Don't know what this is. Has a plaque where it says it is Made by frontier watch tool laboratory. Says frt trademark made in Japan On another sticker.

The base is 3.5x6 in roughly, cast iron with hammered paint finish. Very solidly made.

Can anyone tell me what it is? Photos in link.

Tell you what the mechanics kinds remind me of......i dont think it is...but a ring stretcher.

Neverenoughwatches, I would say the same thing a ring stretcher

Here is the type I had very easy to use but You can't use it on rings with stones all the way round such as eternity rings.

Looking at it compared to OH's picture it does look like an alternative design of a ring stretcher for just bands. Instead of the arm that draws around the frame to turn the rollers the OP's makes use of a hand wheel and as Andy suggested the holding posts for the rollers, probably stack two or three on each post for various ring sizes. Not sure what the adjustable arm is that also carries a roller, unless that is the stretching roller.Screenshot_20241030-092439_SamsungInternet.thumb.jpg.44cf84cfb01af65e8c8a4d9af9be3dd7.jpg

    • Righty ho, I re-serviced the chrono module and got a reasonable result with minimal loss of amplitude when not running the chrono and about 30 degrees loss when running. Great. The problem is now that the chrono (and movement) stops running after about a minute or so, a tap on the watch starts it running again. No issues with the movement running when the chrono is stopped. Going to service it yet again, obviously some residual issues with friction in the chrono module (Very frustrating - I wish there was some way of testing it as I go!) I also seem to have a problem with the cannon pinion where the movement is running continuously (with the chrono stopped) but it's losing significant time / stopping. This is one of those two piece ETA style with a driving wheel pressed over the cannon pinion, obviously arranged for driving the chrono module. I had no issues with this prior to service and just added a small amount of grease between the driving wheel and the centre cannon pinion as the technical guide required. What's the best way of tightening these up? I would like to replace it but I guess this is going to be hard to find as it is dedicated to the DD chrono movement. 
    • He uses the micrometer cap, but he leaves the spring out (you can see that in the video). If you leave the spring in, the spindle will move up as well (as shown by @Knebo).
    • Seems like he doesn't have the micrometer cap  attached to the spindle so he can only push down but cannot pull up? If the cap screws into the spindle I guess you don't need the spring? I only have a "normal" Seitz so I really have no idea. 
    • Do you have a part number for the bearing shim lock tool?
    • Yes in my opinion the 3/4HP is plenty but it’s your decision & yes it does come with speed control but foot operation so my reason for changing to potentiometer was because my leg shakes so it was like me revving the lathe & anyway I prefer to set the speed. I & a few others that I recommended the motor to run a Pultra 10mm lathe so if you have a 6 or 8mm B & L then it will be plenty, if you have seen any of my videos you will have seen that when using a graver I run quite slow without any problems.
