Greetings, I am thinking of selling my Modular 45 with a Calibre 16 mechanical module. The connected watch is used and I have a white band and extra new/unused black band. The Calibre 16 module is brand new and has never been used. I also purchased an additional charging puck and later on a stand. All of this is in its original boxes. What do you think I should ask? Thanks, G.
