  1. Absolutely nothing goes in there.
  2. Do you have a timegrapher or equivalent application? That will tell you more than just the rate.
  3. He specializes in mov.t parts. Beside, Seiko never sold bezel inserts separately.
  4. I hear this complain a lot, but honestly I find these spring quite easy to deal with. For the balance ones there is two methods, first the "tweezers only" one where you keep a thin finger of rodico over it and use the tweezers to put it in place. This methods require moderate manual skills, so I decided to document the other, which is even easier. File a pegwood to the shape below. If you don't have pegwood, use a toothpick, brochette stick, or anything like that. The outer diameter must just go inside the jewel setting, then carve the inside with a 1mm drill bit. The rest is intuitive. Note how the spring is very off-center before applying the stick, but the soft wood easily takes care of that. And for the small ones in the train t's even simpler, don't bother removing them, wash the plate, oil the related pivots, and enjoy the good results. I don't really think you can find a better finished mov.t at this price point, except possibly on some Seagull. I don't see anything wrong or ugly in the pressed posts.
  5. Not really, considering that there is no anti-shock in your mov.t, I suspect that when these became common, many watch repairers became.. upset.
  6. As asked and answered before already: I do lubricate the stones of the pallet fork with with a very small amount of 9010, which is what Seiko recommends, they call it "Moebius A". Attached service sheet. 6R15B.pdf
  7. But the OP here knows that already: I know my great great grandfather (Marks Jacobs) owned a jewellers store He wants to know instead if he worked firs-hand on watches or not. No census or genealogy research can reveal that.
  8. Not sure what do you mean by that. 6R15 based Seiko cost easily $500 and their owners usually take good care of them. Actually the Seiko Diashock system is one of the best ever made, with possibly millions of units produced. Easy to work with and highly effective. Finishing is simple but very nice. Cotes de Tokio on the rotor, beveled balance cock, and few more details. Made in Japan. The 6R15 is primarily a mov.t for JDM watches.
  9. In the decades before the passing of your great-grandfather it was common that watch case and movement were assembled by the jeweler, according to customer's taste and budget. Surely he was doing that in his shop, which in my book qualifies someone as a watchmaker. Perhaps his offspring were more qualified than him, but that's cherry picking, your heritage is there and proved.
  10. That is a "Watchuseek Chinese Mechanical Watch Forum Moonphase limited edition", based on a Seagull ST25 mov.t. It is not a cheap watch. It could be possible to repair it even without access to spare parts, but once again, if you want to give your nice watch a chance to survive, please do not try yourself.
  11. Have you worked on a watch movement before? The general approach is to take it apart to see where the problem lies. If you care about this watch it would be better that you give the job to a professional instead of trying yourself.
  12. Yes, as in picture. As mentioned: "remove balance jewels, balance and pallet fork. Applied 9010 to the (related) stones". Nothing else.
  13. Which probably is made for objects much larger than a 0.2mm crevice on a watch case. I'm very happy how the repair turned out, and so is the new owner.
  14. My thought is, remove money from the equation first. Judge things for what they are, their objective physical characteristics. And then you will be able to judge what is overpriced and what is cheap, with all the large lot in between. Works for tools, for watches, and most other material objects.
