  1. My latest acquisition

    Great steal! Where did you get it from? I got one for 160$ and I believe that was a bargain! 50, 75.. are you nuts?
  2. Tissot PR516 help

    the dimensions are embedded. if you open the .stl files, they are in millimeters.

    P.s. you need: a metric 6, long screw (with 10mm hexagonal head at one end and only a couple of centemeters of thread at the other - the rest, in between, should be smooth) 4 metric 4 screws A spring a metric 6 nut A 35mm diameter piezo Mono shielded cable 25cm long 3.5mm jack (depend8ng on your amp)

    So I played a bit in Solidworks, and this is what I got. A friend of mine helped me with the 3D printing. sup_2.STL mic 2.STL pesa.STL sup_1.STL the editables: mic 2.SLDPRT pesa.SLDPRT sup_1.SLDPRT sup_2.SLDPRT ansamblu2.SLDASM
  6. For the Horotec screwdrivers: do the hexagon hadles loose their color in time?
  7. these are the links. If its not ok to post the links, I appologise and ask (nicely ) the admin to erase them
  8. Hello! I am interested in a stainless steel handle screwdriver set. I oscilate between Bergeon 30081 and Horotec MSA 01.201. Self lubricating vs ballbearing Thank you! Bogdan

    So what was it?
  10. 7750 incabloc stones

    Thank you for your answers! I guess I was a bit lucky too. It was a 50/50 chance to mix them, and if wouldn't have mixed them, I am sure I would have picked wrong in the next 50/50 game of putting them correctly in the mainplate and balance cock. I gues the way to go is to check for different diameters when you dismantle the movement and to make note of the correct way. B
  11. Hello! I am servicing my first 7750 (thank you Mark for the YT videos and Lawson for the Disassembly/Assembly walk-through). The movement is not new - let's say it has an obscure unknown history It appears to be a genuine swiss 7750, but with a lower grade finish (very low...) When putting back the balance stones I noticed that there were two sizes (two pairs, because the cap stones fit the hole jewel settings). I put the smaller stone and hole-jewel on the mainplate and the larger ones on the balance cock. I tried to but the larger setting on the mainplate but it didn't fit quite right. I believe the springs are the same size - its just the stones that differ a bit (aprox 0.1mm) So my question is: did any of you stumbled upon the same issue? Is it normal for a 7750 to have two different stone sizes? Thank you! Bogdan
  12. I can't figure this one out

    what screw issue?
  13. Bergeon 30209 Or Make the same scenario using a reverso staking tool using two screw-removing stakes. ...just thinking out loud The other option would be to disolve the screw using Alum.
  14. Tissot Seastar balance spring

    I would take off the HS from the balance. It would be much easier to manipulate the HS this way. Just make a note of the collet orientation on the balance wheel
  15. re-seating an incabloc spring

    use rodico to hold the spring and a fine tweezer to manipulate it into position. The last photo in the previous photo is the key.
