Hello im new to watch collecting and i recently bought a non running 14k curvex. The bracelet is a expandable jb champion that says stainless backs. The tops have small pieces of crocodile set in what tested as 10k, not filled. Is this the original bracelet or was it added later? Ive searched google for anything about the jb champion 10k tops and only found stuff about filled. Also i ran the movement by a compass and it is magnetic. Could demagnetizing actually get this watch running without having to disassemble it?
