  1. I would just like to share my situation regarding 7s26 movement. For more than 10 years I've got a SKX007J, with eng/arabic day wheel and a 7s26B movement. Perfect watch, but with one big disadvantage : the movement accuracy. Yes, more or less it was still running within specifications (-20 to +40s/day) but I would expect at least better consistency. I expect that during normal wear in the office (with no stress) the watch would every day advance/loose for more or less same ammount. But my watch at first run one or two days 30s fast, then the next day was all of a sudden 20s slo
  2. Hello, thanks for both answers. I have already tried using another balance cock jewel with another jewel spring but the problem remains the same. If I press on the jewel, the balance wheel stops, so I suppose it should be ok. I still need to inspect the hairspring rubbing, but in my opinion I would already see this anomaly on the timegrapher as "wired " lines? In my case both timegrapher lines remain perfect (without "snow") and with minimum or no beat error...
  3. Hello, I'm trying to service a non working 7s26C movement. I have dissasembled, cleaned and oiled it. I have also changed the complete balance. The old one was damaged beyond repair, so I purchased a non oroginal replacement from ebay. The movement runs ok in "face down position", with amplitude about 270 and daily rate arround 0 sec/day. When I turn the movement in the "face up" position, the daily rate drastically increases (about +80 sec/ day) but the amplitude drops to about 190 degrees. When I move the watch bacj to face down, the thongs get normal anaing.
  4. For the date change you first advance the time over midnight. To acheive the quickset you should alternate the hour hand forwards (between 1 and 3) and backwards (between 11 and 9 o clock)...
  5. I did search the ebay, but didn't find 7s26 small diashock springs sold separately... Thanks Andrej
  6. Hello, I would need some 7s26 parts: - a diashock spring for barrel and train wheel bridge and if possible also a spare jewel (both are smaller than the ones on balance cock) - plastic day/date corrector setting wheel (737 300) I'm wondering if you have any for sale... Thanks Andrej
  7. Thanks for all answers, I have found the issue The problem was, that I have put some Tesa adhesive tape on the one microphone's plastic part. I did this to avoid scratching the watch - without the protection tape I could see (with loupe) the small marks on watch case. Without the protection tape it works ok Instead of the tape I can put a piece of paper or even a paper sticker (as on the photo) between the watch and microphone.
  8. Hello, thanks for the answers. I've got a Timegrapher No. 1000, about 8 years old. It seems, that there are at least 2 versions of the No. 1000 model. The difference can be seen, when you switch on the display: 1st version shows the daily rate only on the top of the screen. 2nd version shows the daily rate also on the main screen in 4 different horizontal display sections. I have also noticed that there are 2 types of microphone stands. One stands is more rectangular, while the other is more circular. If you look at the back, there are two versions of Frequ
  9. Hello, I'm wondering what is your experience with a 7s26 watch, when you put it on the timegrapher ? Does the ticking sound have enough volume, to be picked up by the microphone ? I'm using a standard Chinese timegrapher. When I put the whole watch on the microphone (for eg. my SKX007 or my colleagues seiko 5), the microphone has difficulties to pick up the ticking sound. If I put on only the movement without the case, there are no problems. So I'm wondering where could be the problem: The spacer between the case and the movement is plastic, which "isolates or w
  10. I have washed the wheel in Zippo fluid. Then I oiled it a little between gears with 9010. It seems to be ok. Thanks Andrej
  11. I have checked and unfortunatly I don't see any groove
  12. Hi, thanks for the answer. I know that it can't be taken apart. That is why I'm concerned that with cleaning I will also "wash away" the lubricant. I will search for the groove ...
  13. Hello, I have disassembled the Poljot 2209 movement. I would would need your advice, if it is ok to wash also the "double gear" and how to oil it later... Thanks Andrej
  14. Hello, in Mark's videos I saw that he is using Horotec watch hand fitting tools. I would like to know, which dimensions are most useful (for eg. for 7S26 and 2824 calibers). Thanks Andrej
  15. JohnR275, thanks for the answer. Sorry, I didn't explain properly. Mark didn't recommend Anchor oil in the video - he recommended other oils, and also different oils for different parts. But I used the Anchor oil and I used it to oil all the parts. Do you think that the main cause for my issues is the wrong oil ? Thanks Andrej
  16. Hello all, I have some issues with Eta 2824. As the amplitude was low, I have stripped the movement and oiled it according to Mark's video on youtube. I used only Anchor universal oil on all necessary parts. I manually wound the movement before assembling the date and oscilaltong weight parts. Everything was perfect (straight line, amplitude more than 300). A week later I started the same movment again and the amplitude was a litle bit lower (about 270). I continued with other assembly (date parts, dial, hands). After assembly the day rate and amplitude started to oscillate
  17. Thanks for the answers. I don't know it's origin, I have bought the watch in Europe, as a non working (problems with day change) second hand watch... My idea was to study the assembling / disassembling of the watch caliber. But I was hoping to get a 7s26, as this is written on the dial. Anyway, if it is a copy, there is no other info. If it is a Seiko standard caliber, I would like to know the reference number... Thanks Andrej
  18. Hello, I would need your help identifying this watch caliber. I have found this caliber in a Seiko 5 watch, which was surely franken (made from different pieces). The dial is 7s26, while the caseback has 7009 engraved on it... The writing on the rotor is 7009A, but other parts don't look the same as 7009 to me: - The bridge, which keeps the pallet fork in place has only one screw (7009 should have 2 screws) - There are banking pins present (7009 doesn't have them) - The day wheel was not working - it seems that the cover under the day wheel is different tha
  19. Hello, While working on my 7s26 I was watching the video "Conclusion Seiko 7S26 SKX Divers Service and Lubrication". At about 6.34 Mark is mentioning to turn the jewel upside down. https://www.youtube.com/watch?v=kHY_ysWq39o It is necesary to put the jewel into place with the correct orientation (up / down) ? If yes, how to know which part is upper and which is lower part of the jewel ? Thanks Andrej
  20. Hello, My name is Andrej and I came across this forum googling for watch repairs. I would also like to express my congratulatioins for youtube videos, which are very interesting. Andrej
