hairspring in several places other than near the stud?

One of the interesting things in watch repair is everyone has different techniques. For me from the limited pictures it looks like a problem around the stud and personally I just fixed the problem everything else should be fine. But I'm looking at a couple of photographs with limited view versus holding the watch in my hand where I might see something entirely different.

Then learning as you go is the typical way all watchmakers learn but before practicing on live watches you really should practice on separate hairsprings balance complete and disposable watch. Hairspring manipulation isn't something you learn fast. A really helpful reference for learning hairsprings is a book by Fried, Henry B: “Bench practices for watch and clockmakers” with a rather sizable section on fixing hairsprings. Another reference can be found at the link below the book Joseph School of Watch Making Personally I download the entire book it's really a wonderful reference but Specifically right now Unit 6 - Hairspring Truing.

Then I have a couple a images out of Henry's book that you might find helpful. Notice both hairsprings are centered and yes there is no balance wheel there. But notice the terminal curve's there different. You have to be careful with the videos and other sources that are showing very specific ways that terminal curve's are formed because that may not be the way your hairspring terminal curve is formed. The balance complete image that I got shows a very gradual curve similar to figure 90 below.

Thanks @JohnR725

After careful studying of the spring in situ, every alteration I made just didn't address the issue and I began creating new issues. I have opted to obtain a balance complete which should hopefully be the end of that problem. although wile waiting for my new tweezers to arrive, I though to fully assemble the rest of the movement and ran into another snag. The oscillating weight in fouling on the setting lever screw when it rotates... I don't recall this occurring when i first obtained the piece, but I cannot see a way around the issue...

    • 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.
