Hi All. I am in the process of restoring a full hunter fusee pocket watch. I have stripped and clean all parts and have re-assembled. The fusee chain is installed and the watch with a few turns on t he fusee wheel works and keeps pretty good time considering its age. There is a fault though the fusee chain flips off the barrel when wound to just over half way. Any ideas on what can be done to correct this?

Many thanks

When you say flips off the barrel. Do you mean the chain unhooks from the barrel. If so make sure you have the correct end of the chain attached to the barrel. Is the hook seated down on the barrel and is well hooked in the hole. Is the hole worn or even the end of the chain worn. The chain must be in line with each wind to the fusee line so it sits in. When the watch has run right down you shouldn’t be able to move the chain on the barrel, if so it needs you need to wind it up more by releasing the ratchet wheel, give it a few clicks and test.

Fusee chain. Outside hook fits the barrel inside hook fits the fusee cone.

Hi All

Oldhippy: Firstly I believe the hook is disegaging from t he barrel and I may have inadvertently fitted the chain the wrong way round. I think I installed the chain like this.  The outside hook with the horn on, I have in the fusee cone and the hook you show in the centre is in the barrel. Is this wrong? I will check tomorrow and let you all know if I have indeed put the chain on wrong. Many thanks to all for replying and giving me your help.

Hi  All/

I have indeed put the chain on the wrong way round. The word dipstick comes to mind here as I took a photo of the chain showing the correct way as I removed it. No excuses. Once again thanks for all your help.

Unless one works regularely on same caliber, taking pictures can be priceless, I have always practiced and adivised it. The only time I get baffled is when I end up with extra parts.:unsure:

Best wishes.

I'm not brilliant at doing the vids as I've only got a phone. I will get some kit so I can submit something a little more professional.

Hers a little history. The watch was left to a friend by his father and was his great great grandfathers passed down to the next generation. My friend has never seen it running and it was left neglected in a drawer uncased.

The watch case and chain was totally tarnished almost black. I wish I had taken a picture. I had to work out how to strip the the works out of the case and found the little retainer pin at 6 o'clock which you have to push in to release the works and tilt up on  the hinge at 12 o'clock. The movement was totally gummed up and very dirty. The chrono mechanism which hacks the balance, (the slide switch on the side of the case), was seized. The chain links were also very stiff. In order to split the top bridge from the bottom bridge I had to twist off the motion work wheel from the adjustment staff which is an interference fit. It was a touchy moment as I did not want to damage the wheel. Once I had everything stripped I cleaned all the parts in an ultrasonic bath using elmo  degreaser. The chain was a task, I left it naptha then dried and left it in thin oil for 2 days. Wound it on a thin bobbin of wood to free up the links. After a few wind unwind ops the chain began to free off and I repeated the cleaning and oiling three times. No the chain is functioning perfectly. It is a long process and you need patience but the end result was worth it.

I cleaned the silver in lemon juice and cola. Washed in warm water then buffed with a jewel cloth. Didn't want to get rid of all the patina so left a few traces. Freed off the chronograph hack switch on the case.

Really enjoyed myself and the result was very satisfying.

 

Thanks to all here who gave me advice it was very much appreciated.

I have a question. Does anyone know what the pendant is for as shown attached to the chain in  the last video. It has a RED and Green glass on each side and spins about the centre. Is it a railway pendant that mimics the signals STOP / GO?

Thanks

Just to allay confusion the video showing the fusee chain laid out, I described the hooks position the wrong way round. The hook with the horn should be attached to the going barrel, the plain hook to the fusee cone. Sorry.

      Venus 178 hour counter creep

      By watchfellow · Posted

      Hi everyone, I put together a Venus 178 recently, but found that the hour counter "creeps" ie. runs when the chrono is disengaged. This is the similar type of setup as the Omega 861, where the hour counter is driven off the mainspring barrel, but stopped when the chrono is disengaged by a friction spring.  Am I correct in assuming that the friction spring for the hour counter driving pinion should be dry? I am guessing that the issue will be either the spring or the driving pinion, but while the driving pinion has some wear the spring looks decent.  I've attached a couple of photos in case anyone has any tips. Thanks in advance!

      Setting power reserve on LeCoultre Futurematic

      By watchfellow · Posted

      Thanks everyone for the replies. It seems setting the hand is a bit of a guessing game, and I thought there would be a very specific way to do it. Since the reserve indicator hand moves clockwise as the spring is wound, I tried setting it right at the start of the black side. But setting it there doesn't really make sense, because by the time the spring is halfway wound, the hand is only at the end of the red side... In my head halfway wound shouldn't mean the hand is still "in the red."

      Lovely part of the country! I spend most of my days driving along the A64 for work in and around York. I'll be sure to drop plenty of questions soon! I've actually got a couple of watches on the way that I'm pretty sure I'll need some help with! They look pretty beat up from the pics but I love a challenge and an excuse to buy more tools 🤣

      Help - London Elliott Mantle Clock Night Silence

      By oldhippy · Posted

      I have two of these in my home. You need to remove the movement from the case, take off the hands and remove the dial and take a few good photos of the front plate so I can see what the problem is. The round nut unscrews and the hands pull off pull them off from the center and not the tips as you could break them.
