The Brasso Scourge


JimmyD

Recommended Posts

A  few weeks ago this clock arrived at the clock shop, they had been cleaning it with Brasso, a no-no on gilt clocks.  The fly had a pin broken off, and a few bushes were needed, these French clocks pinions  are rock hard, well diamond hard, so I fitted a brass bush like collar that fixed it up without trying to drill the dam thing.  Anyway back to the Brasso thing, as you see it was a mess and a lot of the gilt was rubbed away, not a bother on a normal French clock that is not worth much, however I could see this was a goody so I did some research on' Valliant a Paris' and this guy was a master clockmaker between 1750's and 1810's. I found a few of his clocks and they sell for big money from 16,000 euro up. When the customer came to pick it up the front desk  gave them a note I had done and they had no idea about who or what it was and then asked him how they should clean it, he came and asked me and I said, tell them "by bringing it back in about 5 years time for a service". Now the clock itself has a flaw, have a look and see if you can pick it.

I have to agree with the previous speakers it seems this piece have met the floor at some stage and been fixed by a Quick and Dirty method. the left side is all of center with the right from top to toe only the stand is uniform.

Just out of curiousity, how common was it to solder the dial on like that, i understand by the looks of the work it wasn't a very good repair but still was it common practice?

I was going to say the soldering on the back of the dial looks like something I would of done when I was 13 with my dads electrical soldering iron, and the dial does not look square with the base, but they have both been commented on.

The pendulum rod looks ultra fine too, which I'm guessing is correct,but what diameter rod is used?

The movement has a silk suspension the pendulum rods are normally thin; it is the square brass block towards the top of the rod that fits into the crutch. Look at photo 3.

This is just showing what is wrong. Someone mentioned the solder, you are correct it is a bad repair.

Yip the key holes are off and the solder is crap, however when I took it apart there are no extra holes and the chapter ring (what I thought may have been altered) it also did not show any other pins than the one's present? There is also no other holes in the movement other than the mounting holes that it fits onto. The only 2 holes that did not have any use was the 2 that the backing plate bracket that fits the body to the case, however the bracket has the corresponding holes in it and when I looked closer one had the threads had been stripped, therefore someone made 2 new holes on the bracket. I was looking for a reason why the key holes are not right as this was made by a master clockmaker and did not think there is any way that he messed it up, however given the evidence of no other holes I am at a loss to find any other conclusion other than the best marriage I have ever seen. Below is a photo of the back of the movement, it does show the left winding arbour is higher than the right when looking at it from the back, thus the right is higher than the left from the front. You can just see the pinnion hole for the hands shaft which shows the distance is different.

Any other suggestions as it has got me stumped

I have put this photo on a grid in paint, the left winding arbour is an 8th of an inch shorter from the hands shaft than the right arbour is, also an 8th of an inch higher than the right arbour or one is 2 1/2 inches and the other 2 5/8ths from the hands shaft. Maybe someone with more skill than me in using these programs can check this.

It seem's it's not unusual for this maker for the key holes to be out of alignment with one another, it must be to do with the basic geometry of the movements, a good deal of the ones on the web exhibit similar characteristic some to a more alarming degree than this clock.

It has 'Vaillant a Paria' on the chapter ring I did a search in Goggle and he made high end clocks, one sold for 600,000 at auction and a few others 20,000+ he is also listed in Loomes book. That is why I do not understand the error in the movement. I looked at some of his movements on other clocks and they look the same, however most key holes are in the right place. I think I will contact a high end seller that has one of his clocks for sale to ask if this was one of his, hope I get a reply.

Most would suggest that like the clock you serviced not all are so can this be judged a error or simply a quirk of the movement design ?

Thats great. Has he asked for anything specific. Are you sending him the same photos as you put up here.

I have sent most of the photos on here and a few more of the movement.

    • although not in this case.  It was the Lugano Convention and its deficiencies that allowed a Swiss court decision in the first place.  This isnt really a Brexit issue at all.  A decision that affects both the EU and the UK should never have been heard in Switzerland. I bet the authorised service centres in the UK are pretty pleased.  It's a massive shame, though; I believe watch owners should be able to choose to have their watch serviced by whoever they trust.
    • Hi guys I think that old hippy is correct, it opens the gates for china to manufacture aftermarket spare parts. considering that they already do work on behalf of the Swiss I guess this decision gives the a little more legitimacy to tool up and I am sure they will take advantage of the situation either with or without the blessing of the Swiss watch industry  Having read about the protectionist machinations of the Swiss in the history of Europe they were the only ones to get fat at everybody else’s expense. I think the outcome could have been guessed at but ,  fair play to Cousins UK for standing up to them.  Now the question,  will everybody boycott Swiss watches and Swatch, no way they will still fill their coffers.  Me I stick with the Japanese once renowned for cheap shitty watches who came good through industrial effort and don’t for get the Russians that most dismiss as low grade crap. Wouldn’t buy a swatch product ever how about you all.? a
    • Hold the crown when in winding position, move the click away from the crown wheel, and then while holding the crown let it slowly unwind. I recollect that you must remove the automatic device bridge first, but maybe I'm wrong. You can first try without removing the automatic device bridge.
    • nevenbekriev- You nailed it with your description of me and my reaction when the clock started ticking again. I am a newbie.  I love the sound and idea of mechanical clocks but the idea of owning one and trying to keep them running has never appealed to me. My wife bought this one and an antique German wall clock.  When I looked into having someone repair them for me, the universal response was "it's really expensive to work on them, you should just replace the movement". So, I had nothing to lose, I started researching them and opened them up. The wife is happy because she hears the sound of the clocks again. But I have gone down the "accuracy" rabbit hole. In the vertical position, the balance wheel was not floating. It was sitting on the bottom of the frame. I adjusted the lower spring collet and got it floating. It easily passed the 270 degree 3 to 5 minute oscillation test. It took 8 minutes for the wheel to completely stop moving.  I put it the unit back in the movement and checked the safety pin. It does not touch the safety roller anywhere in +/-270 degrees rotation from neutral position. But the amplitude of the rotation with the spring fully wound is weak based on what you are saying. It rotates +/-90 degrees from the neutral position.  No, I did not take the movement completely apart.  That seemed way outside my skill set at the time. There is a reason I became an electrical engineer and not a mechanical engineer. I am much more comfortable with moving electrons than tiny moving metal parts. Will I do it in the long run? Anything can happen. I don't seem to be able to let it go.
