@AnalogDave Год назад

My inspection process is not adequate yet. I knew this, but I just don't know all the things I should be looking for. Videos like this really help me in my journey. Thanks.

@watchrepairtutorials Год назад

This series of videos that I’m doing right now is really all about pointing out the different things that can be incorporated into the inspection process. For example, on this movement, if I had done all these things during the disassembly, then I would know that the barrel is fine, so in the troubleshooting process, that would be eliminated as a possibility. As we move through looking for amplitude, all these videos will incorporate things that should be done during the disassembly, so that when the balance wheel goes in it is really just a matter of regulating the watch.

@rossjackson3670 Год назад

@watchrepairtutorials Год назад

Good to see you again, Tom. The real purpose of the series of videos that I’m doing now is really meant to aid in developing an inspection process that you would use during the disassembly, and in some cases the reassembly. Right so all these things that I just did, if they had of been sorted out during the disassembly and corrected, and you know that this area of the power train is good then, when you do end up having to troubleshoot, you don’t have to go back and redo the barrel like I just did. Ideally, you want to discover these problems during the disassembly, and then, correct, clean, assemble, and regulate.

@leowatkins3718 Год назад

Low amplitude may be due to several faults ( on the same movement )! not the answer I wanted to hear. If you want a movement which is almost guaranteed to have these faults look no further than Seiko's 7009, warning, working on these movements can be totally deflating. I have nearly changed my hobby as a watch maker to a dealer in watchmakers used tools a couple of times. This channel is by far the best I've found, my tip of the day... watch each video more than once. Thanks Alex.

@watchrepairtutorials Год назад

I can feel the pain. 7002, 7009 and even the 7S variants CAN all give a ton of amplitude issues. So much that it seems that the vast majority of people who work on them regularly will typically settle if they can get around 230-240. Thank you for you kind words Leo, and don't give it up.

So many great tips! Thank you. On those T brace mainsprings, I always use a slightly smaller winder cup than I need and then leave about 1/4” maybe 3/8” of the mainspring hanging out. I then fit it into the barrel ensuring the tab is in the slot. I then hold the brace down with tweezers with one hand and release the spring with the other. A bit to juggle at once but it usually works the first try.

@watchrepairtutorials Год назад

Not bad not bad I may have to try that. The only issue I would see might be in the spring filling up the winder too tightly.

Marvellous, just completed my first barrel bridge hole shrinking using a freshly acquired Boley staking set - couldn't have done it without your insight. Been gradually seeing amplitude increases in my work thanks to your excellent tutorials, the watch that required shrinking was kicking out a very respectable 230 degrees DD/DU, which for a 7625 Seiko is pretty healthy - sadly it would drop down to the mid 150s after 24 hours. Suspected some excess play in the barrel and it did look excessive on re-examination. Just waiting on the broaches arriving to bring the holes back down to take the arbour and then a polish up with a cocktail stick.

@watchrepairtutorials Год назад

It’s always great to see you hear the comments. I’m really excited about showing what I’ve come up with as I think that it is literally a game changer because it adds the element of the spinning basket along with the ultrasonic, which is one of the things that makes the high-end machines so effective. I have a little bit of experimenting to do first but I really think it’s going to elevate the cleaning process for home watchmaker. This is the third or fourth version of the pivot polisher that Ray originally came up with. He has a retired engineer he’s always looking for ways to improve on the design almost to an obsessive level but that’s just the way analytical minds work.

@awdturbopowah773 Год назад

Hey Alex, appreciate the insight and new knowledge as usual!! I did want to also share however a method of installing T-end mainsprings which I read online and tried, which has finally has saved me pushing the mainspring around the inside of the barrel (which I have found often does indeed score the outer wall of the barrel leaving brass shavings floating around inside the barrel). You get the mainspring almost completely wound into the winder drum, but leave 1/4”-3/8” of the tail end of the mainspring not wound into the drum. This way, the T-end is exposed, and you can actually hook the T-end of the mainspring into its slot in the mainspring barrel before fully pushing the mainspring out of the winder into the barrel. The only stipulation then is that the winder drum you use has to be of a small enough diameter to allow the tail end of the mainspring to slip between it and the ID of the barrel wall, but that’s not usually a problem since the mainspring is so thin anyway. Just figured I’d try and give back for all the learning which you’ve provided, thank you!

Hi! Do you remember me? After a lot of studying, I can now service my favorite vintage watches myself. Nevertheless, I've been whining for almost half an hour in the process of reuniting the gear chain.. Understanding the mechanism by which the key points of the clock work, pinpointing exactly what's wrong with the vintage movement when it's not working, seems a little bit possible now. I think it's thanks to you who taught me little by little how to clean using IPA, who was confused about what to do first.

@watchrepairtutorials Год назад

Of course I remember you and it’s good to hear from you. The study of serology never ends, and we all have something to learn. As the problems we work on become more complicated the studies also dive deeper into how the movement does what it does. Keep at it.

It is terrific that he found an additional use for the the GalaxyPro pivot polisher at 27:10. I recall.polishing arbors by hand which can take quite awhile and is difficult. Alex has managed to cut another process time for repairs. Is there any reason why one could not also lightly burnish an arbor using a burnishing tool?

@watchrepairtutorials Год назад

As you may know from a previous video, I would polish the arbor by holding it in a pin vise and use my rotary tool with the pin polisher to go around the arbor to polish it. This just basically reverses the process. The ultimate way to do it is in a lathe but I don’t have one anymore.

Great channel. I think I watched everything you put out there and some I watched like 5 times (regulation... ). I think its time I get a staking tool and I looked on your web for recommendation but I did not find anything on staking tools. I looked on vintage ones but they are so expensive and not sure if they are complete, bent... so on. I do not know much about China made ones either. I think it would be great if there was a video about staking tool and what to look for when choosing one. Thank you again for your channel

@watchrepairtutorials 6 месяцев назад

Thank you. Staking hats are worth the investment. If you could find a good one and even the vintage ones are much less expensive than a brand new one. You do have to be careful to make sure that the punches are in good condition. Depending on what you work on the Chinese version might be suitable for replacing balance, enclosing some holes in newer movements, but if you’re gonna be working on vintage watches, specifically older pocket watches that a good vintage staking set will give you all stumps that you need. I probably won’t be doing any staking set lessons on the channel because I’m doing two complete lessons making course on using the staking set, including all the different types of repairs that can be done with it.

Alex, this was super terrific. Would you consider making a video about how to close pivot holes in all different situations? Also, I've spent more money than I want to admit buying two Moseley Staking Sets in wooden boxes. The first was fairly complete (punch and stakes), but lacked any of the 20-something stumps. The second (less than half the price of the other, only about $150) had no punch, but had a full set of stumps, 3/4ths of the stakes, and a nice box with an unfortunate non-matching handle (also an ancient and browning pamphlet/booklet by Moseley showing sizes, etc., probably hard to get). I'm thinking, between the two sets, maybe I will have a nice representation of stakes and stumps. One or two are broken. I've also bought an ultrasound cleaner like yours, so I'm preparing to clean these up and to refinish the boxes (which deserve refinishing).The punch has no moving, upper handle; it just has a hole! I want to learn how to use these stakes/stumps and how to put in rivots. I'm using the transcrips of your presentations, editing them in Word to correct formatting and grammar so that they match exactly what you said with how you said it, and creating a book (several books, before I'm done). This helps me to absorb every word you say, every concept you give out. I guess I've spent (besides the staking sets) $1000 (besides the microscope, barlow lens, light, ultrasound machine). Oils and grease alone is shockingly expensive. Now I've got to produce something, some sales somehow on eBay, before my wife divorces me over all I've bought. She is understanding, as understanding as a wife can be who doesn't understand anything I'm talking about when I describe something exciting to me regarding watches and clocks.

@@michaelmmontuori well, there are some identifying factors that you can look at when you’re taking screws out. Many times bridge screws will all be the same. Some screws can be identified by the part being screwed down. The screw hole in the part might have a chamfer in it telling you that the screw head is beveled so that it sits flat when it’s in the hole. One of that you just have to pay attention to what the screw looks like when you’re taking it out.

@daveellis608 6 месяцев назад

Hey Alex, Once again, just wanted to say thanks for great content. The value I get from both these videos and your course, which I'm working my way through, is tremendous. I actually have a question regarding the specific target number for amplitude. Why 270? My assumption is that given that the slope of the power delivery curve for a coiled spring is steepest at the beginning and end of its wind respectively, that 270 or above puts you in the stablest position of adequate power delivery for the longest period of time, thereby minimizing isochronism (hopefully using that term correctly) and positional variation. However, that's just reasoning from a background in physics, and I don't actually know if that's correct, or if there is some other reason this is an ideal target number in the watchmaking space. Very interested to hear the actual reasoning behind this. Hope you having a wonderful holiday season with family and friends, and thank you again. Dave

@daveellis608 6 месяцев назад

And by minimizing, I mean maximizing isochronism (still not sure I'm using the term correctly)

@watchrepairtutorials 6 месяцев назад

270 I kind of the minimum for amplitude for isochronism. When a movement runs at 270 in the horizontal position and then goes to a vertical position, amplitude naturally drops 30-40 degrees right. That puts the vertical amplitude around 220-230 which is the sweet spot for amplitude because it cancels out or at the least minimizes any poise error that may be present.

@daveellis608 6 месяцев назад

@@watchrepairtutorials Awesome, thank you!

@loungebiddle7922 Год назад

One question for you Alex, I don't expect this to be easy..., I noticed my desire for perfection is ever increasing (I discarded this concept a long time ago, you know perfection not attainable, 70% of effort waisted trying to achieve it etc., often ends in a F up) So, question - how do you decide when the amplitude is going to be as good as you can get it? Noticed comments about some Seiko being lower. I can verify that but am I possibly overlooking an issue? I, for example, do not yet polish pivots. Have seen your tool to do this. Is there a % lost with a yet to be polished pivot? I do only work on vintage so I guess I can spin this question another way. Can a hobbyist get a 50-60 year old watch back to manufactured specification? Or say, within 10%? Hmm, as I type I realise this is just going to have to be my own call on this. I also noticed that 270 is a nice number to attain. Could I ever hope to get a Moeris 10 1/2 CD movement, 17 jewel operating at say 250 (that's within -10%)?

@watchrepairtutorials Год назад

One of the first things that I learned is that I watch is what it is. In other words you can’t gold plate, a pig. I was taught that as a watchmaker the number one goal was for the watch to keep an accurate time on the wrist. We never worried about a watch being in perfect poise because watch, you can still keep time without being perfect. We only strive for perfection with the movement warranted that type of service. One of the major factors is obviously the quality of the movement itself. So for example, you can’t expect a Seiko 7002 to perform at the same level as any American made railroad watches. It’s not so much the age of the watch as the quality of the manufacturing when it was made. I have had, and worked on many railroad grade watches that ran at a higher standard than modern Rolex watches. They had to because peoples lives were on the line. 270° minimum allows the watch to run at peak isochronism. This is the Swiss standard. It is based off of math and physics so it’s not really a debatable concept. Second watch collectors have accepted the fact that older movements require too much work to get amplitude up to that level so it has somehow become the norm but if they’re happy with that and the watch keeps decent time on the wrist, then it really doesn’t matter right? I would say to just do the best you can with what you have to work with, and don’t kill yourself trying to goldplate a pig. Save that for the movements that deserve the attention. Alex

@@watchrepairtutorials Thanks Alex, thoughtful response. I wondered why wife, who is English, uses the term "lipstick on a pig". I think I understand.

@kswaminathan5439 3 месяца назад

Hello Sir, Trust you are doing fine. For checking amplitude, most watch mskers use Weishi machine which is very expensive, I understand. Any other alternative to this? Please advise. Thank you Sir.

@watchrepairtutorials 3 месяца назад

Yes, I use the eTimer. It is similar to the more expensive Weishi software but comes in around 400 US . It runs on a PC and has many of the same functions with the exception of scope functions and some of the more specialized functions. One thing I like about the eTimer is that you can calibrate it from the atomic clock so it is very accurate.

Thank you, Sir, for your prompt response. You are a true professional to the core. I'm glad I got in touch with you through your videos. Take care and stay safe. God bless.

Why don't you polish the main plate and the bridge after resizing like you do with the barrel?

@watchrepairtutorials Год назад

You caught that. I forgot to add that in, but it certainly is good practice.

Hairspring is my biggest pain.

You’re not the only one brother

@loungebiddle7922 Год назад

...yes, used up my two practice movement hairsprings practicing techniques to get spacings correct, aligned so during regulation there is always a gap along the spring, installing ensures spring is parallel to wheel, and beat error minimised, but biggest fail for me was the kink up or down. Found a old old video on using pyth (pith) wood to lay spring so kink is up. Then firm grip with perfect honed tweezers push vertically down into wood. Hey presto, only putting pressure in exact place of the kink. I still will approach hairspring and balance wheel disassembly and reassembly with a lot, a lot of care and respect. I work on vintage so no room for error.

Ok I watched one vid and commented that you did not show putting the watch back in beat. Then I watch another one that shows you doing it. Yikes I have to stop commenting and just watch more

The BE should always be under 0.9 ms. Period. I’ll be more careful in the future when I service and movement not to leave any steps out so there’s no confusion.

Hi Alex i'm chasing lost amplitude on a seiko NH35 Movement .whilst taking it apart i did not release all the tension on the mainspring when i removed the pallet fork and the escapement went flying around so fast the it made a hell of a noise and obviously the mainspring unwound unattended would this bad practice be the reason my Amplitude has basically halved cheers in advance

@watchrepairtutorials Год назад

I’m sure it is. It’s possible that a pivot was bent among many other things that could’ve happened.

@orgazmick Год назад

@@watchrepairtutorials cheers Alex ill check/replace the mainspring and check the pivots cheers Michael
