After doing the two swiss cylinder movements it taught me a very important lesson about swapping parts. You dont always realise the consequences straight away. I swapped an endstone on the balance with its small round plate and lever. I never noticed on the lever that the end was shorter and the boot was not quite deep enough. This resulted in squashing the hairspring up on one side. Could i then find the original lever? In a word no! My mentor teaches me to repair what i have, as soon as you start changing things you are moving the watch further away from its original running condition and this can cause more problems than you think you are solving. Obviously things like jewels and mainsprings can be changed but they must be the correct dimensions.
Looking forward to fishing with you one day
