I am soon going to have a pocket watch that has a Shunlei Chinese movement. It sounds like a solid enough workhorse type movement for the price point, and I am gettijg the watch for it's sentimental/emotional/geekdom appeal. It's related to the show Doctor Who. Anyway, I am wondering, if down the road a bit, I wanted to have someone put in a new movement, is that generally a doable thing? Maybe put in a new, higher end movement? Thanks for any and all info, help or advice.
