  1. Hello. I recently got interested in watch polishing. Since I usually work with vintage watches, I would like to learn how to polish a acryl crystal. I tried polishing acryls by hand with sand paper and Polywatch but it owed me a quite amount of time and effort. Also I want to move on to case polishing as well. I looked up the internet to find a full guide on watch polishing but I was not lucky enough to find the one that seems like a "complete guide" on polshing. Would there be a source from which a hobbyist can train oneself to become a pro in watch polishing? Any advice would be grateful! Thank you and I always appreciate your kindness.
  2. Hello dear watchmakers. I am working on a Unitas 6360 movement, Swiss made from 60s. I definitely have to get new hairspring for this watch and I am searching the web to get the best deal.. On ebay, I found hairsprings for UT 6475 , UT 6310 and UT630. I wonder if these would work. Also, is it OK to install screwed balance instead of non-screwed?? Any advice would be grateful.. Thank you!
  3. Hello. I am working on a vtg. Citizen cal.7520 automatic movement. I have put the watch on the timegrapher The graph looks OK but the beat error shows 9.9ms. I presumed that beat error should be around 1.0~2.0 given the shape of the graph. Is the beat error actually bad or the timegrapher is wrong?? Thank you!
  4. Hello. I am about to work on a Omega ladies automatic watch. I found out that the axis of the rotor is out of place and shakes up and down. What could be done in this situation? Thanks!
  5. Here are the photos of the mainspring and the hook parts of two arbors I have. If I had no choice but to use what I have now, which arbor would work better??
  6. Hello. I am working on Seiko 6309 automatic movement. The movement was quite dirty ao I cleaned up every parts of the watch. What is giving me a headache is that the mainspring and arbor do not go along well inside the barrel. I install them in the barrel then with pin vice, I hold one end of the arbor and try to wind the mainspring. When winding the mainspring this way, it works fine without the the arbor slipping away from the mainspirng. Then the barrel is mounted on the plate and rachet wheel is installed on the arbor with screw. This time I try winding the mainspring by turning the rachet wheel screw with a screw driver. Problem occurs here. As the spring is wound, unpleasant slipping sound is heard from the barrel. Then I take out the barrel and open the lid only to find that the arbor has escaped from the inner coil of the spring. What could be done in this case?? Thank you! I don't have any photo but I will take some shot if it is necessary
  7. I see! I will try removing the caseback I appreciate your help.

  12. Hello watchmakers. I am considering taking BHI dlc course and I would like to get some advice from those who have had taken the course or know someone who has. Here are some questions I want to ask. 1. What kind of tools would I need for Technician Grade and Intermediate Grade?? 2.

I always appreciate your generous help.
  13. Hello I had a chance to acquire to two watch movement+dial sets which are from JLC and AP However, I am having trouble finding cases to fit these. Could anyone help me find cases that would fit these movements? Non genuine cases are OK.
  14. Hello! I am working on a vintage watch and the crown of the watch is fitted with a hidden type gasket which is in terrible condition and needs to be replaced. However, I found it difficult to pull the gasket out with my tweezers or tooth pick. Could anyone recommend an easier way to remove this kind of gasket from the crown?? I forgot to take a photo of the crown so I attached a similar example I found on the web.
  15. Well thank you all for advice!! I managed to turn the gear to put it back to correct position and the disc now shows the day correctly. Thank you for your help!
