Im working on an Elgin Grade 336 Model 5 pocketwatch... On a whim, I bought a digital magnifier on Temu that seems to work pretty good. Better than my loupe, and better than the magnifying headset I got at HF.

Anyway, upon magnifying the balance to check for any damage, I can now see that the impulse jewel has a flat face. I thought it was round. Is the jewel ok, or has it split?
