Purchased online and waiting for it to arrive. its a bit rough but im assuming from the pictures its all in workable condition - it will be a nice project to clean up and use,

 

anyone with this item agree with my logic or have i just bought a piece of scrap? - interested in ensuring the precision

 

as usual thanks in advance

Ok guys ive got a bigger one of these that I use for measuring run out etc on brake discs, im a tad confused what the use this has in horology apart from maybe seeing if arbors are bent etc

It's not just a simple DTI, it is a specialised tool developed for horology. Have a look at this video and you will see the what it is capable of. The clip of the instructions is worth pausing, as it clearly shows the types of measurements the tool can be used for.

    • Right now I'm making do with a similar micrometer (the one below is $45 shipped but you can find better deals) and a $20 stand. You do have to be excruciatingly careful measuring jewels, since there's no table, but if you don't have the $500 to throw around, it's a nice option.
    • As  I kid, I'd watch Godzilla stomping over buildings and cars and I'd think to myself: Tokyo is a really dangerous place to live... . Cool watch!!
    • Next one up an AS 554, looks like a bit more to this one. First job is to check thickness, most springs are somewhere between .3 and .4, this one measures .35, that matches in with the .4 spring steel i ordered. So for marking up a permanent marker comes in handy to colour up the steel to be marked later with a scriber once its dry. Bestfit provide the extra bit of info for the jumper spring that is missing.
    • Thanks again, Marc.  Super helpful. I was wondering what the hole was for, and now it makes perfect sense. With your help and the other members here, it looks like I'm good to go with my Seitz tool set. I had to order some replacement pushers, but with those, the set is complete and in good condition. Now, I need to figure out what tool to buy to measure jewels (amongst other watch-related parts). I had my eye on the JKA Feintaster micrometers, but people get crazy bidding on them for $400-600 USD. I was thinking of just a regular digital micrometer (Mitutoyo). Thoughts?  Mahalo. Frank      
    • Yep, that's exactly how it should fit. The reamer shank is tapered and the socket in the spindle is also tapered so that the one centers in the other and is gripped tightly. If there is any wobble when the reamer is seated as far it will go then there is a problem. The cross hole in the spindle is to allow you the push the reamer back out again. If the reamer seated much deeper then it would limit the access for pushing it back out again. Here is one of mine for comparison.
