    He "only" made the case and buckle, right? I mean he didn't make the movement, hands and dial, did he?

    According to the caption, he made everything except the screws. One presumes that includes the entire movement, as well. Although, I tend to wonder if he made the jewels.

    Did he make it for Shreve Crump & Low of Boston, which appears to be what is on the dial.

    I would have to assume that if he’s referring to the case and buckle he started with castings and finished them to dimension. They could be billet but I don’t think one would want to start with a block of 18k rose gold and machine out those parts.

    Gold can cast detail surprisingly well. For the case & chassis, best would be to machine a block of wax. Shrink rate for usual 18K alloys is less than 2.5%; still enough to have to take into consideration when machining the wax. Then machining is really just to true up the work, with much less waste.
    Gold is "sticky" for machining and it readily binds with steel, so cutting tools need to be adequately lubricated. I use bee's wax for blades and lathe work.
    With gold and silver, there is a huge difference in the temper extremes. Annealed gold & silver is so soft that it's nearly useless for durability and for machining. So my GUESS is that the maker had the case cast and then heat treated by the caster. I know from experience that the difference between machining cast annealed gold and work hardened gold is like night & day.

    I have machined parts from both 14k and 18k soft yellow gold in the past. Some parts were cast and a few simple parts from solid bar stock. However, I was fortunate enough to have diamond tooling. When speeds and feeds are correct the diamond tooling cuts clean and leaves a finish that requires little additional polishing. They would disassemble the lathe for a good cleaning once a year and send the wooden work top out to be burnt.
    There really isn't enough detail in the description on the Taig site for us to know what the guy actually did.
    Regards,
    Jeff

    Regardless what may have been turned or cast, I am awestruck when I see this level of work by any individual.

    Good Day to all,

    I too have turned gold and silver in my lathe. Two examples are shown on the images below. The first one is an IWC in a new 18ct. yellow gold case designed by an artist friend.

    My friend had cast a large ring of gold, which I used to turn the case from. Turning it was a major pain but it was well worth the effort. The final product was case of 2-1/2 oz of gold, without the movement. Case was additionally decorated with few diamonds just for a kick.

    Unfortunately, this watch got stolen several years ago. I did that one over ten years ago. Since that time I have done other cases as well and have learned what one should not and what one could do with precious metals.

    The second one was a chrono, not a bit less of problem.

    As with all other things in life it is live and learn.

    Cheers

    Dushan

    It is a beautiful job, but I'm sure it's just the case that has been made. The movement looks like a commercial one, and there's no way you could do things like cutting wheels of that size on a Taig.

    I'm no way decrying the work, though.

    Curiously, it was done in UK; on the forum here, I see talk of "making a clock" whereas the threads are really "making a clock case" as we in UK would call it.

    i think the person did make the movement..the movement to me looks in no way like something mass produced...the movement doesn't look like anything i had ever see...the movement i think was made.. the taig, i don't have one ..along with a sherline can make watch parts...from what i i have been reading both machines seem capable of making alot..like jerry says its the techinque and the way you do which is different...also i think if the person was able to make the movement i would think he would be capable of signing the movement... on other sites that talk about both lathes (the sherline and the tiag) if they show how someon made just the case they say how it is just the case that has been made..

    The watch is nice but I'm thinking of the top project. It looks like you could thread the prop side of the engine to fit an 8mm headstock and extend the shaft through. You could turn between centers powered from the head stock. :)
