There is a valid point to not servicing 2824/2836 movements. But here is why I do it. It is nice to have them as regulated as possible. But more importantly everything is cleaned, dusted and properly sealed against the elements. And other than relume, if appropriate, all the other things are included when it is serviced. IMHO, any watch that you are paying more than $200 deserves a service. The lower cost ones I do nothing. When they die, they die.
