    CNC Making a Wrist Watches Housing..

    Hi guys.. since I took a break from RC modelling, the lifestyle ideas grow ...
    Noo not Apple but other luxury things like watches and jewelry.
    Since my studies in Black Forest I hooked a heart on mechanical wrist watches ... far from beein able to effort a Breitling or other pilots chronograph
    it was creeping into my mind - "...but you have a CNC"!!

    Ok, the short track .. since that time I have the dream to setup my own mechanical wrist watch unsing an ETA brand 7750 movement also assembled in some newer Hanhart or the "cheaper" Rolex lines . You have to know that that movement in the basic appearance is not that expensive, but as soon as the luxury guys get their fingers in ... they blue the screws engrave or pearl the bridges and cover that parts with Gold so the price raises up to several thousands of Euro ... for me the standard configuration is good enough and should I be able to join a workshop or a clockmakers hobbyists class one day, I think I can do what I did not miss so far ( then) ... But now ...

    let the pics tell ...

    some data :

    The Material is 1.4112 - for the US Guys it is stainles knife steel AISI 440B
    Movement ETA 7750 "Valjoux " TOP Grade
    Wrist Band : either a Kaufmann band ( I like the butterfly mechanism to close it) or a

    Do you have any drawings on the mechanicals of the watch and how it works? This is something I'd be interested in making...

    @Dstryr: About the movement that is also something I thought of making ... but the tools especially the small gear cutting mills are that expensive

    If you visit the ETA.ch site and there got o the support center - there is much detaied description ... of course without scale drawings ... but illustration and how it works (ut there are stil some parts a "normal guy" is not able to do ... and even the Swiss clock industry is not able to effort that tools for everyone ... and buying their parts from ETA.

    But a bigger "stone age clock" shoould not be a problem at all!!!

    Hi Harpye,

    Might I ask what kind of CNC gear you used to make your watch case?

    I know it's an old thread but what a machining job, and the movements appear to be reasonably priced on Ebay, although the clones are a third the cost, but I'm sure not up to anywhere near the quality!

    cheers, Ian

    Wow, that's some really incredible work!

    That looks like you made your own tourbillon?

    How did you go with the machining the parts, and getting it precise and smooth enough for integration with the movement? And I assume you've seen Clickspring's videos on bluing screws? He made some nifty trays for that purpose to get nicely repeatable results.

    Lastly, more pics please! I loooove watch porn like this!

    cheers, Ian

    Hi Ian!

    The tourbillon is still in progress ... there are missing several gears but at the moment the regular business takes too much time to find the patience to engage into this without making mistakes!

    I think I'll attach some more simple parts....

    BTW this was the last attempt of an own tourbillon movement which was not successful due to the necessary parts and the availability....

    This is just the hands gear ... solved in a bit unusual way...

    Just amazing work!

    There's something about guilloche work that I find really mesmerising, I could never tire looking at rose engine (or CNC in this case) work for ages, it's so beautiful.

    And making your own tourbillon, that's just incredible to tackle something that complex. Looking forward to more pics!

    I know it's horses for courses and everyone's tastes are different, but I've never understood the attraction of digital or smart watches over analog watches.

    cheers, Ian

    If you really want to be gob smacked look up Abraham Breguet, considered the greatest horologist ever, who invented the tourbillon

    And to see some more absolute jaw dropping eye candy, look up George Daniels, universally considered the greatest watchmaker in modern history, who invented the coaxial escapement completely revolutionising modern watch making, and helping to re-ignite the entire watch market.

    It's all extremely fascinating stuff, and knowing what's involved I have the utmost respect for people making watches, and tackling making a tourbillon, wow!
