Rolex Day-Date – Cal. 1556


  1. Movement very easy to do. Good idee to change the mainspring.

    • Agreed.
      But, there were some problems with this movement though. Someone worked on it in the past, and didn’t show it enough love.
      The center wheel and canon pinion needed to be changed.
      I always prefer to change the mainspring when I’m doing a full service of a movement. It just gives watch repairers a better start.
