  1. This is the tutorial from Nicholas Hacko: http://www.clockmaker.com.au/rolex/rolex_case_polishing.html "Step 4: More of the same. Medium: 3M Film sheet polishing (plastic) grade 60 microns and 10 microns (2-3 minutes each). Available from jewellery suppliers only. On touch 3M film eels like ordinarily plastic sheet, definitely not your ordinarily sand paper :-)" Also, I still have no idea what is Silicon Carbide 800/2400. It is probably P2400 but that 800 stands for?
  2. Hello I just got my shipment from Cousins and I am just confused with grades. I will use different sand papers and films to polish watch cases and bracelets. So, I have this: P800 sand paper Matador Siliciumcarbid P1500 sand paper Matador Siliciumcarbid 60 microns polishing film (3M Microfinishing Film Aluminum Oxide 5 Mil 272L) 9 microns polishing film (3M 3M Microfinishing Film 268L) Dialux Green with Dremel The polishing film that I mentioned above (60 microns) is way too coarse and feel like P200 (that rough). Did I ordered something wrong? Also, I have one old
  3. Hello After few years I decided to get back to this old alarm clock, which lays disassembled in parts in my drawer. I work with wrist watches and although these clocks are bigger, I have no experience with principles how they actually work. Any sources where I can take a look how to assemble this clock again? Perhaps some manuals for other similar clocks which could be useful? Thanks.
  4. Thanks. This is the movement I am looking for: https://17jewels.info/movements/t/timex/timex-m23/ P.S I hate this movement too.
  5. Hello I got back in the hobby and gave an old Timex lady watch another change. Well, I learned that these movements are not meant to be serviced at all, since assembling them again is almost impossible. Anyway, anybody knows where I could buy a working M23 movement and just replace it in the old case? I don't really need to, buy I would like to have it at least working watch in the drawer. Thanks.
  6. Question for people who work with Seikos: series 6 work fine with left handed nr. 7 bergeon arbors. I read somewhere series 7 use left handed nr. 6 arbor. So I am little bit confused since I am not sure should I buy left handed nr. 6 or nr. 7 arbor? Thanks.
  7. Thanks but I would like to try to service them anyways and and start building set. The main question is if I buy left hand arbor and put it in right hand winder and into right hand handle, would I be able to wound left direction mainsprings (for example, series 6 Seiko).
  8. Hello After trying to find a decent and reasonably priced mainspring winding set (and failing to do so, since the arbors of the set I have are basically too thick) I guess I will have to go for Bergeon. Since I am on budget, I was thinking buying only I need for now. If I understand correctly, Seiko 5 has several movements (6 series, 7 series, 7s26 etc.) and they wind in both right and left direction (clockwise and counterclockwise). So, my idea is to buy the following: Right Hand Mainspring Winder Handle - https://www.cousinsuk.com/product/watch-bergeon-handles-for-winders
  9. This is another one I found, looks like Bergeon thing, but again I am not sure if it is suitable for wristwatches:
  10. Hello I would like to learn to polish watch cases and bring them back to life. Would something like Dremel 3000 do the job? I guess the number of RPM is important to be able to do the final polish properly. I prefer to do everything I can by hand and the last part to finish with a rotational tool. Thanks.
  11. Exactly, my goal would be to be able to finance my hobby by selling repaired and cleaned working watches. I guess I need to stick to some model in order to have enough spare parts and proficiency to actually fix them properly. The model that comes to my mind is Seiko 5, since this is the watch I worked with many times and it is widely available on Ebay here in Germany. Any other option on cheap watches worth working on?
  12. Hello everyone, this is probably not a question, but more of a call for a discussion. Watches and clocks were always interesting to me and once I discovered people who do watchmaking as a hobby, I decided to give it a try. Mostly fascinated because of the precision of mechanical parts and skill required not only to put parts correctly in order to make a watch tick - but to understand how the things actually work. Great thing is that you don't need much space for the equipment (as least basic tools) and there are also plenty of books available to learn. Not to mention great forum such
  13. I would always recommend buying some old high quality tweezers instead of new ones of less quality. Tweezers are extension of your hands, and this is job done with hands. Just keep attention that the tweezers are in fair condition, I bought used Dumont 2, 3, 4 and 5 as a pack and got them cheaper. For the beginning, 3 and 5 should do the job pretty well though.
  14. I will skip it then. What about this one? I guess the arbors are still too big.
  15. As I started with this hobby, I picked old women's wristwatches and practices on them. The reason was that they were really cheap and some of them worked for a few seconds and stopped again (sometimes sign they haven't been cleaned for a while). The drawback is that these are really small movements and you need to be very clean and patient in order to put them back. I destroyed few of them, but once I started with men's wristwatches it was a lot easier since the movements are bigger. In other words, once you master small movements, it will be easier to move on bigger ones. But maybe
