    Watch material and manufacturing choices (case coating, mineral vs. sapphire case back etc.)

    Hi guys!

    As some of you may know (I've received great help after my previous thread) I'm in the process of designing and manufacturing a watch. As Chinese New Year is coming to and end, I'll soon be ordering prototypes. Before doing so, there are a couple of questions I'd like to know whether anyone here has any experience with previously:

    - Case coating/ plating: What's really the difference between coating techniques, e.g. PVD vs. IPG vs. DLC, in terms of cost, quality, durability?
    - Mineral vs. sapphire glass on the case back: what are the risks of using mineral glass instead of sapphire glass for the case back? I mean, I guess the risk for scratches is less - at what kind of price level would you expect sapphire on the case back?
    - Screw vs. "common" crown: Unless you're going for a high water resistance, is there any point in having a screw-down crown? Doesn't that just make winding the watch more cumbersome?
    - "Movement holder": First of all - what is this? :) Second of all, what are the advantages and disadvantages of having a plastic vs. copper movement holder (except for price and weight)?

    Very grateful for any help on the above topics! :)

    Regards,

    Jonas
