      My name is Matt, screenname MattHH. I was asked to look at someone's watch because it needed a battery or capacitor IDK. Anyway since I was successful I caught the fix every watch that is broken bug. I started with pocket watches,then watch tools e.g. staking device, and then wrist watches. I got a lot of practice buying boxes of watches on eBay and working on them and if I messed it up it still a learning experience, like reverse engineering and some common sense go a long way. I play hell getting the balance wheel in anything though. To save money I am focused on the Benrus watches because I think they are cool looking and cover most of the bases e.g. dive watches, military, formal, informal, amazing, and the weird. It would be nice if the manufacturer of watches made repair manuals like cars, that would be paper gold. Here is a few Benrus watches on my wish list. Going from fixing diesel engines to watches is heaven on my back. I had to learn the hard way going from gorilla to butterfly on the screws of a watch. Glad to be here! Matt from Clearwater, Florida

      Hello once again. I have this YSL 5421 quartz watch which wasn't opened for about 10 years and I just can't open it, since I am not sure whether I should force it or is there any trick that I can't see how to open it, and I rather ask you how to go about it. I have the knife and a watch pray type opening tools, but this back seems to be shot real tight and hope I won't have to buy the $100 case back opening tool at this stage of my hobby, although Since we are on the subject I would love to know which one you think better or preferred for future consideration. Thank you

      Hello All,
      I am new to this forum and relatively new to repairing watches (so please don't bite!).
      I have repaired a couple of cheap watches before and both have worked out fine so decided to try my hand on Benrus I have had for a couple of year and am quite fond of.
      All was going well and then I had a pet related incident whilst opening up the mainspring barrel. By the time I had found the barrel (cap, arbour and mainspring conveniently ended up in my lap) it had been damaged and some of the teeth destroyed.
      I have tried to identify the movement in order to figure out what part to try and find (picture attached, apologies for the poor quality) but really struggling as it doesn't look like any other Benrus movement I have seen anywhere online.
      The watch has 1974 on the back (looks like a "length of service" gift awarded to someone by the inscription).
      I bought it from ebay and the seller doesn't know anything more about it. If more picture of any more of the parts would be useful please let me know.
      I'm just hoping that someone will be able to help.
      Thank you in advance.

    • Thanks for the reply and comments. Noted on the oil for cutting, that's certainly a lesson learned. I used a little oil on the second cut, and a thin wipe of oil on the cutting broach, once I had learned from the original mistake! The bushes I used are shown in the screen grab. They may have been a bit shallow, but they already had the oil sink and I did not have a tool to cut one. I guess If I had a bit more experience in this, I would have chosen differently. Still, very good to know what alternatives there are. The broaches are almost certainly too small for anything larger, I agree. Now you have peaked my interest - invisible bushing? I had come across scree-in bushes... Off now for a read-up! Many thanks for your support and kind words (and, to all who commented). I doubt I would have even attempted it otherwise. Now I have, I have learned something new and hopefully (when I get all together again), will have a working clock at the end of it.
    • With the pallets removed, does the train feel like it’s running freely? And how about as you increase the winding power? If the power delivery looks respectable, then I’d check for something else obvious like mis-locking. How do you adjust the banking pins in terms of their orientation? I knocked up this crude little brass tool recently for correcting some banking pins on a JLC. It’s easier with modern movements are you are more or less just uprighting them. 
    • I have used DX for keyless work for several years, since Mark recommended it : 
    • You have a gem there! That Wittnauer is really a lovely piece, and I like the transistor symbol on the dial. Reminds me of when I was a kid in the sixties, and having a “transistor radio” was a Cool Thing. I see that the drive mechanism is very similar to the Luch electromechanicals. On a related note, one of my Luch watches is engraved on the back too... in Russian, so I have no idea what it says; but yeah, every one of our watches has a story. Cheers, Gryf
    • Okay so the cap jewel was placed the wrong way and the dome went inwards... Should've checked that earlier... Thanks for all the answers!
