I've recently become interested in watch design and possibly production further on down the road.
Long story short, I'm currently migrating to Australia and awaiting Visa approval so I'm filling my time with learning CAD/CAM and designing a watch being as I am not allowed to work.
I've managed to design what I think is a pretty sweet dive watch, fudging my way through by collecting bits and pieces of info on dimensions and tolerances and such, but there's one area of the construction I'm not too satisfied with. ( I have no watches i'm willing to dismantle in order to visually verify the mechanics so it's a lot of guess work)
My question is this:
Does anyone here know where I might be able to view some detailed drawings with exploded views and dimensions of various styles of watches, primarily dive watches? I've had a go at searching the web, but have only found very rudimentary drawings or cross sections which don't quite provide adequate knowledge on or illustrate the workings of rotating bezels and water-tight fixing of crystals within them.
I'm fairly knowledgeable on the majority of a watch's design, but I am perplexed by the rotating bezel system and crystal attachment for a highly water resistant dive watch with a unidirectional ratcheting bezel. I know a little of the mechanics; crystal fixing ring, click spring, gaskets, etc. as per this drawing: http://www.thewatchsite.com/index.php?topic=283.0 however, I just can seem to grasp the assembly concepts and principles.
Perhaps I'm making it more complex than it really is.
Furthermore, any exploded drawings of water-tight crown assemblies would be quite useful. Although I think I've got a fairly good understanding of that area, any precise drawings would only serve to help.
As I said earlier, I have but one watch with a rotating bezel and I'm not too keen on dismantling it without proper tools or know how, even though I realise that would be the best way to learn about the workings of a watch.
Thanks for reading, and thanks for any help.
