I had thought about doing that. Is there a concern that if I can't get the crown off that the water from rust remover and penetrating oil might get trapped within the crown/stem assembly?

Hi, Does anyone know if there is any kind of dimensional reference for the Seiko jewels used in their movements? Specifically I would like to know the dimensions of Seiko part 011307 that I am not able to source. The jewel is found in the 27 jewel 4006 movement as well as some other obscure Seiko movements. -

Finally I have the watch running at approximately -5 SPY off wrist approx 15 degrees and approximately +5 SPY on wrist. I did try adjusting it over a larger temperature range of +5 degrees up to on wrist temperature without success. I could adjust well at both 5 degrees and wrist temperature but I then found that there was a significant loss of approx 20 SPY at mid temperature of around 20 degrees. -

I would soak in rust remover, then penetrating oil. Source a tube just larger than the gear, and fill with glue from a glue gun. I know the glue hasn't got much shear strength but over the surface area it might work. Worst case scenario, the glue shears, not the gear. -
I have it stripped down to just the case now, those were just photos from the disassembly. I was trying to turn the crown while holding the gear, I think I'll give your suggestion a try and trying turning the gear instead. One thought I had was that if I had enough 3D modelling skill (I don't), I could 3D print a jig that would fit over the gear and allow me to turn it that way without risking damaging the teeth. I'm really hesitant to use too much force on the gear as if it breaks, the watch would just have to go in a drawer or on ebay for parts as I would never be able to find a replacement part.
