To be honest you won't find a balance wheel easily. It is not a watch to learn maintenance on unfortunately. I own a 26.5 SOB movement and I am lucky it is 100% in working order. I recently thought it had a broken balance staff which do still come up for sale - finding a whole wheel for under $200 will be hard. Expect to pay $75 if you do find one. There are some videos for straightening hair springs. unless you can reshape it with some oilers and tweezers under a microscope I would give up. You may find another hairspring from a similar watch somewhere. If you get really stuck, I have a similar caliber omega pocket watch balance which you could have for the price of postage (Say $10USD to wherever you are) - but dont know if its drastically different.

I would check the escape wheel. Check it's pivots for damage and if they are straight, check all of the teeth for damage. Also check its jewels. The beat is also a long way out which needs adjusting.,

No, the oil will stay on the side of the oiler until you touch the pivot. If the oil is dripping off the oiler, that's way too much. Here's a couple of YouTube videos from OSUIT that I found very helpful.

Here we go with part 2. Now it's easy to note, that I'm not a professional as the cleaning equipment is only... ehm... semi-professional. Special treatment for the balance and the pallet fork. The equipment for oiling and grease. Inserting the new mainspring. Reassembling the train bridge. Surprise: Much easier than on other watches, the parts fall into correct positions by themselves. Nice. Barrel bridge and ratchet system. The keyless works. Assembling and oiling the Pallet fork. The return of the balance. A drop of oil for the balance and escape wheel stones. Winding up and...it runs! Oops, some adjustment needed. Better. Reassembling the automatic device. Inserting the screws for movement and dial. Time for the cannon pinion and the hour wheel. Bringing back dial and hands (oh, I love those Maxi dials). Back in the case... ...and completed with the automatic device. Some grease for the gasket. Got it. It's called a wrist watch, so it's for the wrist not for the safe.
