With a crystal wrench you should be able to insert armoured crystals in addition to removing them. I have this Seiko S-14 but I have only removed one crystal so far. Btw that went really smooth. A lot more comfortable than the brass jaw lift. -

I can't say I've found it any better than naptha, why these chemicals specifically for hairsprings ? Just going slightly off topic, yesterday i was sorting out a very poorly balance assembly on a 90 year old AS554. All components of it in bad shape, first to deal with was a rusty hairspring. I did a write up a couple of years ago going through various kitchen items and their chemical make up in order of their aggressive nature on steel. The mildest being citric acid in particular lemon juice, so i thought i would try this first, anything stronger could eat through fragile thin steel very quickly. I used freshly squeezed juice heated on a wax melt heat plate to about 60° and soaked the hs for about 2 hours. Then lightly brushed and rinsed in IPA. The results were very good, the effects of the rust were still obvious but the iron oxide was completely removed. The pictures are the befores. -
Definetly one of these moments:

Hi. If the alternative is not available it is advise able to effect a repair on the faulty coil by the method you choose, it’s either that or the watch is scrap pending finding a working donor.
