Chelsea clock

Does anyone have any suggestions about how to get this clock to run?  It is a Chelsea ship’s clock.  When I got it it would not run, but I attributed that to the fact that it was dirty and had old black oil around the pivots.  I carefully cleaned the movement and cleaned the balance wheel separately in naphtha.  It reassembled without problems and was oiled,but would not run. If I “add power” to the movement it will run.  

I looked at the mainsprings while it was dissembled and they looked clean and intact.  

I have included pictures of both sides of the clock and a picture from the side showing the wheel (the one pointed out by the screwdriver) that I can push on to make it run.  

Thanks in advance for any help with this vexing problem.

You need to let the power off both springs and check for wear in the holes that the pivots go in. Pay particular attention to the escape wheel and pallets in the platform as I see it is not a fully jewel platform.  The metal that are in these types of movements are not that hard, the steel is quite soft so pivots also could be worn.

      Movement inserted from crytal side

      By Zedster · Posted

      Thanks, This watch was in a box of old scrape units that a friend gave me. They used to be his late father's who was a watchmaker before the war and then continued later in life. I picked this one out as it looked like it had potential, and I liked the dial, it's been a bit of a learning curve for a beginner but I was determined to get it going. Now I'm on the final lap it feels good. I'm just wondering whether to invest in a decent set of hand placement tools or stick with the cheap Chinese red thing I have, decisions decision 😆

      Landeron 248 hammer and cam interaction

      By Klassiker · Posted

      An update, for everyone who contributed advice, and for those who come after with a similar problem. Based on the answers received, I decided to work on the face of the hammer first. I used a square degussit stone to guarantee a vertical surface to work against, and ground the face back until it was square across 90% of the depth. I was conscious of the risk of removing too much material.* After I'd got the shape how I wanted it, I polished the surface with lapping film. To cut a long story short, it did the trick and the hammer hasn't slipped off the cam since. Of course, that wasn't the end of my problems. Have a look at this video and tell me what you think is wrong. https://youtu.be/sgAUMIPaw98 The first four attempts show (0 to 34 sec.) the chrono seconds hand jumping forwards, the next two attempts (35 to 47 sec.) seem "normal", then on the seventh attempt (48 to 54 sec.) the seconds hand jumps to 5 sec. and the minute counter jumps to 1. The rest of the video just shows repeats of these three variants. I solved it by rotating the minute counter finger on the chronograph (seconds) runner relative to the cam.  I'd be interested to hear your opinions on that. It seemed to be the right thing to do, but maybe I've introduced another problem I'm not aware of. * What is the correct relationship between the two hammers and cams, by the way? Should both hammers strike the cams exactly at the same time, or is it correct for the minute counter hammer to be a bit behind the seconds hammer? In this picture, I removed the adjusting screw at 1, and the hammers are contacting the cams simultaneously at 3 and 4. I had to turn the screw down tight to achieve this condition after stoning the seconds hammer and replacing the bridge.

      It was easy enough to pop off. Once I had the cannon pinion hanging on the blades of the stump, I got my #2 tweezers on the gear attached to the staff and levered it down. That way none of the force was on the brass wheel itself.   I reinstalled it and the bridge, and it looks like a small but reasonable amount of end shake. It also spins easily with a blower. It stops quickly, but I think that's due to the large shoulder and about what I'd expect from this wheel.

      Oh, right. For some reason I was picturing a monocoque case in my head. Good looking watch!

      Well said Ross. My reason for the thread, i like many of us dont want to lose the forum, such a well knitted group of individuals i feel. But things can happen out of anyone's control. Would be nice to have something in place just in case, if anyone has any ideas please speak up.
