    No gasket. Measure the rebate dimension and fit the next size up. You should be able to press it in without using a claw.

    rodabod reacted to jnash in Is My L&R Varimatic Operating Correctly?   
    Hi, it looks like the machine is out of sync , instructions on how to fix will be on the manual if I recall which is online .

    Have done this a few times , involves taking off the cover and changing the arm location to hit switches that lift and drop.

    One thing to think about is how did it happen. This can happen if the arm doesn't high enough or got caught, this could mean it needs hydraulic fluid and could mean a leak..

    Your hairspring looks unwell. I would be looking for a donor movement to help.

    Generale Ressorts has a 1.30 x 0.105 x 280 ref. 3267 and a 1.30 x 0.105 x 300 ref. 3268. The latter is the correct length but you would be fine with the 280.
    What did you try to increase your amplitude before increasing spring strength? That should be the last resort after all else has failed. I also agree that 250 for that watch is OK if it's timing well.

    Since it's regularly happening every 8 seconds I'm thinking a gearing problem; the 4th wheel has 8 teeth in its pinion, which will equate to 7.5 seconds per tooth "in action"- but it would be odd that all the teeth on that pinion or the 3rd wheel that drives it would be damaged and damaged equally. Though if for example the train bridge was removed with power on the watch the 3rd wheel teeth may have zipped accross another component raising burrs or something.
     
    Is the train nice and free with the balance and fork out?

    Personally, I'd avoid the Chinese copy. Go second-hand Swiss. In all likelihood the Swiss tool will have superior build quality, tolerances, and material.

    My own documentation is BHI material and is copyrighted, so I will not share it, but that video gives a good description. It's important to realise what happens at the different phases of the escapement motion. If it's too much to take in at once, then start with the anchor escapement and advance from there. That is how escapements are traditionally taught, starting with the simplest.

    I’m inclined to agree with what JohnR says. But I’d also like to add some of my own cynicism which is that I think that the snake oil manufacturers will sell you anything if they can see a gap in the market. 
    But, I can see why it makes sense to have something very slippery and less likely to be pushed away than a light synthetic oil. That possibly is more important for high beat movement where there is a greater velocity. 
    With regards to “which is best”, I don’t think anyone should offer any opinions unless they have revisited work they have completed over a span of several years. I’ve been using 9415 for several years, but I’m yet to investigate its effectiveness long term.

    Depth of lock is something that you get a feel for when inspecting escapements. It needs to be deep enough to ensure that it is safely locked, and you can move the pallet fork across very slightly, release, and observe the “draw” to see what the action is like. 
    On modern watches like these, I very rarely adjust thw locking. On adjustable banking pins (or at least bend-able), you always have to check it and will often find that they have been mis-adjusted. It seemed to be a common misconception that opening the banking pins was a quick fix for mis-locking. 
    Bear in mind that if the pallet stones were moved to change the depth of lock then this also adjusts the drop. The angle of drop is wasted energy from the escapement as potential impulse is not translated into the balance while the escape wheel is disengaged from the pallets.

    I think you can get surprisingly strong joints with loctite when it is prepared correctly. Some of the formulas have a sheer strength greater than that of Araldite. A good example of that sheer strength (over a massively greater surface area) for me was when I managed to rotate my entire watchmaking bench when twisting a 1cm brass bar glued with Araldite to a seized case back. My loaded bench probably weighs around 100Kg.
    Another thing worth mentioning, when you come to re-fit this hand, I would use a flat-ended punch/pusher rather than one with a hole in it. That may seem obvious, but I sometimes use the same punch/pusher that I use for the minute hand as I do for the sweep seconds hand, where applicable.

    I can't remember using 603. I use 243 occasionally for some crowns when they do not have a very strong friction fit. Even that is pretty strong.
    If I were you, I'd try the stuff you have already. For application, I usually use a needle or oiler. I apply too much, and then wipe away the excess with tissue paper.

    The only issue I can see with using UV adhesives (apart from not having great experiences with it personally) is that I'm not sure that the UV will penetrate into the adhesive if it is already an interference fit.

    I recently used Loctite 603 for some watch repairs as it was recommended by the BHI for attaching wheels to arbors instead of soldering. I believe there may be an even stronger version.

    There are versions of Loctite which would work better than superglue in my opinion. Or Araldite even.

    I have used a piece of paper with a small slit. Starting at the collet and moving the paper in a circle to follow the coil . This keeps the tangled part above the paper and easier to untangle with tweezers as you rotate the paper and move your way outward.

    Thoughts?

    I usually let the balance wheel hang while the stud is still attached to the cock (which itself is mounted on a balance tack). Then I run a needle through the spring while holding the balance wheel steady.

    In my experience, clock restoration takes a lot of time, and from what I can tell, people don't seem to keen on spending a lot on them. Perhaps it's a reflection of the current value of clocks. I tend to do it as a personal hobby.
    Watch restoration is also time consuming, but there is potential to be quite fast through experience. What I disagree with is people who describe work as "servicing" when in fact all they do is dip it in lighter fuel, clean the bridges/cocks, and swap the crystal.
