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.

Old Hippy, thank you for your help.   I removed the escape wheel and pallets and checked the pivots and holes.  To my eye they looked good.

      Revue 30 Balance wheel
      By Ballefrostt
      Hello
      A friend of my father gave me this old pocketwatch to see if I could repare it. 
       
      As you see in the picture, the balance wheel is extremely bent. I tried to bend it back, but i cant make it good enough.
       
      Does anyone know where I can find a balancewheel for this Revue 30 movement? I have tried to search around online, however, I cant find any.
       
      Is there a generic balance that would fit in here? 
       
      Best regards
      Nicholas

      Mark Lovic’s “Watch Repair Lessons & Courses” (mini review)
      By VWatchie
      I’m working myself through Mark Lovic’s “Watch Repair Lessons & Courses”. Before enrolling I wasn’t sure the courses would be worthwhile to me, as I had spent a huge amount of time researching the Internet on how to service watches, and had serviced several Vostok 24XX movements (very affordable movements, BTW).
      Now, in hindsight, the courses have proved to be extremely valuable to me. I’ve learned things that I just haven’t been able to find elsewhere, like how to easily transfer watch oil from the bottles to the oil pots, how the get the right amount of oil onto the escape wheel teeth, how to remove rust from pinion leaves, that I shouldn’t oil the pallet fork jewel bearings (and why!). The list could be made very long.
      Anyway, yesterday I finished the level 2 section of the course, named “Lubrication and Re-Assembly”, and as I beheld the magic of seeing the movement come to life again I shoot a slow-motion video of its beating heart, i.e. the balance wheel. For anyone interested you can see the video here.
      Thanks for reading!

      Replace a complete balance wheel and bridge for ETA 2804-2
      By hokavan
      Hi all,
      I broke the pivot of balance wheel on ETA 2804-2.
      I bought a generic complete balance wheel with bridge for ETA 2824-2 (http://www.ebay.com/itm/262234041099?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) and tried to install it without any difficulty. There is only a difference between the new and old one is the shock assemblies (Incabloc vs Novodiac). In the photo below, the new one is the yeallow on the right hand side.

      My question are:
      - Is the complete balance wheel and bridge replaceable between those movements?
      - If Yes, after installed, the balance wheel has swung a little bit then stop. What is the reason? How to fix it?
      Thank you

      Help with balance wheel of Landeron 48 movement
      By GeorgeClarkson
      I am in the process of servicing the Landeron 48 movement that came with the complete watch with wrong dial applied, as many of you can recall from my other thread. After a brief check I noticed something was wrong with the balace wheel, so after inspection of the part, I discovered that the upper pivot was broken.
      I had another balance wheel with bent hairspring, so I decided to replace the balance wheel using the original hairpring. After a bit of tinckering, I managed to do just so, but a new problem arised, which will be shown in the linked videos here below.
      The first video shows how the new balance wheel turns freely after a bit of adjustment in the movement:
      The second video shows the problem I faced after replacing the hairspring onto the balance wheel and reassembling everything back together. Basically, the amplitude is extremely low, but I cannot figure out still what can be the problem.
      The second video above shows the issue better than a thousand words...
      I need the help of the experts, here: what can the issue be? I followed all Mark's videos on putting the watch in beat, checking the pivots, pallet stones, everything. I have never seen such behaviour before. What can it be?

      What sets the balance wheel into motion
      By Carramrod
      I'm relatively new to mechanical watches and have quickly become fascinated but have an elementary level question that hopefully someone can answer.
      If the hairspring and balance wheel come to a complete stop due to the main spring running out of power, what is it about winding that sets the balance wheel back into motion?  I understand the way the escapement works once it is in motion to input a small amount of energy into the balance wheel, but don't understand how winding alone sets it back into motion.  I know with grandfather clocks you have to restart the pendulum manually and I'm wondering why this isn't the case for watches also. TIA.

      Hello all, Very, very new to this watch repair lark but reading and Youtubing my way along. No doubt you will see some exceedingly stupid questions coming along from me shortly. Thanks.

      Center Seconds Hand Support While Installing

      By ricardoch · Posted

      Hi all, I have had to install several times second hand on my omegas (10xx) that were a pain due to their soft spring. I have not an omega holder, so I made my own "tool" from a piece of copper wire with the end filed flat. I removed the auto weight whose axle lays just below seconds pinion, and dropped the wire to just lay on the seconds pinion. Then marked the wire where it exits from the rotor hole and bent it from the mark to make an "L" with the shaft measuring just the length from the rotor base to the seconds pinion. Let it go through the rotor hole and check that shaft goes all the way down, to ensure no pressure will damage the seconds pinion or axle.   Simply lay it on the movement, support with a piece of tape and lay the movement on a flat surface. with the new "L" tool lying on the bench. The seconds axle will remain in place while installing the hand. Not a high tech solution, but it served me. I hope it helps you, taking care to not miss axle length, better short than long Sorry, but I have not better photos, I did new just to give you an idea. The last two are the actual size and position on my watch Regards

      Just a brief Hello, I have not been active on the forum for some time but without going into detail there have been a few health setbacks and deterioration of sight has not helped. Ironically I have just recently been given an excellent watch makers lathe and am enjoying my practise with it.  I am still tinkering but it takes much longer than it used to. I have an ancestors company verge fusee pocket watch in pieces at the moment, it is signed but as with these items probably not much of his own work gone into it.  I will be working on it from time to time but parts may be an issue. Also an Omega bumper is in pieces, cleaned and ready to work on.  So not quite written off yet. If anyone is interested, John Robey has published a PDF on Academia about Sam Harlow, one of my Ancestors from the line of Ashbourne Clock and Watchmakers,a Long Case Clockmaker.  Its quite interesting, obviously to me, but others may be interested, I may have a word with him and get permission to put it on the Forum for folks. Anyway, hello to everyone for now and I will be popping back again from time to time. Cheers, Vic

      Balance not rotating anymore

      By watchweasol · Posted

      What Joe explains is good practice as it tests the balance and allows good observation of the same   and not having to worry about the fork engagement as the balance is free swinging.
