  1. When working with this movement for illustrating the lessons in my Watch Repair Course, I have perhaps stripped it down and re-assembled it some 5 or 10 times in the past month. The last time I did this was during the Live stream and once it was assembled the watch gave a very low amplitude. I did not show this in the stream as it was then past 10pm and I had dinner waiting for me, but when I came back to the movement the following morning, sure enough it was running with very poor performance. The performance picked up just as soon as I slightly loosened the balance cock screw and so this led me to believe that the balance staff had no end to end play (called end-shake). My initial thought was that, this being a clone movement, maybe it was fitted with different sized end-stones. I had removed both incabloc settings during the live show and so, I wondered if I had replaced them wrongly - as you can see, they look identical - but sometimes you do get them with slightly different thicknesses and, 1/100th of a millimetre can make a big difference. In this situation, replacing the incabloc settings the wrong way round can cause exactly the symptoms I was observing. After checking that it was not an even simpler problem - like a rogue hair lodged in the balance spring or the like, I took out the incabloc settings and swapped them around. Confusingly, this did not resolve the problem. In fact, the watch movement was running with just the same low amplitude performance. Again, loosening the screw resolved the issue and so, yes it is definitely an end-shake issue. I removed the balance and took a closer look and noticed a small dot in the lower main plate where the balance cock sits. Once little trick some watch repairers will do in order to make fine adjustments to the balance end-shake will be to make a bump in the metal where the balance cock sits in order to lift the balance cock very slightly upwards and allow the balance staff more play. This practice is frowned upon by many watch repairers but other watch repairers who try to keep repair costs down for their customers will have no problem with it - the purpose of this video is not to open a discussion about wether this is good practice or not, but I was fairly surprised as this movement was brand new when I purchased it and had never even been installed into a watch case. I have another of these movements and so I thought I would take a look and see if that had the same issue, and sure enough - yes, a small dot where the balance cock sits indicating that the Chinese manufacturer for this Seagull movement makes it common practice to make fine adjustments of this sort. The purpose of this video is to point out this issue. I am sure that after removing and re-fitting the balance assembly several times, I had flattened the dot made by the manufacturer to a point where I had reversed their adjustment. A simple case of making a fresh dot with my screwdriver, allowed the balance to be lifted up and now the movement is running like a champ again. On the whole, these Chinese clone movements are very good, especially for the money you pay for them. However, they do not come without their quirks, and this is one of them. I hope you found that information useful
  2. Hi Mark,  there's a guy "takingblame" about to sell tweezers on the forum, you may wish to intervene.

    Cheers,

  3. In searching on internet for spare parts i found your videos, and i saw you reparing one Eta 7750.
    I am from Portugal and do all the repairs on mechanical and quartz wrist watches, and old watches, those ones in our great grandfather´s living room.
    I have dificulties in buy new parts for repair some watches, because all the brands like Omega, Tissot, Rolex, Citizen... does not sell any spare parts, not even a screw.
    Now i need one ball bearing Eta 7750 and can not find anywhere here in Portugal.
    Do you know where i can buy new parts for watches, if you please.

    best regards

  4. Agreed. I believe you need to press down on the screw after loosening it as the setting lever spring is keeping the setting lever engaged.pressing the screw down should force the setting lever away from the notch in the stem Sent from my iPhone using Tapatalk
  5. Yes. In your edit profile but if you have problems then please do open a support request and send me your new email and I will update it for you Sent from my iPhone using Tapatalk
  6. Register now to watch my first live broadcast. I will be broadcasting live tomorrow (Sunday 11th June 2017) at 1PM UTC (8PM Thailand Time) - I will strip down and reassemble a mechanical watch movement.

  7. It's a common enough problem. And of course, if it's not dealt with then it can get to the point where the sideshake causes the barrel to foul the centre wheel. Sent from my iPhone using Tapatalk
  8. The only problem with jewels is their expense. Plus, not always easy to obtain certain sizes for barrel arbor diameters. And finally you may find that the barrel bridge material may be too thin to support a friction jewel in certain movements. If the wear is minimal then it may be possible, although not attractive, to use a hole closing punch then broach and smooth broach in order to open to the desired diameter, smooth broach creates a kind of hard skin on the metal. Using bushes may not be desirable if the metal is too thin. Sent from my iPhone using Tapatalk
  9. Yep. It was a struggle before when I had a full workbench. But now I work full time on this project it's easier. However, it's still amazing how many hours can go into making just a few minutes of video. Sent from my iPhone using Tapatalk
  10. That's not surprising as majority find WRT via my watchrepairlessons Facebook page or the watchrepair channel on YouTube. Everyone has to start somewhere. If I had the time I would love to find a partner to do the same with clocks that I have done with watches but my workload is just simply too high. Clickspring on YouTube produces stunning videos but is not geared for repairs and restorations. Sent from my iPhone using Tapatalk

  12. Unfortunately this is a problem with many forums I frequent. It is up to members to clip their quote when they post but most do not - wether its this site or any other. If quoting a long post then it is better to highlight a particular paragraph from that post and quote just that paragraph that way many people will quickly see what you are referring to and it can possibly reduce confusion

  14. What @clockboy said. Just avoid 5 minute epoxy as it may not give you enough time should you place the spring incorrectly.
  15. Because many are quite expensive, peoples opinions will be fairly subjective. I like my apple watch as it fits in with my Apple eco system very well. However, if I was a Windows/Linux, Android user then the Apple watch would be useless to me and I would have a very different opinion. And yes - I do wear an Apple watch on occasion lol - ask user @jdm who was a recent witness to this atrocity.
